I've never printed anything large so I am totally new to this. I have credit at Shutterfly and thinking of ordering either 20x30 (preferred) or 20x16 print. The picture was taken with E-PM1 at base ISO and it is well exposed and pixel sharp as viewed at 100% and it's RAW.. I probably still need to crop it to match 20x30 frame and there isn't enough MP for 300dpi print. I don't see any LR profiles on Shutterfly website, only mention that Fuji Crystal paper is used. Any idea how to best prepare the image for printing and whether I should do 16x20 for better result and less cropping vs 20x30?
