DPI (dots per inch) refers to the resolution of your *printer*. You can't change it because it's fixed in the hardware. They're saying that you shouldn't use a printer with less than 720 dpi resolution. Your digital file *Output Resolution* is measured in PPI (pixels per inch). This is the value that you *can* set in Photoshop or whatever software you're using. If you're getting an 8 x 10 from a 15 megabyte file then you're outputting at less than 300 ppi. A 15 megabyte TIFF, output at 300 ppi, will yield a 6 x 9 (approx) print. At 720 ppi it will yield a 2.5 x 4 (approx) print. -- Mark Roberts www.robertstech.com - This message is from the Pentax-Discuss Mail List.
