A second option is to get used to Picture Styles on the camera. You can set up a custom style with increased sharpness, contrast and saturation levels all in-camera. The best thing for anyone new to the DSLR world to do is read the instruction manual. When I got into DSLR photography, I read the manual of my XTi front to back.

But the greatest tip of all: Just keep shooting.
