Incidentally, iPhoto will happily accept these files from the camera and export them as TIFFS. However, only the thumbnail is available within iPhoto so they will not enlarge properly in iPhoto.

sorry missed this last point - to ACTUALLY use and take advantage of the RAW format to any extent at all you have to use a program that USES the RAW data and not the appended TIFF - Photoshop can't deal with RAW data in any way and just ignores (but keeps) it as file meta-data (unless Photoshop CS now includes it) such a program would have come on a CD with your camera or there are several other ones that will do the job as well if not better.

In the end I selected a camera that doesn't do RAW images so the pre purchase research is all I know about actually using RAW data in post processing

There was a recent discussion of image formats in part III of Beyond MegaPixels

Might be interesting to some.

Have fun,
