ACE - Adobe Certified Expert in Photoshop — Questions and Answers
Question 1: When using Select and Mask, which edge refinement method works best for selecting fine hair or fur?
- Geometric mode
- Polygon Lasso painting
- Smart Radius with the Refine Edge Brush (Correct answer)
- Threshold-based color selection
Correct answer: Smart Radius with the Refine Edge Brush
Enabling Smart Radius and painting with the Refine Edge Brush allows Photoshop to intelligently detect and include fine strands of hair or fur in the selection.
Question 2: What does the 'Decontaminate Colors' option in Refine Edge/Select and Mask do?
- Removes color casts from the entire image
- Replaces fringe pixels with colors from nearby edge pixels (Correct answer)
- Converts the selection to a grayscale mask
- Neutralizes the background color before extraction
Correct answer: Replaces fringe pixels with colors from nearby edge pixels
Decontaminate Colors replaces residual background-colored fringe pixels near extracted edges with colors sampled from the foreground subject.
Question 3: To select all pixels on a layer (load its transparency as a selection), you:
- Shift-click the layer thumbnail
- Press Ctrl/Cmd+A
- Alt/Option-click the layer thumbnail
- Ctrl/Cmd-click the layer thumbnail (Correct answer)
Correct answer: Ctrl/Cmd-click the layer thumbnail
Ctrl/Cmd-clicking a layer thumbnail loads the layer's non-transparent pixels as a selection, useful before creating masks.
Question 4: Which blending mode is most effective for darkening a composite where the layer acts like ink — multiplying colors together so the result is always darker than the original?
- Color Burn
- Linear Burn
- Darken
- Multiply (Correct answer)
Correct answer: Multiply
Multiply blending mode mathematically multiplies the base and blend colors, always producing a darker result — white pixels become transparent, making it ideal for shadows and ink effects.
Question 5: In Camera Raw, what does the 'Clarity' slider primarily affect?
- Midtone contrast and local texture (Correct answer)
- Shadow recovery in dark areas
- Global brightness of the image
- Color saturation of neutral tones
Correct answer: Midtone contrast and local texture
Clarity increases midtone contrast, enhancing local texture and giving images a crisper, more defined look.
Question 6: Which Photoshop command lets you soft-proof how an image will look when printed on a specific printer profile before exporting?
- Image > Adjustments > Hue/Saturation
- View > Proof Colors with a custom proof setup (Correct answer)
- Filter > Render > Lighting Effects
- View > Gamut Warning
Correct answer: View > Proof Colors with a custom proof setup
View > Proof Colors (with a proof setup configured under View > Proof Setup) simulates on-screen how the image will render under a chosen output color profile.
Question 7: When using Free Transform, which keyboard shortcut switches to Distort mode, allowing each corner handle to be moved independently?
- Hold Shift while dragging a corner
- Hold Ctrl/Cmd while dragging a corner (Correct answer)
- Hold Alt/Option while dragging a corner
- Hold Spacebar while dragging a corner
Correct answer: Hold Ctrl/Cmd while dragging a corner
While in Free Transform, holding Ctrl (Windows) or Cmd (Mac) while dragging a corner handle switches to Distort mode, which lets you move each corner independently rather than scaling the entire bounding box. This is useful for skewing or creating perspective-like effects manually.
Question 8: Which Smart Object command creates an independent copy whose contents can be edited separately from the original?
- Duplicate Layer
- Layer > Merge Down
- Edit > Copy Merged
- New Smart Object via Copy (Correct answer)
Correct answer: New Smart Object via Copy
New Smart Object via Copy creates a new Smart Object with independent contents, unlike Duplicate Layer which creates a linked copy sharing the same source.
Question 9: In Photoshop, what is 'focus stacking' used for?
- Stacking multiple sharpening passes to enhance fine detail
- Combining images shot at different focus distances to achieve greater overall depth of field (Correct answer)
- Blending multiple exposures to recover dynamic range
- Merging HDR photos from a single RAW file
Correct answer: Combining images shot at different focus distances to achieve greater overall depth of field
Focus stacking merges several shots taken at different focal planes so that the combined image is sharp from foreground to background.
Question 10: What does 'Flatten Image' do to a Photoshop document?
- Converts all layers to Smart Objects
- Removes all color profiles and resets to sRGB
- Reduces the canvas to its smallest bounding box
- Merges all visible layers into one Background layer and discards hidden layers (Correct answer)
Correct answer: Merges all visible layers into one Background layer and discards hidden layers
Flatten Image merges all visible layers into a single Background layer and permanently discards any hidden layers.
Question 11: Which Photoshop tool would you use to lighten the iris of an eye while protecting the surrounding skin from being affected?
- Exposure adjustment layer with a layer mask (Correct answer)
- Dodge Tool with Range set to Highlights
- Brightness/Contrast adjustment with a gradient mask
- Burn Tool with Range set to Shadows
Correct answer: Exposure adjustment layer with a layer mask
An Exposure adjustment layer paired with a precise layer mask lets you lighten only the painted iris area non-destructively.
Question 12: In Photoshop, what happens when you Alt-click (Option-click) an anchor point with the Convert Point tool?
- It deletes the anchor point
- It splits the path at that anchor
- It adds a new anchor point beside it
- It converts a smooth point to a corner point (Correct answer)
Correct answer: It converts a smooth point to a corner point
Alt/Option-clicking a smooth anchor point with Convert Point tool retracts its handles, converting it to a corner point.
Question 13: A designer is creating a composite image and needs to apply a Curves adjustment layer, but only to the layer immediately below it, which contains a specific object. Which of the following is the most efficient method to achieve this without affecting any other layers?
- Use a layer mask on the adjustment layer and paint over the object.
- Group the adjustment layer with the object layer.
- Create a clipping mask. (Correct answer)
- Merge the adjustment layer with the object layer.
Correct answer: Create a clipping mask.
Creating a clipping mask is the most direct and non-destructive way to have an adjustment layer (or any layer) affect only the single layer directly beneath it. The content of the bottom layer 'clips' the layer above. Grouping would require masking the group, merging is destructive, and manually painting a layer mask is less efficient than a clipping mask for this purpose.
Question 14: When restoring detail in a severely overexposed area of a JPEG, what is the realistic limitation?
- Camera Raw cannot open JPEG files
- Curves adjustments will introduce banding on JPEGs
- Completely blown highlights contain no recoverable data in any channel (Correct answer)
- The Shadows/Highlights adjustment cannot process JPEGs
Correct answer: Completely blown highlights contain no recoverable data in any channel
Pixels clipped to pure white (255,255,255) in all channels contain no information to recover, making highlight restoration impossible in those areas.
Question 15: What is the purpose of using Smart Objects in a Photoshop workflow?
- To apply non-destructive edits (Correct answer)
- To export web graphics
- To crop images
- To flatten layers
Correct answer: To apply non-destructive edits
The purpose of using Smart Objects in a Photoshop workflow is to apply non-destructive edits and transformations. When an image or layer is converted to a Smart Object, its original content is preserved, allowing you to scale, rotate, transform, or apply filters multiple times without any loss of quality. This ensures maximum flexibility and editability throughout your project, as you can always revert to the original state.
Question 16: When restoring a damaged photograph with large missing sections, which workflow preserves the most non-destructive flexibility?
- Paint directly on the background layer
- Duplicate the layer and use Clone Stamp
- Use the Patch Tool on a flattened copy
- Apply Content-Aware Fill to a blank layer above the original (Correct answer)
Correct answer: Apply Content-Aware Fill to a blank layer above the original
Applying Content-Aware Fill to a separate blank layer keeps the original untouched and allows independent editing of the repair.
Question 17: You are designing a website mockup and want to place a photograph inside a perfect circular frame. The frame must remain editable, allowing you to easily resize it later without losing its sharp edge. Which of the following is the best method to achieve this non-destructively?
- Use the Elliptical Marquee tool to create a circular selection and apply a layer mask.
- Use the Ellipse tool to draw a circle and apply it as a vector mask on the photo layer. (Correct answer)
- Erase the area around the circle on the photo layer using the Eraser tool.
- Create a new layer, draw a circle with the Brush tool, and use it as a clipping mask.
Correct answer: Use the Ellipse tool to draw a circle and apply it as a vector mask on the photo layer.
A vector mask uses a vector path to define the visible areas of a layer. This creates a clean, hard-edged mask that is resolution-independent, meaning it can be scaled or transformed at any time without degrading the quality of the mask's edge. Using the Ellipse tool ensures a perfect, editable circle for the mask.
Question 18: When painting a layer mask with a soft brush, which foreground/background color combination will reveal the layer content in the painted area?
- Black foreground
- 50% gray foreground
- Any color — mask painting ignores hue
- White foreground (Correct answer)
Correct answer: White foreground
On a layer mask, white reveals (makes pixels visible) and black conceals — painting with white exposes the layer's content in that area.
Question 19: What is the difference between 'Apply Image' and a standard layer mask when masking a layer?
- Apply Image only works on the Background layer
- Apply Image can use channel and blending data from any open document to build a complex mask calculation (Correct answer)
- Apply Image masks are permanently destructive while standard masks are not
- Apply Image is faster but lower quality
Correct answer: Apply Image can use channel and blending data from any open document to build a complex mask calculation
Apply Image calculates and composites any channel, layer, or blending mode combination from the current or another open document directly into a mask or channel, enabling complex channel-based masking beyond what a simple brush can achieve.
Question 20: Which compression type in Photoshop's TIFF save dialog produces the smallest file size for photographic images?
- JPEG (Correct answer)
- None
- ZIP
- LZW
Correct answer: JPEG
JPEG compression within TIFF produces the smallest file sizes for photographic content, though it introduces lossy compression unlike LZW or ZIP.
Question 21: When removing moiré patterns from a scanned image, the most targeted approach is to:
- Increase Clarity in Camera Raw to override the pattern
- Use the Reduce Noise filter's Per Channel controls to target the affected channel (Correct answer)
- Apply Gaussian Blur to the entire image
- Apply Unsharp Mask at a wide radius
Correct answer: Use the Reduce Noise filter's Per Channel controls to target the affected channel
Reduce Noise's Per Channel mode lets you apply noise reduction selectively to the specific color channel where moiré interference appears.
Question 22: When a Smart Filter is applied to a Smart Object, what does the mask thumbnail attached to the filter do?
- Controls the opacity of the entire Smart Object
- Allows selective masking of where the Smart Filter is visible (Correct answer)
- Converts the filter effect to a new layer
- Links the filter to an adjustment layer above
Correct answer: Allows selective masking of where the Smart Filter is visible
The Smart Filter mask lets you paint with black to hide filter effects in specific areas, giving precise control over filter application.
Question 23: Which retouching approach is recommended when removing wrinkles while preserving natural skin texture?
- Gaussian Blur on a new layer set to Lighten mode
- Heal or clone onto a separate layer then reduce that layer's opacity (Correct answer)
- Use the Smudge Tool at 100% strength
- Apply a Surface Blur directly on the Background layer
Correct answer: Heal or clone onto a separate layer then reduce that layer's opacity
Healing or cloning to a separate layer and reducing its opacity blends the correction with the original, softening wrinkles while retaining texture.
Question 24: When would you use File > Place Embedded versus File > Place Linked when building a Photoshop composite?
- Place Linked for assets you want to update dynamically from an external file; Place Embedded to bake the asset into the PSD (Correct answer)
- Both options produce identical results with different icons
- Place Embedded for assets you want to update dynamically from an external file; Place Linked to bake the asset into the PSD permanently
- Place Linked is only available when working with Creative Cloud Libraries
Correct answer: Place Linked for assets you want to update dynamically from an external file; Place Embedded to bake the asset into the PSD
Place Linked references an external file and updates automatically if the source changes, while Place Embedded copies the file data directly into the PSD.
Question 25: Which tool is best suited for retouching a subject's eyes to increase iris brightness and color saturation without affecting surrounding areas?
- Vibrance adjustment layer applied to the entire image
- Sponge tool set to Saturate with a small brush
- Hue/Saturation adjustment layer with a precise painted mask over the irises (Correct answer)
- Color Balance adjustment with a luminosity mask for the iris
Correct answer: Hue/Saturation adjustment layer with a precise painted mask over the irises
A Hue/Saturation adjustment layer with a mask painted precisely over the irises isolates the color and saturation enhancement to just the eyes.
Question 26: You want a layer to appear only inside a shape on the layer below. Which technique achieves this non-destructively without using a selection?
- Erase pixels outside the shape on the upper layer
- Clipping mask with the upper layer clipped to the shape layer (Correct answer)
- Merge the two layers
- Layer mask on the upper layer painted manually
Correct answer: Clipping mask with the upper layer clipped to the shape layer
Creating a clipping mask clips the upper layer's content to the boundaries of the shape layer below, non-destructively.
Question 27: A retoucher needs to remove a large, irregularly shaped object from a complex background, like a person standing in a detailed forest scene. The Content-Aware Fill command is producing unnatural results. Which tool allows the user to manually select the distracting area and then drag that selection to a different source area to sample from, offering more direct control over the replacement texture?
- Clone Stamp Tool
- Spot Healing Brush Tool
- Remove Tool
- Patch Tool (Correct answer)
Correct answer: Patch Tool
The Patch Tool, especially in its Content-Aware mode, is ideal for this scenario. It allows the user to make a selection around the unwanted object and then drag that selection to a clean source area. Photoshop then blends the source texture into the target area, providing more user control over the final result compared to the more automated Content-Aware Fill.
Question 28: Which Camera Raw / Lightroom panel control is equivalent to a targeted midtone brightness adjustment in Curves?
- Exposure slider (Correct answer)
- Blacks slider
- Gamma slider
- Shadows slider
Correct answer: Exposure slider
The Exposure slider in Camera Raw acts as an overall brightness/midtone control, similar to moving the midpoint of the Curves adjustment.
Question 29: In a composite workflow, what is the primary advantage of using a Smart Object layer before applying transformations?
- Smart Objects automatically generate a layer mask from the subject
- Smart Objects allow the layer to be used across multiple documents simultaneously
- Smart Objects enable GPU-accelerated rendering for all filters
- Smart Objects preserve original pixel data so transformations remain non-destructive and reversible (Correct answer)
Correct answer: Smart Objects preserve original pixel data so transformations remain non-destructive and reversible
Smart Objects store original source data internally, so you can scale, rotate, and warp the layer repeatedly without accumulating pixel degradation.
Question 30: Which blending mode is ideal for combining a neutral 50% gray layer with the image to add dodge-and-burn non-destructively?
- Multiply
- Overlay (Correct answer)
- Screen
- Difference
Correct answer: Overlay
Overlay mode renders 50% gray as invisible, so painting lighter or darker on such a layer dodges or burns the composite non-destructively.
Question 31: A vector mask differs from a layer mask because it:
- Uses grayscale painting to hide pixels
- Is resolution-independent and defined by paths (Correct answer)
- Must be converted from a selection
- Supports feathering by default
Correct answer: Is resolution-independent and defined by paths
Vector masks use resolution-independent Bezier paths to define the visible area, resulting in sharp, scalable edges unlike pixel-based layer masks.
Question 32: When working with a 16-bit image, which statement about tonal adjustments is most accurate?
- Curves adjustments are not available
- Color range is identical to 8-bit but files are smaller
- Adjustments are applied twice as fast
- More headroom for aggressive adjustments with less banding than 8-bit (Correct answer)
Correct answer: More headroom for aggressive adjustments with less banding than 8-bit
16-bit images store 65,536 tonal values per channel, providing much more data to redistribute before posterization or banding occurs.
Question 33: What is the purpose of setting a 'Bleed' area when preparing a Photoshop document for commercial printing?
- It extends background colors and images beyond the trim edge to prevent white borders after cutting (Correct answer)
- It controls the ink density limit for CMYK output
- It adds safety margin for color profile embedding
- It defines the non-printing margin inside the document
Correct answer: It extends background colors and images beyond the trim edge to prevent white borders after cutting
Bleed extends artwork 1/8 inch (0.125") beyond the trim edge so that slight cutting variations don't result in unwanted white borders on the final printed piece.
Question 34: You are preparing a vibrant RGB image for printing on a standard CMYK press. You notice that Photoshop's Gamut Warning highlights several areas, indicating that those colors are outside the destination CMYK color space. Which Rendering Intent is designed to compress the entire color range of the source space into the destination gamut, preserving the relative relationships between colors to create a visually pleasing result, even if it alters in-gamut colors?
- Saturation
- Absolute Colorimetric
- Relative Colorimetric
- Perceptual (Correct answer)
Correct answer: Perceptual
The Perceptual rendering intent aims to preserve the overall visual relationship between colors by compressing the entire source gamut into the destination gamut. This often results in a more natural and photographically pleasing conversion for images with many out-of-gamut colors, even though it may slightly alter colors that were originally within the destination gamut.
Question 35: A designer wants to use an old photograph whose creator died in 1920. What is most likely true about this image in the United States?
- It is in the public domain and can be used freely (Correct answer)
- It is still protected by copyright and cannot be used
- It can only be used in educational projects
- It requires a Creative Commons license to use
Correct answer: It is in the public domain and can be used freely
In the United States, works published before 1928 (and generally works where the author died more than 70 years ago) have entered the public domain, meaning they are no longer protected by copyright and can be used freely by anyone for any purpose.
Question 36: What adjustment layer would you use to shift a specific range of hues without affecting others?
- Color Balance
- Vibrance
- Photo Filter
- Hue/Saturation with targeted color range (Correct answer)
Correct answer: Hue/Saturation with targeted color range
Hue/Saturation allows you to select a specific color range (Reds, Yellows, etc.) and shift only that range's hue independently.
Question 37: Which of the following describes a key advantage of converting a layer to a Smart Object before applying transformations like scaling and rotating?
- It automatically creates a layer mask for precise editing.
- It unlocks exclusive blending modes not available for regular layers.
- It allows for non-destructive editing, preserving the original image quality. (Correct answer)
- It permanently rasterizes vector content for better performance.
Correct answer: It allows for non-destructive editing, preserving the original image quality.
The primary benefit of using a Smart Object is that it embeds the source content (raster or vector) and allows for non-destructive transformations. This means you can scale, rotate, or apply filters multiple times without progressively degrading the original image data, as all changes are reversible and calculated from the original source.
Question 38: How can you apply a single layer mask to an entire Layer Group?
- Rasterize the group before masking
- Add a mask to each layer individually then link them
- Select the group layer and add a mask from the Layers panel Add Mask button (Correct answer)
- Use the Clipping Mask option on the group
Correct answer: Select the group layer and add a mask from the Layers panel Add Mask button
Selecting the Layer Group in the Layers panel and clicking the Add Layer Mask button applies a single mask that controls the visibility of all layers inside the group.
Question 39: When correcting a blue color cast in shadows using the Color Balance adjustment, which slider should you move and in which direction?
- Magenta–Green slider toward Green
- Cyan–Red slider toward Red
- Yellow–Blue slider toward Yellow (Correct answer)
- Yellow–Blue slider toward Blue
Correct answer: Yellow–Blue slider toward Yellow
Moving the Yellow–Blue slider toward Yellow in the Shadows tone balance subtracts blue from dark areas, neutralizing a blue cast.
Question 40: A designer creates a company logo in Photoshop using the Rectangle and Ellipse shape tools. What is the primary advantage of keeping these shapes as live vector shape layers instead of rasterizing them?
- They automatically have a smaller file size than raster layers.
- They can be scaled to any size without losing edge quality. (Correct answer)
- They can be painted on directly with the Brush tool.
- They allow for more complex filter effects to be applied directly.
Correct answer: They can be scaled to any size without losing edge quality.
Vector shapes are mathematically defined by paths, points, and curves, not pixels. This allows them to be scaled up or down infinitely without any degradation, aliasing, or "pixelation," which is crucial for assets like logos that are used in various sizes.
Question 41: You are exporting a large photographic hero image as a JPEG for a website. To improve the user's perceived loading experience, you want the image to display a full, low-quality version almost instantly, which then sharpens as it downloads. Which JPEG format option should you choose?
- Progressive (Correct answer)
- Baseline Optimized
- Lossless
- Baseline ('Standard')
Correct answer: Progressive
A Progressive JPEG is encoded in a way that allows it to be displayed in a series of scans or passes. This provides an immediate, full-size preview that becomes clearer as the file finishes downloading, which can improve perceived performance. Baseline JPEGs load from top to bottom. Progressive JPEGs also often have a slightly smaller file size for images over 10KB.
Question 42: In Camera Raw, the 'Graduated Filter' tool applies adjustments in what pattern?
- A linear gradient transition from one edge of the drawn region to the other (Correct answer)
- An elliptical selection limited to the center of the image
- A random feathered selection across the image
- A circular gradient from the center outward
Correct answer: A linear gradient transition from one edge of the drawn region to the other
The Graduated Filter applies a linear gradient transition, starting at full strength at one pin and fading to no effect at the other pin, mimicking a physical graduated ND filter.
Question 43: Which channel in the CMYK model serves as a separate ink that adds depth and reduces the amount of CMY inks required?
- Magenta channel
- Yellow channel
- Cyan channel
- Key (Black) channel (Correct answer)
Correct answer: Key (Black) channel
The K (Key/Black) channel provides deep shadows and neutral density, reducing expensive CMY ink usage through under-color removal.
Question 44: What does the 'Subtract from Selection' mode do when using the Rectangular Marquee tool over an existing elliptical selection?
- Creates a new separate selection region
- Converts the elliptical selection into a rectangular one
- Deselects any pixels where the new rectangular area overlaps the existing selection (Correct answer)
- Removes the entire elliptical selection and starts a new rectangular one
Correct answer: Deselects any pixels where the new rectangular area overlaps the existing selection
Subtract mode removes the overlapping portion of the new marquee from the current selection, effectively cutting a rectangular hole in the ellipse.
Question 45: Which option in the Transform command maintains the aspect ratio of a selection or layer while resizing in older versions of Photoshop (pre-CC 2019)?
- Holding Ctrl/Cmd while dragging a corner handle
- Holding Alt while dragging a corner handle
- Enabling 'Constrain Proportions' in the Options bar
- Holding Shift while dragging a corner handle (Correct answer)
Correct answer: Holding Shift while dragging a corner handle
Before CC 2019, Shift+drag on a corner handle during Free Transform constrained the aspect ratio; in CC 2019+ it became the default behavior without Shift.
Question 46: Which command converts a layer mask into a selection?
- Select > Load Selection (Correct answer)
- Layer > Flatten Image
- Filter > Extract
- Edit > Paste Special
Correct answer: Select > Load Selection
Select > Load Selection loads the luminosity values of a mask (or channel) as an active selection.
Question 47: Which of the following is considered a non-destructive editing technique in Photoshop?
- Using the Eraser tool on a raster layer.
- Applying a filter directly to a regular pixel layer.
- Using an Adjustment Layer to modify color and tone. (Correct answer)
- Making adjustments using Image > Adjustments.
Correct answer: Using an Adjustment Layer to modify color and tone.
Adjustment Layers apply color and tonal adjustments without permanently altering the pixels of the image. They can be edited, re-adjusted, or deleted at any time, making them a core component of a non-destructive workflow. The other options are destructive because they permanently change the pixel data.
Question 48: An image edited in the ProPhoto RGB color space, which has a very large gamut, is being prepared for a client who will view it on a standard web browser. Which color space should the image be converted to for the most consistent color appearance across various non-color-managed web browsers and devices?
- sRGB (Correct answer)
- ProPhoto RGB
- Adobe RGB (1998)
- CMYK
Correct answer: sRGB
sRGB is the standard color space for the web and most consumer-level devices. Converting to sRGB ensures that colors will be displayed with reasonable consistency because it is the default color space that most web browsers and non-color-managed applications assume. Leaving it in a wide-gamut space like ProPhoto RGB would result in dull, undersaturated colors on standard displays.
Question 49: Which compositing technique uses the luminosity of one layer to control the visibility of layers beneath it in a group?
- Blend If sliders in Layer Style
- Luminosity blending mode
- Knockout blending option (Correct answer)
- Clipping mask
Correct answer: Knockout blending option
The Knockout option punches through layers within a group, using the top layer's content to reveal layers below or the background based on whether Shallow or Deep knockout is set.
Question 50: Which Photoshop feature lets you export individual layers or layer groups as separate image files automatically?
- Flatten Image then Export
- File > Export > Export Layers to Files (Correct answer)
- Image Processor with layer selection
- Layer Comps to Files
Correct answer: File > Export > Export Layers to Files
File > Export > Export Layers to Files iterates through each layer or layer group and saves them as individual image files.
Question 51: What happens to Smart Object transformations (scale, rotation) when the document resolution is changed?
- All transformations are reset to 100%
- Transformations are preserved because Smart Objects store vector/resolution-independent data (Correct answer)
- Smart Objects must be re-linked after resolution changes
- Only scale is preserved; rotation values reset
Correct answer: Transformations are preserved because Smart Objects store vector/resolution-independent data
Smart Objects maintain transformation data independently of document resolution, so scaling and rotation remain intact when resolution changes.
Question 52: In Camera Raw, what does the 'Masking' slider in the Detail panel do?
- Limits sharpening to high-contrast edges (Correct answer)
- Applies sharpening only to the luminance channel
- Blends sharpening with the original at a set opacity
- Restricts noise reduction to shadow areas
Correct answer: Limits sharpening to high-contrast edges
Holding Alt/Option while dragging the Masking slider shows which areas receive sharpening; increasing it confines sharpening to edge detail.
Question 53: Which Photoshop feature should you use to create a color-accurate contact sheet proof intended to be sent to a print client for approval?
- Edit > Copy Merged, then Paste
- Image > Flatten Image, then Save As JPEG
- Export > Export As
- File > Automate > Contact Sheet II with color profile embedding (Correct answer)
Correct answer: File > Automate > Contact Sheet II with color profile embedding
Contact Sheet II automates the layout of multiple images, and embedding the color profile ensures the client sees accurate colors.
Question 54: When working with a layer mask, which of the following statements is true?
- White reveals the layer's content, and black conceals it. (Correct answer)
- A layer mask permanently deletes the pixels it hides.
- Painting with gray on the mask will make the layer completely transparent.
- Layer masks can only be created from a selection.
Correct answer: White reveals the layer's content, and black conceals it.
On a layer mask, white represents areas where the layer is 100% visible, and black represents areas where the layer is 100% hidden (transparent). Shades of gray create partial transparency.
Question 55: In Photoshop's Glyphs panel, how do you insert an alternate glyph for a character that has OpenType alternates?
- Use Find/Replace with glyph codes
- Apply a Character Style with 'Alternate' enabled
- Use the Stylistic Sets dropdown in the Character panel
- Double-click the alternate glyph in the Glyphs panel while the cursor is in the text (Correct answer)
Correct answer: Double-click the alternate glyph in the Glyphs panel while the cursor is in the text
Double-clicking an alternate in the Glyphs panel inserts it at the cursor position in the active text layer.
Question 56: What is the effect of holding Alt/Option while clicking a layer mask thumbnail in the Layers panel?
- Inverts the mask
- Deletes the layer mask
- Displays the mask as a grayscale image on the canvas (Correct answer)
- Toggles the mask on and off
Correct answer: Displays the mask as a grayscale image on the canvas
Alt/Option+clicking a layer mask thumbnail switches the canvas view to display the raw grayscale mask, making it easy to paint or inspect its details.
