ACE Image Adjustments and Retouching 3 — Questions and Answers
Question 1: Which tool in Photoshop uses Content-Aware technology to fill a removed object by analyzing surrounding pixels?
- Spot Healing Brush (Content-Aware mode) (Correct answer)
- Clone Stamp Tool
- Smudge Tool
- Background Eraser
Correct answer: Spot Healing Brush (Content-Aware mode)
In Content-Aware mode, the Spot Healing Brush synthesizes replacement pixels by analyzing nearby texture and color.
Question 2: When using Shadows/Highlights, what does the 'Tonal Width' slider control?
- The brightness range of pixels affected by the correction (Correct answer)
- The amount of noise introduced by the adjustment
- The radius of the local correction area
- The blend between color channels
Correct answer: The brightness range of pixels affected by the correction
Tonal Width determines how wide a range of tonal values is considered a shadow or highlight for the adjustment.
Question 3: What does the 'Vibrance' adjustment do differently compared to 'Saturation'?
- Vibrance boosts all colors equally while Saturation protects skin tones
- Vibrance selectively boosts less-saturated colors while protecting already-saturated tones (Correct answer)
- Vibrance only affects the red channel while Saturation affects all channels
- Vibrance applies to CMYK images while Saturation applies to RGB
Correct answer: Vibrance selectively boosts less-saturated colors while protecting already-saturated tones
Vibrance uses a non-linear saturation increase that pushes muted colors more than already-vivid ones, preventing oversaturation.
Question 4: In Photoshop's Match Color feature, what is the 'Luminance' slider used for?
- Adjusting the brightness of the matched result (Correct answer)
- Setting the source layer for the color match
- Controlling how closely the color statistics are matched
- Desaturating the target image after matching
Correct answer: Adjusting the brightness of the matched result
The Luminance slider in Match Color brightens or darkens the matched image after the color statistics are applied.
Question 5: Which of the following retouching tools samples from a defined source point and does NOT blend with the destination's color and luminosity?
- Spot Healing Brush
- Clone Stamp Tool (Correct answer)
- Healing Brush Tool
- Patch Tool
Correct answer: Clone Stamp Tool
The Clone Stamp Tool copies pixels exactly from the source point without any blending calculation with the target area.
Question 6: What does enabling 'Use All Layers' in the Healing Brush options do?
- Merges all layers before applying the heal
- Allows the tool to sample pixel data from every visible layer (Correct answer)
- Restricts healing to the current layer only
- Automatically creates a new layer for the healed content
Correct answer: Allows the tool to sample pixel data from every visible layer
Use All Layers lets the Healing Brush sample from merged composite data of all visible layers while writing corrections to the current (or a new) layer.
Question 7: When applying a Black & White adjustment layer, what does dragging the 'Reds' slider to the left do?
- Darkens areas of the image that were originally red (Correct answer)
- Removes all red channel data from the image
- Brightens areas of the image that were originally red
- Shifts red hues toward yellow in the grayscale output
Correct answer: Darkens areas of the image that were originally red
Moving the Reds slider left darkens the luminosity of pixels that contained red in the original color image.
