I am having the same problem. The one thing I seem to be hung up on now is that I have read that it can take 25 seconds to store the Hi-Resolution/Quality picture on the Coolpix 4500 (TIFF format, because RAW format not available as on the Canon S40).
The next step down seems to be equivalent to a 2 Mpel camera. What good is a 4 Mpel camera if I can't/don't use it at its maximum capability (at least occasionally) and a 25 second delay would certainly affect my use of the camera.
Does anybody use the max resolution mode. Is my undersanding about this correct.
