Which color mode provides the largest gamut and is recommended for color correction when maximum tonal flexibility is needed before converting to output profiles?
Answer: ProPhoto RGB
ProPhoto RGB encompasses a very wide gamut—larger than Adobe RGB and sRGB—making it ideal for intermediate editing to preserve the most color information.
What is 'metamerism' and why is it relevant to color correction in Photoshop?
Answer: Two colors appearing identical under one light source but different under another, affecting how corrections translate across viewing conditions
Metamerism occurs when colors match under one illuminant but differ under another, so color corrections made under a specific light may not look correct in other environments.
In a Curves adjustment, what does an S-curve achieve?
Answer: Increases contrast by lightening midtone highlights and darkening midtone shadows
An S-curve raises the upper midtones and lowers the lower midtones simultaneously, creating a contrast boost throughout the image.
Which Photoshop command allows you to soft-proof an image to simulate how it will look when printed on a specific output profile?
Answer: View > Proof Colors (with a custom proof setup)
View > Proof Colors activates soft proofing using the profile configured in View > Proof Setup, simulating the output device's color rendering on screen.
What does the 'Black Clip' warning in the Histogram panel indicate?
Answer: Shadow pixels are being clipped to pure black, losing detail
The black clip warning signals that some shadow pixel values have been pushed to level 0 (pure black), meaning detail in those areas is permanently lost.
Which method should be used to match the color and tone of two different photos so that one blends seamlessly into the other?
Answer: Image > Adjustments > Match Color
Match Color analyzes the luminance, color range, and saturation of a source image and adjusts the target image to match those statistics.
When correcting skin tones in a portrait, which Info panel readout is most commonly used as a reference to ensure accurate flesh tone values in RGB?
Answer: Red channel highest, Green second, Blue lowest (e.g., R:220 G:180 B:160)
Healthy skin tones in RGB should have Red as the highest value, followed by Green, then Blue as the lowest, with specific ratios varying by complexion.
