Good morning, The platform I'm working on is Windows 10, when I export TIFF files from NX2, I simply put them in a folder on the hard drive under Pictures. I then use Windows file manager to organise them. I've tried right clicking and using the "open with" option, but GIMP is not an available

I've just tried converting a file from jpg to tiff with ViewNX V2.10.3. When opening in GIMP I get an error message about a null byte in the date field but it then opens the file as two layers with the top (active) layer being the thumbnail exactly as you said. Looks like this is a bug in

Where are the TIFF images stored? What platform are you working on? Can you right-click on a TIFF image in the computer’s directory window and select “Open with…”? That’s how I open most images with GIMP. The import functions are handled by GIMP, and I tend to use the defaults. Haven’t noticed

Good morning all, The image I was working on was created by Nikon's ViewNX2 editor, the original image format was Nikon's raw image .NEF extension, I exported this as a TIFF and then imported it to GIMP. In ViewNX2 the images are stored with a preview thumbnail, so I think you have hit the nail

When I open (I don't see an Import option) a tiff file I don't get asked whether I want to open it as layers. This was a file that I exported as tiff from GIMP. Which program was used to save the tiff file that you are opening? Could it have saved the thumbnail as a separate layer rather than as

I'm trying to use the GIMP channel mixer to reverse the red and green channels in a TIF image. I'm using GIMP 2.9.6. After swapping the channels etc. and hitting OK, all that happens is that a very small thumbnail appears in the top left corner of the main image. I can see that the channels have
