without wanting to point you to the darkside but here's a good article
<http://www.microsoft.com/windowsxp/using/digitalphotography/expert/rawfiles.mspx>
Your camera is probably bundling 3 or more images in to the single
file - 1 the RAW data which is pretty much unique to each camera
model range/brand, 2: a standard TIFF image and 3: at least one
though probably more Thumbnails in TIFF or JPG format at different
resolutions.
I guess iphoto doesn't have the imager for that type of RAW file
and is only displaying the JPG or TIFF thumbnai lthat is part of the
RAW's metadata.
Graphics converter is probably stripping the RAW image out and only
keeping the TIFF image
Photoshop keeps the RAW data (and probably the original camera
generated TIFF) even after you save it - have you tried exporting or
coping it to a new Photoshop image? my guess is if you do this it
will discard the archived camera generated RAW and TIFF data. But
then you have to ask your self do you really want to discard such
information? and if so at what stage I've got friends who have been
professional photographers and the killer for them was the client who
wanted the colour balance changed in a photo 10 minutes before the
job go's to the printer or similar.
If I take a Nikon RAW file from my camera in NEF format it is 7.7
MB. If I open it and save it as a Photoshop file in .psd format
from Photoshop it saves as 28.5MB. If I do the same thing with
Graphic Converter it comes out at 3.8MB. If I open that file and
save it from Photoshop it drops back to 3MB!
Can anyone enlighten me please?

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.
