How can I adjust to a higher resolution than 72 dpi for the Olympus SP-810UZ . Instruction Manual not very clear.

SOURCE: DPI

Have you looked at the number of inches that 72 dpi is spread out over? 72 dpi is the standard default setting for any digital camera. What matters is the size that you actually print it at.

Sounds like Photoshop's setting, or default setting, is to import picture at its maximum size. If you RESIZE pic on Photoshop, it shoud automatically increase DPI while reducing physical size.

The other thing to be aware, TZ3 defaults to a certain jpg compression. You can minimize compression of data with settings options on TZ3, but I doubt this has anything to do with your PhotoShop issue.

Also, in SIMPLE mode you can select a physical size for photo, even after pic is taken(resize), on camera.

Hopes this helps.

You can use a photo editing software on your computer to change the dpi, 

dpi has todo with printing and scaning dpi has no real change in the quality of your camera pictures

increase in dpi will not increase the resolution. dpi = dots per inch for example you have a res of 1024x768 at 72dpi you get a printed image of 14.2x10.6 inch at 300dpi you get a printed image of 3.4x2.5 inch
only thing possible is to interpolate the image. but thats **** in my opinion.

Hi!
If I remember it right, the resolution setting were under F button on the back panel, on the right from the Playback button.
Please, let me know if I'm right. :)
