I started using my first digital camera (Canon dRebel) about a month ago, and there are still things I don't understand. Here's one: I shoot in RAW. When I get the image into PS Elements, it's a TIFF file, and the image size is a huge 21x32 inches. This size is too large for me to print. Actually, the only print sizes I want are 4x6, 5x7, & 8x10. To get, say, a 4x6, I assume that I have to resize the image. But when I resize, the image loses its sharpness and its diagonal staight lines take on jagged edges as though the lines were made of tiny building blocks. I've tried resharpening the image with PSE's Unsharp Mask &/or Sharpen or Sharpen Edges. But then the resized image never looks as good as the original image, and sometimes it looks somewhat unrealistic and I hate that. And the diagonal lines never do get straight again, no matter what I try. I'm getting discouraged and think I need some help. Am I doing something wrong? What is the best PSE tool for resharpening a resized image? Should I stop shooting in RAW ( I never shot in JPEG, so I don't know what size image that makes on my camera).
