Am trying to use the RAW converter for the first time, on CR2 files I just import from my EOD 450D, but the RAW converter batch tool doesn't seem to be active. When I select one or several CR2 photos, the Outils -> Convertisseur d'image RAW remains inactive.

Seems to work after trying to upgrade to 1.4.0 Digikam version then reversing to 1.2.0 version.
I know need to learn how to use it. Is there some documentation available somewhere, considering I'm a complete newbie in RAW processing?

Thanks for your answer, but it's the Digikam procedure I'm stuck with.
When trying to edit a raw picture: - no function in the first tab ("Décodage brut" in french) seems to modify the picture ... or the preview reflects no change, - second tab ("Post-traitement" in french) functions do modify the preview, but there is no save options available!? So I don't understand how to proceed to make some adjustement before saving my picture. Thanks for any idea. 2010/9/7 Darren Kirby <[hidden email]>

In the digikam raw converter, the first tab has a button 'update' which applies the changes you made. No direct update, as the conversion can take quite some time, especially when you select the option to rebuild the highlights. (I think this is because a number of changes has to be applied before the matrix interpolation and to the full image data) The post-processing tab only has actions that are relatively fast so direct preview is possible (also because the modifications can be done on the preview image) To get the image in the image editor, use the 'import', this will generate the full image and open it in the image editor, where you can finish adjusting it and save it (at the very least I apply some sharpening before saving, and perspective or lens corrections, cropping if needed, etc.) Hope this helps Remco _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

Great, that helps a lot! Now, I can begin to "play" with it. Thank a lot for your answer. Marie-Noëlle -- Une galerie photos, un blog ... pourquoi pas ?

Download is this link: http://meetthegimp.org/torrents/meetthegimp001.mp4 It's in the top of the window, right below the title like "Episode 001: Preparing an image for the web". My mplayer thinks it's a DivX (mpeg4) video with AAC audio, and plays it fine.

The link for Episode 11 is completely different :
http://meetthegimp.org/wp-content/uploads//meetthegimp011.mp4 and it doesn't work. Using the URL you've provided, and changing the episode number, I'm now able to download and play the video. Thanks a lot for helping, Marie-Noëlle 2010/9/26 Gerben Roest <[hidden email]>

This has helped a lot to understand how it works. However, as a complete newbie to raw, I feel very handicapped at not seeing immediately the results of every modification. For white balance for example, sliding cursors back and forth has no meaning for me if I can't preview the resulting effect on the image. Lack of documentation is also an issue. I'm really willing to switch from jpeg to raw, but I'm still struggling to get some result. Thanks to those who have directed me to the "Meet the Gimp" videos, I think I'll give a try to the Gimp ufraw plugin, that seems much more easy to use (wysiwyg at least). But I find another way, or more accessible documentation, I'll be happy to go back to Digikam to do the raw treatment. Marie-Noëlle -- Une galerie photos, un blog ... pourquoi pas ?

And, by the way, ufraw is able to store the settings you made in a seperate file. So if you want to change some settings, like whitebalance, curve adjustment or similar, you can open the ufraw config file and change the settings. You don't have to start from scratch. > > But I find another way, or more accessible documentation, I'll be happy > to go back to Digikam to do the raw treatment. I use ufraw/gimp combo to edit the photos and digikam to manage and preview them.

That is true, and that is why I am not using digikam to convert raw files. In addition to the gimp plugin mentioned you may also want to check out rawtherapee and also ufraw is available as a standalone program. After trying all three I have settled on rawtherapee for raw conversions. My workflow is essentially: raw -> rawtherapee -> 16 bit tiff -> digikam -> 8 bit jpg. To elaborate: I initially import all raw files into digikam, but use rawtherapee for conversion and WB/exposure adjustments. I save as 16 bit tiff for further editing within digikam, then export to 8 bit jpg for publishing to flickr. Perhaps more work, but I am very happy with the results.

Martin and Darren, thank you for your feedback.
Considering I'm a complete newbie on the matter, I'm much more comfortable knowing I'm not alone having some problem with the raw treatment in Digikam. Hopefully, it will be improved in a future release. Marie-Noëlle -- Une galerie photos, un blog ... pourquoi pas ?

I have a question for those who use ufraw or another non-proprietary tool: have you found the icc files for your camera, or do you use the DNG converter provided by Digikam?
I've found a lot of icc files on the Canon CD, but I don't know which ones I must use for the EOS 450D. So if you have any hint or advice ...

Jep, I found the icc files and I used them for testing and for one shooting. I don't use the DNG converter as this brings horrible results from my cr2 files. I test it every now and then, but the white balance as well as the exposure is a total mess. I tried Adobes DNG converter as well (on my windows VirtualBox). The results are much better but not as good as the original raws. > > I've found a lot of icc files on the Canon CD, but I don't know > which ones I must use for the EOS 450D. If you really want to take the step into colour management throw away the canon icc files. The results are not as good as the default ufraw color-matrix. Only in some strange highlight situations they are better. Default icc files for a camera are not a good idea. Either you calibrate and profile your camera under the circumstances you use it or the main benefit of colour management - getting a well defined reproduction of the colour - is not guaranteed. BTW: then you have to go the next step and have to calibrate and profile your monitor, scanner and printer as well. And you no longer can use the cheap photo labs as they don't care about colour management. I bought me an IT8 target for the camera and the scanner and a colorimeter to set my monitor (a cheap spyder 2) to have an almost calibrated environment. With the IT8 target I create icc files for my camera myself and at least with ufraw they are working. With the digikam raw converter the results are crap - so as I don't use it I can live with this. And to my own icc files: I am not always satisfied with them. It is not that easy to take a good picture which is usable for calibrating and profiling. > > So if you have any hint or advice ... > > Thanks, > Marie-Noëlle Martin _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

... Thank you very much for your anwer and all the explanations. I will try to keep things simple though, as I only take very amateurish pictures to publish them online (and obviously very few visitors have calibrated screens). I just want to "upgrade" from the standard JPEG to something a bit better, that allows me to do some modifications on the computer after shooting (white balance, exposure, etc.) RAW treatment is entirely new for me (and I'm not very experienced at photos too) and I'm struggling to get the basics working. So your help has been very much appreciated. Marie-Noëlle -- Une galerie photos, un blog ... pourquoi pas ?

This is one part. The other is that not even all browsers out there are able to handle colour profiles. > I just want to "upgrade" from the standard JPEG to something a bit > better, that allows me to do some modifications on the computer after > shooting (white balance, exposure, etc.) If you realy want to do stuff like white balance, think about calibrating and profiling your monitor (at least).
