I think this could be one of my problems as to why some of my images don't come out as good as I would like. Usually I will make an image to save just for printing to a specific size. I will usually run the res up to 200dpi, then adjust the size that I want the image to be printed.
Am I putting too much res in there? I guess my thinking is that more is better. Really need some help from those on here better versed than me. The main reason I am asking is that I plan on getting some post card backs from Photographers Edge and putting some of my images on to sell at a local store.
