I guess you have noise reduction enabled. Just set threshold to zero.

Thanks.

What are you comparing to? JPEGs produced by the same camera? If you use RAW, many enhancements that your camera normally does are not done, among them sharpening. Depending on your camera you might have a setting in your camera to select how much sharpening is done on processed images.

You can use either the Sharpen filter or Unsharp mask to sharpen your imported RAW photo in GIMP.

I am comparing to my very similar workflow from within XP (as compared to Ubuntu). The difference in XP is that I first open my imaging using Sony's Image Data Converter that came with the camera. That application does a beautiful job of minimizing noise (even from ISO 6400 images). Then, I either use CS4 or Gimp to open the file as a tiff. I never shoot using anything other than RAW.

In Linux, my only converter options are UFRAW or Lightzone (which I have stopped using of late). I cannot even find the noise reduction tool in the Linux version of UFRaw (not certain there is one). I've used UFRaw in Windows, and there is most definitely a noise reduction tool, and I was, frankly, surprised at what a good job it did.

I know I must have changed some setting that persists in UFRaw from one session to the next, but doggone if I can figure out what it is.

Any additional suggestions most welcome. Thanks for the replies.

Just so you know.... Noise Ninga is available on the Noise Ninga site (picturecode.com) in rpm and deb packages. It's proprietary, but seems to work fairly well after you take the time to set it up correctly. You can try it out for free, but must buy a license to save anything you want to keep as the demo puts a grid over the top of the picture.

When UFRaw opens on my machine towards the bottom of the panel, on the left hand side, there is 'Denoise' with a slider, isn't this to remove noise? I am using Ubuntu 8.10.

Noise Ninja works very well -- for some things. For outdoor "nature" shots, it works too well. Reducing noise takes the detail out of natural textures like snow, water, forests and ground cover.

Noise Ninja makes great skys and clouds though. But you have to fiddle to get the rest of the detail back using the un-noise brush.

But Noise Ninja is a real handy tool.

On Windows, I can go to GIMP\bin and type ufraw-batch in a Dos command window. I can also type ufraw -help and that brings up a large window full of options -- that unfortunately goes off the bottom of my screen so I can't read the whole thing.

I found that if I save the configuration in ufraw, that the next file that opens uses that configuration. However, I shoot portrate mode for my panoramas and so I have to manually rotate each image as it is loaded. The configuration does not seem to save that instruction.

I found out that ufraw-batch takes an ID file. But I do not know the format of the ID file or how one might generate one.

I googled around for ufraw id files and found this:

http://osp.wikidot.com/tutorials

But this page -- which is has the UFRaw tutorial doesn't exist.

http://serge.mankovski.com/photoblog/raw-processing-in-gimp/

Perhaps you can point me in the right direction again...

Why don't you have a look at http://ufraw.sourceforge.net/Guide.html there is a reference there to batch processing using ufraw-batch? Sometimes having a look around saves a lot of time and agro.
