ICC Profile: sRGB E. Output intent: Perceptual F. Output Depth: 8 (16 sometimes)

The above item, setting Output Depth, might be the problem with opening the TIFF files with GIMP. The latest GIMP releases just convert a 16 bit depth file to 8 bits, but earlier ones gave an error.

Also, the TIFF related stuff is in a library, used by both UFRAW and GIMP, so it if it is something else it may not actually be related to the specifics of either of these programs!

At any rate, try both 8 bit depth and 16 bit depth. Do that with two different images, one for each bit depth. If neither can be opened, see what this does:

bd
convert image1.tif -depth 8 newimage1.tif convert image2.tif -depth 8 newimage2.tif

That requires the ImageMagick package be installed. If it tells you there is no such command, you definitely want to download and install it! Great tool set for working with images.

Then try opening those with GIMP.

And if it still doesn't work, this almost certainly will:

bd
convert image1.tif -depth 8 -type truecolor -density 300 -units pixelsperinch newimage1.tif

Floyd L. Davidson
If that works, try it again without the "-density 300 -units pixelsperinch" options.
