Image Editing Color Correction and Grading 1 — Questions and Answers
Question 1: Which color model uses Hue, Saturation, and Brightness to define colors?
- RGB
- CMYK
- HSB (Correct answer)
- LAB
Correct answer: HSB
HSB (Hue, Saturation, Brightness) is a color model that describes colors based on human perception.
Question 2: What tool in Photoshop allows you to adjust the tonal range of an image using a graph?
- Hue/Saturation
- Curves (Correct answer)
- Color Balance
- Vibrance
Correct answer: Curves
The Curves tool uses a graph to let you precisely adjust the tonal values across highlights, midtones, and shadows.
Question 3: What does the term 'white balance' refer to in image editing?
- Increasing image brightness
- Correcting color temperature to make whites appear neutral (Correct answer)
- Removing all color from an image
- Boosting saturation of white tones
Correct answer: Correcting color temperature to make whites appear neutral
White balance correction adjusts the color temperature of an image so that neutral whites are not tinted warm or cool.
Question 4: Which color channel in LAB color mode contains only luminance (brightness) data?
- A channel
- B channel
- L channel (Correct answer)
- C channel
Correct answer: L channel
The L channel in LAB color mode stores only the lightness information, while A and B store color data.
Question 5: What is the purpose of the 'Vibrance' adjustment in Photoshop?
- Sharpens edges
- Boosts saturation of muted colors while protecting already-saturated colors (Correct answer)
- Converts image to grayscale
- Increases contrast
Correct answer: Boosts saturation of muted colors while protecting already-saturated colors
Vibrance intelligently increases saturation on less-saturated colors while preventing oversaturation of already vivid hues.
Question 6: What is 'color grading' primarily used for in professional image editing?
- Removing noise from images
- Applying a consistent creative color tone or mood (Correct answer)
- Resizing images for print
- Merging multiple exposures
Correct answer: Applying a consistent creative color tone or mood
Color grading applies intentional color tones to create a specific mood or cinematic look in an image.
