ufraw ubuntu red is green

kjells · 03-25-2010, 09:05 AM

Dear All!
I recently bought a K-X and started to use it. I want to be able to import pef raw files to improve quality of my pictures. I am using GIMP 2.6 with a plugin gimp-ufraw under ubuntu karmic koala.

The problem is that the color profile is somehow upset, so that red becomes green. Is there something that can be done to correct this problem. Jpegs works fine and the camera is set to save files as raw+.

Best regards and thanks for any comment/kjell

The easiest way is to change your camera settings from pef to dng.

the gimp plugin does not handle pef properly.

For the once you already have in pef formate, you can run DNGConverter_5_6.exe from adobe in wine and convert the pef to dng.

It works fine on my wine in linux.

The version of UFraw included with Ubuntu (I think it's 0.16) does not support the K-7 and K-x PEF files. You need a newer version. 0.17 supports both fine. As mentioned above, shooting in DNG fixes the probem altogether since even old versions of UFraw support DNG files fully.

You can download the latest ufraw and compile it yourself.

Or just wait a month for Ubuntu 10.04 to be released. Hopefully the newer version of UFraw will be included.

I hate compiling stuff, especially on Ubuntu. All the supporting packages always end up being too old and they need to be upgraded before compilation is successful.

I prefer rawtherapee anyway. Much easier to upgrade.

Really? I have no trouble upgrading UFraw on a whim. I just don't use Ubuntu and everything works fine.

I have latest versions of both. Neither is perfect. I get jagged edges from rawtherapee and gimp doesn't read the exifs from the tiffs it exports. The noise reduction is excellent. Ufraw on the other hand doesn't do batch processing and for some reason I have to add a lot of saturation to get the same results I get from rawtherapee (default of quite unsaturated), but no jagged edges.

I only experience these problems with Nikon raw images. Rawtherapee was my choice with Pentax.

You realize of course that Gimp does not support EXIF tags in TIF files, right? It has nothing to do with rawtherapee.

Sure it does, I do it all the time. It's called ufraw-batch.

This has more to do with the linearity than saturation. The default linearity of UFraw is subtle. Try increasing the exposure by +1 EV and then increase the linearity slider from 0.100 to 0.300, you'll see some very nice differences.

Yes, I know. Looks like the progress with gimp here is quite slow.

That I didn't know. I'll try it out.

I'll try this as well.

Read the man page for ufraw

It mentions ufraw-batch near the top. But I agree that it is easily overlooked.

There's probably a PPA that lets you get the latest and greatest w/o compiling it yourself.

I might even be using it on my systems at home... need to check...

As suggested by David I switched saving images in dng format and that resolved the problem. I have also downloaded 0.16 version of Ufraw but the problem still occurs. Rawstudio has icon preview which I think is very good, although, a strange thing is that pef files icons are viewed correctly red is red and so forth, but the image itself has inverted colors or whatever it is. Red is blue or green...

In another forum, it is said that Ufraw 0.16 and 0.17 works fine on Pentax K-7 cameras. I have not found any report on its functionality on K-X.

0.16 works fine with my K-7. 0.17 isn't technically out yet.

Why don't the creators just compile these to an .exe file?
