Why is everything pink?
I am very new at this so please bear with me.
I have a Canon Rebel t3 and when I try to import my pictures they all have a pinkish hue to them. I have looked at all the settings and they are all set to their default. So I went to UFRaw site to see if my camera was supported and it looks like it is not. I was told to download a DNG converter which I did, it was update 6.4. Unfortunately, when I try to open this it says "Update not applicable".

RE: Why is everything pink?
UFRaw uses DCRaw under the hood, and DCRaw supports the T3/1100D. Unfortunately you can't upgrade DCRaw independently and expect UFRaw to pick up the new version (other raw-processing software based on DCRaw will support independent updates of DCRaw).

UFRaw supports DNG, so yes, converting your CR2 to DNG should work.

On the other hand using a plug-in to import raw files directly in Gimp is a bad idea IMHO:
  • Gimp has an 8-bit/channel limit so using it for global color processing very quickly lead to artifacts.
  • This means you will have to do this work in the plugin, spending significant time there.
  • So you will want some kind of backup of what you have done there anyway
So a better workflow to process raw photos if to have a standalone raw processor, and use it to export a file that you can then feed to Gimp for some local changes. This file can be TIFF or JPEG. Your raw file processor will also usually save the settings used for the file so you can rework it later.
Since you have a Canon, you can use the DigitalPhotoProfessional (aka DPP) that came with it.
