I found an illustrator for a picture book. Unfortunately, she has never worked in ebooks. Where do I find information on type of paper to use for an illustration, how to get the illustration into a file for conversion (just scan??), etc. Thanks.
Scan them in and touch them up in Photoshop. You may need to color correct or get rid of scanning artifacts. And sometimes if the artwork is glossy, it won’t scan quite right. Let me know when you get them.
