[QUOTE="WayneF, post: 475183, member: 12496"] You have to realize that the image and the paper are [B]not the same shape[/B]. Sort of like a square peg in a round hole. :) Tbe DSLR camera takes pictures that are of shape 3:2 (long side is 1.5x the short side, which is called aspect ratio). This will print on 6x4 paper as is, which is the same 3:2 shape. But no matter what SIZE you enlarge to, the uncropped image SHAPE is 3:2. But 5x7 or 8x10 paper are not the same shape. 5x7 is shape 5:7 (long side is 1.4x the short side). 8x10 is shape 4:5 (long side is 1.25x the short side). These are shapes. The 3:2 image is sort of long and narrow, but many paper sizes are more short and wide. So yes, a 5x7 will have to crop of about 1/2 inch at one end, or 1/4 inch at both ends, something like that. An 8x10 will have to crop off about 2 inches. Or a 4x6 will print it as is (this might be your best answer?) Uncropped 3:2 images will enlarge to be 5 x 7.5 inches, or 8x12 inches, which does not fit the 5x7 or 8x10 papers. Or alternately, you could keep the long end intact, and print it 4.67 x 7 inches (0.33 white border on one side, which can be trimmed off). However, this is a very special deal at most photofinishers, many of them will not do it (will fill all the paper regardless), UNLESS you actually edit it to add the blank white strip into the full picture size. It is exactly like the problem of trying to print 4x6 on 4x5 paper. Simply Not the same shape. Printing photos has ALWAYS been like that, for at least 100 years. :) Film and paper not the same shape either. And also different size print papers are also not the same shape. It is good when shooting the picture to keep in mind the thought about fitting it to a specific paper size, and maybe leave a little cropping margin around it. So first we have to crop the image to be the correct [B]shape[/B] to match the paper, and then we have to resample it to be the same [B]size[/B] as the paper. Again, [URL="http://www.scantips.com/lights/resize.html"]Image Resize - Cropping, Resampling, Scaling[/URL] is about this subject, shows how, etc. [/QUOTE]
