The Coolpix 4500 offers a wide variety of resolution and image format options. You can choose from JPEG (three compression levels) or TIFF at 2272 x 1704 (full native resolution). JPEG image sizes are 2272 x 1704, 2272 x 1520 (3:2 aspect ratio), 1600 x 1200, 1280 x 960, 1024 x 768 and 640 x 480.
To give an impression of what some of the combinations of image size and quality produce the table below is a cross reference of some of them:

The majority of purposes there is very little visible difference between JPEG Fine and TIFF mode. I don't expect many 4500 owners to be using TIFF, but if it weren't there we'd certainly see a lot of people asking for it! After that there is a slight degradation in quality using the Normal setting and a very visible degradation at Basic. The lower image sizes will of course have that crisp sharp look although I was a little disappointed that 640 x 480 JPEG Fine had as many visible JPEG artifacts as it does.
