My question is a long the lines of the first post, with the exception that I am creating a 20x30 composite poster with an image as background, a baby picture smaller and blended in, and text. In the past, I opened a new document as a 20x30 and placed the embedded images and added text. Then output as a jpeg 10 or 8, but the PSD files were huge! Will it work just as well to open a new document as a 10x15 and for output crop as a 20x30? Thank you.
