Creating drop shadow and glow effects in Photoshop while keeping the vector art in Illustrator
If you are unfamiliar or a little unclear about the differences between vector and bitmap art, it might be helpful to read When Vector Art is Really Vector before starting this tutorial.
Setting Up Your Files
Start by determining your art board size. If I am working on a wide format project I like to work in quarter scale. Illustrator has a maximum canvas size of 227 inches, so projects larger than that have to be created at a smaller scale factor. See Large File Format File Resolution for a guide to scale factors and resolutions.
