[QUOTE="aroy, post: 550464, member: 16090"] The printed pixel density will determine details on a print. For close scrutiny (coffee book) 300DPI is minimum, while for hanging prints viewed at 2-3 feet, 150DPI would suffice posters visible from 10+ feet can get away with 50DPI while billboards are fine at 10DPI. RAW, JPEG or TIFF files will have the same number of pixels, so as far as print resolution is concerned they should yeald the same result. Next comes the colour depth, that is colour shades. JPEG have 8 bits per colour, while RAW (and TIFF derived from RAW) varies from 12 to 16 depending on body, so the colour depth will definitely depend on the number of bits. This colour depth will also depend on the printer and most printers used by commercial houses have 8 bits (or less) colour depth. There are few high end printers which can give 10 bits. If the printer can print at 10 bit colour or more, then the image will benefit from TIFF 16 bit file, else 8 bit JPEG is enough. [/QUOTE]
