Photoshop Color Correction and Grading 2 — Questions and Answers
Question 1: What is the purpose of the Selective Color adjustment in Photoshop?
- To select and cut specific colors from the image
- To add or remove CMYK ink amounts within defined color ranges without affecting other colors (Correct answer)
- To replace one color with another
- To saturate a specific color to maximum
Correct answer: To add or remove CMYK ink amounts within defined color ranges without affecting other colors
Selective Color adjusts the levels of Cyan, Magenta, Yellow, and Black within specific color ranges (Reds, Yellows, Greens, etc.) independently.
Question 2: What does the Vibrance adjustment do differently than Saturation?
- Vibrance adjusts only warm tones; Saturation adjusts cool tones
- Vibrance intelligently boosts less-saturated colors while protecting already-saturated ones and skin tones (Correct answer)
- Vibrance works only in Lab color mode
- Vibrance reduces saturation while Saturation increases it
Correct answer: Vibrance intelligently boosts less-saturated colors while protecting already-saturated ones and skin tones
Vibrance applies a non-linear saturation boost, increasing muted colors more aggressively while protecting already-vivid colors and human skin tones from oversaturation.
Question 3: Which Photoshop color mode provides the widest color gamut for print production?
- RGB
- CMYK
- Lab Color (Correct answer)
- Grayscale
Correct answer: Lab Color
Lab Color has a gamut that encompasses both RGB and CMYK, making it the widest-gamut mode in Photoshop and ideal for certain color conversions.
Question 4: What is the function of the Gradient Map adjustment layer in Photoshop?
- Fills the layer with a gradient
- Maps the grayscale tonal range of the image to a chosen gradient's colors (Correct answer)
- Creates a color overlay using gradient presets
- Generates a gradient based on sampled colors
Correct answer: Maps the grayscale tonal range of the image to a chosen gradient's colors
Gradient Map replaces each pixel's luminosity value with the corresponding color from a gradient — shadows map to the left color, highlights to the right.
Question 5: In Camera Raw within Photoshop, what does the Clarity slider adjust?
- Overall brightness of the image
- Midtone contrast to enhance texture and detail (Correct answer)
- The white balance temperature
- The sharpening radius of edges
Correct answer: Midtone contrast to enhance texture and detail
Clarity increases local contrast in the midtones, adding perceived sharpness and texture detail without affecting the overall exposure.
Question 6: What is the purpose of the Photo Filter adjustment layer in Photoshop?
- Applies lens distortion correction
- Simulates placing a colored warming or cooling filter in front of the camera lens (Correct answer)
- Converts images to black and white using channel mixing
- Applies a blur effect to the image
Correct answer: Simulates placing a colored warming or cooling filter in front of the camera lens
Photo Filter mimics traditional photographic gel filters, allowing you to warm (orange/yellow) or cool (blue) the overall color temperature of an image.
