What is 'metamerism' in the context of product color accuracy?
Answer: When two colors appear identical under one light source but different under another
Metamerism occurs when two surfaces reflect different spectral combinations but appear to match under specific lighting conditions, and diverge under others.
What advantage does the L*a*b* (LAB) color model offer for product photo editing?
Answer: It separates luminosity from color, allowing independent adjustments
LAB separates the lightness channel (L) from the color channels (a and b), making it easier to adjust tone without affecting color and vice versa.
When a product image has a green color cast, which channel adjustment in RGB would most directly correct it?
Answer: Reduce the green channel or boost the red and blue channels
A green cast means there is excess green; reducing the green channel or boosting its complementary colors (red and blue) will neutralize it.
Why is monitor calibration especially important in a product photography workflow?
Answer: It ensures the colors you edit are accurately represented, so the client's product colors are correct
An uncalibrated monitor may display colors inaccurately, causing editors to make adjustments that look correct on screen but are wrong on other devices.
A product photo of a red jacket appears correct on your calibrated monitor but looks too orange when printed. What is the most likely cause?
Answer: The image was not converted to the correct output color profile before printing
A color shift between screen and print usually means the image was sent to the printer without the appropriate output ICC profile applied.
What is the D50 standard illuminant used for in the printing and color management industry?
Answer: It is the standard reference light source for evaluating printed color
D50 (5000K daylight) is the standard illuminant used in print viewing booths to evaluate color proofs consistently across different facilities.
When shooting product photos for a client who sells both online and in print catalogs, which workflow best handles both outputs?
Answer: Shoot RAW, edit in Adobe RGB, deliver sRGB for web and CMYK-converted files for print
Shooting RAW and editing in the wider Adobe RGB space preserves maximum color data, then converting to sRGB for web and CMYK for print ensures optimal output for each medium.
