ACE Image Editing & Retouching 3 — Questions and Answers
Question 1: Which Photoshop feature lets you remove a repetitive background element by analyzing and replacing it with surrounding content in one step?
- Spot Healing Brush in Proximity Match mode
- Content-Aware Fill workspace (Correct answer)
- Clone Stamp with Pattern overlay
- Neural Filters Background Blur
Correct answer: Content-Aware Fill workspace
The Content-Aware Fill workspace lets you define a sampling region and preview the fill before applying it to remove unwanted elements.
Question 2: In frequency separation retouching, which layer holds the color and tonal information?
- The high-frequency layer set to Linear Light
- The low-frequency layer beneath the high-frequency layer (Correct answer)
- A merged stamp visible layer on top
- An adjustment layer clipped to the high-frequency layer
Correct answer: The low-frequency layer beneath the high-frequency layer
In frequency separation, the low-frequency layer contains color and tonal gradients (blurred), while the high-frequency layer holds texture and fine detail.
Question 3: What is the main advantage of using a luminosity mask for dodging highlights in a landscape photo?
- It sharpens edges before brightening them
- It targets pixels based on their brightness, protecting shadows automatically (Correct answer)
- It converts the image to Lab color before dodging
- It creates a stamped merge of all layers
Correct answer: It targets pixels based on their brightness, protecting shadows automatically
Luminosity masks select pixels based on their brightness values, so a highlight mask automatically protects shadows from being affected during dodging.
Question 4: When using Warp Transform, what does the 'Split Warp' command (right-click) allow you to do?
- Split the layer into two separate layers at the warp point
- Add a horizontal or vertical dividing line to control localized warping (Correct answer)
- Apply the warp to only one color channel
- Reset individual grid points without undoing all changes
Correct answer: Add a horizontal or vertical dividing line to control localized warping
Split Warp adds a cross, horizontal, or vertical split line inside the warp grid, enabling localized control over specific regions of the warp.
Question 5: Which method best preserves edge quality when retouching hair against a complex background using a selection?
- Magic Wand with a high tolerance setting
- Select and Mask workspace with Refine Edge Brush on hair edges (Correct answer)
- Quick Selection tool followed by Contract by 2px
- Color Range selection set to Highlights
Correct answer: Select and Mask workspace with Refine Edge Brush on hair edges
The Refine Edge Brush inside Select and Mask analyzes fine hair strands against complex backgrounds, producing the highest-quality hair selections.
Question 6: What happens when you Alt-click (Option-click on Mac) on a layer mask thumbnail in the Layers panel?
- The mask is deleted without warning
- The canvas displays only the mask in grayscale (Correct answer)
- The mask is inverted permanently
- The layer below the mask is selected
Correct answer: The canvas displays only the mask in grayscale
Alt/Option-clicking a layer mask thumbnail switches the canvas view to show the mask itself as a grayscale image, useful for inspecting and painting mask details.
Question 7: In the Reduce Noise filter, what does the 'Preserve Details' slider control?
- How strongly edges are protected from noise removal (Correct answer)
- The threshold for color noise versus luminance noise
- The amount of sharpening applied after noise reduction
- The radius of the smoothing algorithm
Correct answer: How strongly edges are protected from noise removal
The Preserve Details slider determines how much edge and fine detail is protected when the noise reduction algorithm smooths the image.
