I have just passed a photography course with the Open University and am setting up a website to sell my pictures on. Instead of me printing different size photos and having to send them to customers I want to make them downloadable so the customer can then get the photo printed to whatever size they want on paper or canvas. My problem is that I don't know what size in pixels to save the images as so that the pictures can be printed at small or large sizes and also what format to save it as e.g. jpg. I was told by someone that it would have to be saved as an editible pdf for all printers to change the size but I'm not sure if this is correct. Also, all my pictures have my name as copyright in the EXIF data, will this be a problem if customers want to get the pictures printed somewhere like Klick or Tesco? I hope someone can help me as I'm tearing my hair out over this.:bang:
