Okay, I have my lighting finally set up and got it all situated. I am going to have one of the Christmas greeting cards done this year of my kids. I am using MPIX. Do I need to take the pic in raw or jpeg, which one is going to look better? I have a rebel xsi. My problem is that I downloaded a pic to mpix and did the display but the pic looked really terrible. I have the camera set to 12 mgpixels. I am just trying to figure out how to have a clear, sharp picture on the 4x6 greeting card.
