Which Photoshop feature lets you set a target output color for neutrals (gray, white, black) in Curves by double-clicking the eyedroppers?
Answer: Auto Color Correction Options
Double-clicking the shadow, midtone, or highlight eyedroppers in Curves opens the Auto Color Correction Options where you set target neutral values.
What is the advantage of working in 16-bit mode when making color corrections?
Answer: More tonal levels exist, reducing banding and posterization
16-bit mode provides 65,536 tonal levels per channel versus 256 in 8-bit, dramatically reducing the risk of posterization when editing.
When using the Vibrance adjustment, how does it treat already-saturated colors differently from less-saturated ones?
Answer: It applies less boost to already-saturated colors to prevent clipping
Vibrance uses a non-linear boost that increases saturation more in muted colors and less in already-saturated ones, protecting skin tones and rich hues.
What does the 'Absolute Colorimetric' rendering intent do to out-of-gamut colors?
Answer: Clips them to the nearest reproducible color
Absolute Colorimetric clips any out-of-gamut colors to the nearest value within the destination gamut without adjusting in-gamut colors.
In Photoshop, what is the primary purpose of assigning (not converting to) a different color profile to an image?
Answer: Change how the existing pixel values are interpreted and displayed
Assigning a profile reinterprets the existing pixel numbers under a new color space definition without changing the actual pixel values.
Which Photoshop adjustment is most effective for correcting color fringing (chromatic aberration) along high-contrast edges?
Answer: Lens Correction filter's Chromatic Aberration controls
The Lens Correction filter has dedicated Chromatic Aberration sliders that shift red/cyan and blue/yellow channels to align color fringing on edges.
You want to increase local contrast and make colors 'pop' without shifting hue. Which technique works best?
Answer: Add a Curves layer set to Luminosity blend mode with an S-curve
A Curves S-curve on a Luminosity blend mode layer boosts contrast in tonal values only, leaving color hue and saturation unchanged.
