Russ, I shoot at the highest jpg resolution also. When I bring my images into Photoshop, I go to Image>Image size and change them from a 72 to 300 which gives me a little over a 5x7 image. If I need to take a digital file to a larger size, I use Altamira Fractals. A 300 dpi digital print is a lovely thing. I print my own work on my Epson 900 and often I burn a cd full of images and have Costco print them out...4x6s for .19 cents and 5x7s for less than $2.00. Can't beat it.
