schatzoy Posted October 29, 2006 Share #1 Posted October 29, 2006 Advertisement (gone after registration) I am totally confused. I used to shoot with a Canon Powershot S45 (4 MP). When looking at the pics in Photoshop Elements 5.0 the status bar tells me 180 ppi. Now I have a D-Lux 3 and the status bar tells me 72 ppi only. It's the same story with ACDSee 9.0, the Exif clearly reads 180ppi (S45) vs 72ppi (D-Lux 3). What's happening here? Why am I not getting a higher resolution? Can anyone shed some light? Thanks.

dorman Posted October 29, 2006 Share #2 Posted October 29, 2006 Your camera resolution is only determined by the number of pixels you have. Likewise when you view on your monitor it is the pixels that count. The ppi makes no difference. The ppi number only serves to tell the printer what size to make your print. If you picture is 3568x2368 pixels and you set the ppi to 100 and print, your print will be 35.86inces wide. If you set to 300ppi, it will be just under 12inches wide. You can quite acceptable prints from 150ppi upwards, with best quality coming from 300ppi. The ppi your camera attaches to the file is arbitrary.

schatzoy Posted October 29, 2006 Author Share #3 Posted October 29, 2006 Thank you dorman for the explanation. Well, this ppi and dpi got me all confused. Specially since the 4MP of my old Canon look better on the monitor than the D-Lux 3 pics. They look somehow washed out (using flash indoors). For comparison I made a pic in RAW and this shows 240 ppi resolution. I will do a test print 6x4 and see what's the result. Hope it will look better than on the monitor.

neils Posted October 29, 2006 Share #4 Posted October 29, 2006 I was about to post a very similar question. If I shoot in RAW, look at the file size in CS2 I see 240 ppi. In every possible JPG image verson and size the camera can shoot I see 72ppi and a HUGE image size. Sometimes I would like to shoot the biggest/best JPG but make a print. Does it make sense to change the 72ppi to 240 or 300? Seems like it would wreck the quality somehow. I haven't tried it yet. I would have though I'd get a JPG the same ppi as the RAW as my Nikon DSLR does in best quality. Neil Link to post Share on other sites More sharing options...

Neil As stated above, ppi is unrelated to actual number of pixels--it only relates to how those pixels are spread out. 72ppi is typically monitor resolution. 300ppi is typically the resolution for commercial printing. No image is gained or lost when you adjust ppi, UNLESS you resample the image when you reset the ppi. Then you either lose image or create inaccurate, interpolated extra image. Dpi (dots per inch) is more properly used to discuss output (laser, inkjet or commercial printing). Link to post Share on other sites More sharing options...
