What size files do you give to customers for their printing purposes that are still high resolution? I use Lightroom and have my image size set at: "Resize to fit Megapixels", Megapixels set to 5.0, Resolution to 300 pixels per inch. I have used this sizing info and printed my own pictures just fine. I find myself having to instruct other people on how to crop pictures appropriately through whatever printer they are using. Is there a better size for more uniform printing? Less fuss for customers to print their own pictures. Do you do different sizes depending on depth of field? Not sure, new to me. Thanks!
