I have this issue with Aperture 2 which I cannot seem to figure out... It seems like a bug but maybe I am doing something wrong. Ok, I download my raw files, prepare them and edit them and at some point I want to export them into 300 dpi jpeg to send to a printing facility. I have set the preset for image export on jpeg original on 300 dpi, but whatever I do it still gives me 72 dpi images. Now ofcourse I know I can change that in photoshop but that is just an extra step that I do not need. I've looked at anything I could think of but can't find a reason for this. It works fine when I export tiff in 300 dpi. It's just the jpeg that is refusing... Anyone has an idea?
