Image Quality and DPI on the Z10?
Does anybody have any insight as to what the default dpi of an image taken on the Z10 will be? I enlarge photos and print them on canvas at work, and images have to be 300dpi to meet print quality. People send us pictures from phones that look ok on their screen, however when you blow it up, they suck. People don't understand that because it looks good on their tiny screen, it doesn't mean it will look good enlarged. The phones we have tested, (Galaxy S3, iPhone5, HTC One Hero, etc.) all of them have a default setting of 72dpi when imported to a computer. 72dpi is all the better a monitor can display, but 300dpi is the standard print quality throughout the industry. Can anyone with a Dev Alpha import a photo from the device, into Photoshop and tell me the image size and dpi quality?

For example, a 300 DPI photo that's an inch by an inch isn't going to be blown up and printed as a 24" by 24" wall poster. Likewise, you can probably get a pretty awesome 4 x 6 print out of a photo that's 8192 x 6144 @ 72 DPI.

72 vs 300dpi doesn't work that way in digital imaging. You need to be concerned with PPI. An image, short of resizing it, will only ever have an amount of pixels equal to the resolution. Say you had an 8mp image that is 2448x3264. Photoshop by default will load that in at 72ppi. The resulted printed image at 72ppi is a 34x45 image of obviously poor quality. If you wanted an image at 300dpi it would be 8x10 you can't just make more dots than there are pixels. The dpi shown in PhotoShop is irrelevant. If you want more you need to resample up.

I understand you can't just make more pixels, it does to work that way. And yes, you can have a great quality print out at 72dpi if the image is small in dimension. Your average Digital SLR camera takes an image that when opened up in photoshop, or any other photo software, is already at 300dpi. All I want to know is what the dimensions and dpi are of an unedited picture from a dev alpha. Otherwise I will just wait until I can buy a Z10 and check it out myself. Thanks though.

the dpi o fthe image i dont know, although i can definitley say previous posters saying 356dpi are talking about the screen not the image created by the camera.
also note in 16:9 (full screen image) you`ll get about a 6mp photo
