I have a photo that was taken with an SLR at 72 DPI JPG. I need it at 300 DPI for print, and at a much smaller size, so I changed the DPI in "image size" without resampling. Then I added the other elements needed for the mockup and had to change the size of the image using free transform. When I zoom in now the image becomes pixelated much earlier. Will this show up in print or am I just stupid and missing something?
