I want to print off my photos at a printer in town; I have the colour profile of the printer on my desktop. They only take photo’s in JPEG format. I usually save my photos, after editing, in JPEG on a USB drive, and take it in for printing.
1. How can I be sure that the JPEG image is 300 DPI? (I save it as JPEG in the original size; I assume that will be enough resolution for bigger prints; my original photo’s are all taken in RAW)
2. How can I incorporate the colour profile of the external printer, so that the JPEG images I see on my screen more closely resembles the final print?
