I am new to photo editing. When I open a TIF file in GIMP created by Canon's Digital Photo Professional, I find that there are two pages that can be opened as either two images or as layers. When opened as layers, Page 1 is shown as a very small copy of the other Page and appears in the upper left-hand corner. What is Page 1, and what do I do with it?

It is an embedded thumbnail image, used by some image management applications to save loading that monster main image. Speeds navigation up.

Ignore it. If you have it as a layer, you can safely delete the layer. Otherwise do not open in the beginning. You can select the 'page' to use in the Gimp tif import dialogue.

Just to throw it out there into the universe: it would be great if GIMP offered an "open the analogous TIFF page for remaining files" checkbox... e.g. when I open 45 such TIFF's as layers I have to click through 45 dialogs to get the 'real' image for each layer. (One can of course automate this extraction with the command line as well.) Or a prefs setting to default to opening the largest page, or similar.

(It would also be great if Canon DPP had a "don't save thumbnail" on export, of course, but that's a different and much less helpful mailing list. :-) )

Thanks, Rich.

It is also be for a different mailing list/forum, but there are good, free, and Gimpp-friendly alternatives to Canon DPP, such as RawTherapee or Darktable :-)

Thank you! Yes, I'm aware of and love (and use, and prefer) both of those programs... but DPP has the "digital lens optimizer" which seems to do some specific magic thing (presumably with proprietary/protected manufacturer knowledge of their lenses) that I can't seem to duplicate in other software (including lightroom, capture one, etc.). It's not always good to use it, but often it is. But I get closer every day to abandoning it.

Anyway, like you say, different mailing list. Thanks, -c
