CA Digital Art & Mixed Media 2 — Questions and Answers
Question 1: Which blending mode in digital painting multiplies the base color with the blend color, always resulting in a darker output?
- Screen
- Multiply (Correct answer)
- Overlay
- Luminosity
Correct answer: Multiply
Multiply blending mode multiplies the base and blend color values, which always produces an equal or darker result.
Question 2: When combining traditional watercolor washes with digital elements in mixed media, which technique best preserves the organic texture of the physical layer?
- Scan at 72 dpi and apply Gaussian blur
- Photograph under flat studio lighting and desaturate
- Scan at 600 dpi or higher and use layer masks to isolate areas (Correct answer)
- Apply a texture filter in Photoshop to simulate watercolor
Correct answer: Scan at 600 dpi or higher and use layer masks to isolate areas
High-resolution scanning captures fine grain and texture detail, while layer masks allow precise non-destructive integration with digital elements.
Question 3: A digital artist wants to create a seamless repeating pattern for fabric printing. Which file format best preserves quality at any scale?
- JPEG
- PNG
- SVG (Correct answer)
- GIF
Correct answer: SVG
SVG is a vector format that scales infinitely without quality loss, making it ideal for patterns that must print at various sizes.
Question 4: In digital illustration, what is the primary advantage of working with a non-destructive workflow using adjustment layers?
- It reduces file size significantly
- It allows edits to be modified or removed without altering the original pixel data (Correct answer)
- It automatically exports to multiple formats
- It increases rendering speed
Correct answer: It allows edits to be modified or removed without altering the original pixel data
Adjustment layers apply changes non-destructively, meaning original pixel data remains intact and edits can be tweaked or removed at any time.
Question 5: Which color model is most appropriate when creating digital artwork intended for screen display?
- CMYK
- RGB (Correct answer)
- LAB
- Pantone
Correct answer: RGB
RGB (Red, Green, Blue) is the additive color model used by screens, making it the correct choice for digital display artwork.
Question 6: An artist is compositing a hand-drawn ink sketch with a digital color background. Which Photoshop layer blending mode would make the white paper of the scanned sketch transparent while keeping the dark ink lines visible?
- Screen
- Multiply (Correct answer)
- Dissolve
- Lighten
Correct answer: Multiply
Multiply mode makes white areas transparent while dark ink lines remain visible, making it ideal for compositing sketches over colored backgrounds.
Question 7: What does 'bit depth' refer to in the context of a digital image?
- The number of pixels per inch
- The number of color channels in an image
- The number of bits used to represent the color of each pixel (Correct answer)
- The compression ratio applied to the file
Correct answer: The number of bits used to represent the color of each pixel
Bit depth refers to the number of bits used per pixel to store color information; higher bit depth allows more color gradations.
