Question 1: What does the Dodge tool do when applied to an image?
- Darkens pixels in the painted area
- Lightens pixels in the painted area (Correct answer)
- Removes color saturation from the painted area
- Blurs edges in the painted area
Correct answer: Lightens pixels in the painted area
The Dodge tool lightens pixels in the area you paint over, mimicking the darkroom technique of holding back light during exposure.
Question 2: Which color mode provides the largest gamut and is recommended for images that will only be displayed on screens?
- CMYK
- Lab Color
- RGB (Correct answer)
- Grayscale
Correct answer: RGB
RGB (Red, Green, Blue) is the native color mode for monitors and provides a wider gamut for screen display than CMYK, which is optimized for print.
Question 3: In Photoshop's Layer Style dialog, which effect adds a colored glow just inside the edges of a layer's content?
- Outer Glow
- Inner Glow (Correct answer)
- Satin
- Stroke
Correct answer: Inner Glow
Inner Glow applies a colored glow effect along the inner edges of a layer's content, adding depth and a luminous look from the inside.
Question 4: What is the primary advantage of working with 16-bit images instead of 8-bit images?
- Files are smaller and load faster
- More tonal values are available, reducing banding during heavy edits (Correct answer)
- Filters run faster in 16-bit mode
- 16-bit supports more layers
Correct answer: More tonal values are available, reducing banding during heavy edits
16-bit images contain 65,536 tonal values per channel versus 256 in 8-bit, making them far more resistant to posterization and banding when adjusted.
Question 5: Which panel allows you to save and recall custom tool settings as named presets?
- Tool Options Bar
- Tool Presets panel (Correct answer)
- Actions panel
- History panel
Correct answer: Tool Presets panel
The Tool Presets panel lets you save the current tool and its settings as a named preset that can be recalled instantly in future sessions.
Question 6: When using the Patch tool in 'Normal' mode, what is the correct workflow?
- Draw a selection around the source area, then drag it to the destination
- Draw a selection around the problem area, then drag it to the clean source area (Correct answer)
- Click the problem area and Photoshop fills automatically
- Use it only with the Content-Aware option enabled
Correct answer: Draw a selection around the problem area, then drag it to the clean source area
In Normal mode, you select the damaged or unwanted area, then drag that selection to a clean texture area you want to use as the patch source.
Question 7: What happens when you Alt-click (Option-click on Mac) on a layer mask thumbnail?
- Deletes the layer mask
- Shows the mask as a grayscale image in the document window (Correct answer)
- Applies the mask permanently
- Links the mask to a new layer
Correct answer: Shows the mask as a grayscale image in the document window
Alt-clicking (Option-clicking) the layer mask thumbnail switches the canvas view to show the mask itself as a grayscale image, making it easy to paint and refine.
