First Question:

When I process a Canon RAW (.CR2) file in Canon's Digital Photo Professional software, I can convert and save it as a few different formats. The choices are...
Exif-JPEG
Exif-TIFF 8bit
TIFF 16bit

To me it seems to imply that the Exif data will get written to the file for the first 2 choices, but not the last. Is that right, you can have Exif data in TIFF files, just like JPG? However, I don't see any Exif data in the Exif-TIFF 8bit file it generates, just in the Exif-JPEG. Maybe the programs I am using (DigiKam and Gimp) just don't understand Exif TIFF.

Second Question:

When I convert and save to TIFF, there are 2 parameters I can set. The first one is output resolution - which defaults to 350 dpi. What effect does this have, and what should it be set to? The second is a checkbox to "Embed ICC Profile in image". What should I do with this. It defaults to ON.

When I import these files into Gimp, it sees 2 'pages'. I can import both - and one of the seems to be a thumbnail image, the other is the full res image. Is this normal?
