Raw Processing in Gimp 2.6.11
After installing the Gimp 2.6.11 Tiger PPC, I want to know if Raw Processing is available on this Gimp version. If so, after opening a raw file in the Gimp, how can I access the Raw processing tools? Thanks, Ken.

RE: Raw Processing in Gimp 2.6.11
Out of the box Gimp does not have the ability to handle RAW files. There is however, a plugin called UFRaw that adds the tools necessary. I was just looking at their web site and in the area for Mac downloads it says that the Gimp application bundle from Gimp on OS X (which I believe is what you used) comes with UFRaw already installed.

I'm afraid I've never done any work with RAW files, or used UFRaw myself so I can't be of much help with how to access or use the tools. I would recommend the User Guide on UFRaw's web site as a good starting point though.

UFRaw works as a file access plugin. If is installed and properly configured, Gimp is associated with the file extensions for raw files (.raw, .cr2, .nef, .dng....) and calls UFRaw to decode the files when you ask it to open them. At that point, instead of quietly decoding directly the file like the file-jpeg or file-png plugins, the UFRaw plugin opens its window.

RE: Raw Processing in Gimp 2.6.11
Ofnuts, on my first boot up of the Gimp, which takes the longest, I saw UFraw go by as one of the Gimp plugins, so what I am gathering from your reply is that when I open a RAW file in the Gimp, a RAW processing set of tools will appear for me to work with. I am using an Olympus EI, which allows raw + raw+jpeg photography. I also have the Olympus software that came with the camera which has a very extensive, fully compatible set of raw processing tools (might be the best of all). Also iPhoto also has raw tools. Just want to see which way to go, have never shot any raw photos, just want to settle on the top set of tools. I suspect that the Olympus software will be the best because it exactly works with the camera.

By the way Ofnuts, thanks again for your input on installing 2.6.11, not 2.4.7 Tiger PPC. The install went perfectly, I think the 2.6.11 even runs faster on my legacy iMac G4. You probably know this but I was able to extract the extract the Help file, so that I can learn about the Gimp without launching the program. I went to "User/Library/Applications/Gimp/help". I then open the Help folder, locate the "index.html" icon, make a "alias" shortcut to a convenient location, then right click on it, select "open with" then "Help Viewer", the Help software on the Mac, not the browser. The same content listing appears except with a larger, more legible font, like having an electronic print manual (can even print the occasional page from it). Hope this helps. Ken.

RE: Raw Processing in Gimp 2.6.11
If the software came with the camera, and the camera is an E1 (I don't know about any "EI") then it's fairly outdated Smile

The camera manufacturer's raw decoder usually does the job, but may not have too many general options (algorithms used for dematrixing, denoising, sharpening) unless it's an extra expensive version, such as Nikon Capture, while it may have some functionalities hard to find elsewhere (show active AF point, for instance). It will also often be able to apply very accurate corrections things (lens distorsion, vignetting) using data in the EXIFs, but this will be limited to the manufacturers products (lenses). Given the scant availability of OEM lenses for Olympus cameras, this may not be a problem Angel

On the other hand generic decoders have more choices and can do a good job at correcting lenses (at least those that use the lensfun library and database, such as UFRaw).

I don't see much purpose in using iPhoto, unless you use only iPhoto, because its raw capabilities will likely not match those of specialized decoders.

Another consideration for your software choice is the support you can get from the community. (Apple market share) x ( Olympus market share) x (ratio of people using the Olympus software) x (People using raw) is not going to make that many people (even if we know it's at least oneSmile.

RE: Raw Processing in Gimp 2.6.11
Thanks Ofnuts for your informative reply. The Olympus E1 is circa 2004, the first actual, made from scratch professional dslr, in the 4/3 format, with its own specific lenses. Olympus Studio originally cost $150.00 but is now free (email Olympus for the software + Serial number link) with all the raw functionality you mention + much more. I am in active contact with the Olympus community forum, check out much research, consensus being that Studio 2 is best for Raw. Being new to digital (still a film shooter), not of the computer generation, I am open to trying a variety of solutions. My learning continues. Thanks again, Ken.
