Feeling confident about file types and color models? Try these exercises for practice. They are not graded.
Choose an answer for each item, then select Check answers. Wrong answers turn red so you can try again.
1. Raster or vector?
2. Image Size or Canvas Size?
Which Photoshop command would you use?
3. Lossless or lossy?
4. Which file type?
Pick the best file type for each job, using the table on the file types page.
5. RGB or CMYK?
6. Transparency
A file that supports transparency can have an empty background, so a logo sits cleanly on any color. A file without it fills the empty area with a solid color, usually white.
Transparent background
The blue shows through around the star.
No transparency
A white box surrounds the star.
