72 dpi?

Ok. Maybe I just need to read the manual a little harder, but I can't seem to figure it out. I tried different formats and quality settings, but I can't get my FZ15 to switch to anything higher than 72 dpi. Right now, the photos are like 32x24. I would rather have a much smaller photo, but higher resolution. Am I stupid?

It is not the camera, it is the program your using to view the photos , but there is nothing wrong with that as that is the best the monitor can see.
But most viewing programs have a fit to window or some such setting to allow you to view it at normal size.

For instance if your viewing in XP with Window P&F viewer there is a best fit and a actual size button along the bottom.

I'm using Photoshop 7. Other lower-end cameras have shown up as 230 dpi or 300, and I was wondering why my pictures were HUGE and lower res.

Basic JPEG images do not contain data space to record a prefered PPI. When encountering images without a specified PPI, Photoshop defaults to 72ppi. This is the common default used by most graphic arts applications.

TIFF, on the other hand, supports this concept (in fact, the idea was invented for the original v1.0 TIFF spec). Some cameras, like my old Nikon CP950, spec their TIFFs at 300ppi and Photoshop reads that in the files' headers and opens them accordingly.

The PPI recorded in a file has absolutely nothing to do with quality. It is mearly a "crib note" attached to the file telling the app that opens the file how to map the pixels. When the app lacks a concept of a virtual inch, they ignor the spec and map the pixels however they want. This is usally a 1:1 pixel for pixel mapping for apps that simply display the images onscreen. It is sometimes an automatic "fit to screen". Either way, its something the app decides and cannot be controled from the camera.

In Photoshop 7, if you resize the picture smaller, the default is "resample image" which reduces file size and keeps the DPI at 72. If you uncheck the "Resample Image" box when you reduce the picture size, the file size stays the same so the DPI will go up.
