Hi folks,

here are some more photos of our short trip to the Baltic Sea. These are all from the Olympus E-P1, and completely processed with dlRaw-preview.

Have fun, mike

dlRaw and auto contrast

Posted Sat, 10/10/2009 - 00:08 by mike

Hi folks,

so in the background Jos and I are discussing how to handle the contrast problem... which contrast problem? Wink Well when you open a RAW file without any filters it looks dull... When doing the same in UFRaw it looks contrasty... Of course we want a pleasing starting point for the processing so what to do?

When looking at the code, dlRaw seems to handle the gamma applied during all the conversions more "consistent" than UFRaw. At least I don't understand completely their procedure... But the drawback for dlRaw are dull images without any filter applied... We haven't settled this question for dlRaw completely, but after numerous tests I have now a RGB curve, which should do the trick... I have attached the file to this post, so just put it in your curves directory and set it as RGB curve in dlRaw... I could only test it with RAW files from my cameras, so please test with yours and leave feedback.

dlRaw got a wiki

Posted Wed, 07/10/2009 - 23:30 by mike

Hi folks,

so it seems dlRaw gets important (at least kind of Wink ), there is now our own wiki for it. Of course we plan to fill it with the needed documentation for dlRaw, but this will be tedious work... Otherwise merging of the two versions is in progress and some issues about the background of the processing are discussed. So work as usual Wink

Hi folks,

we had a small vacation at the Baltic Sea, of course with lots of photos... But even with dlRaw processing needs some time, so here are the first three impressions from the first evening in Warnemünde...

dlRaw: behind the scenes

Posted Mon, 28/09/2009 - 23:41 by mike

Hi folks,

I just wanted to tell you what we're doing in the background. So after a long summer break development is active again and the point of merging the two versions comes closer. For this the SVN version is prepared by Jos to allow good usability even with many filters in the 'pseudo-static' pipe.

What should 'pseudo-static' mean? So in the background the pipe is flexible now, you can alter the number and order of the filters, but at the moment not at runtime. This allows everyone to have it's own pipe, with only the wanted filters. Now it will be your choice if dlRaw is very fast and does only the basic steps of the RAW workflow or if it is packed with a lot of creative filters to have your complete workflow in dlRaw.

The plan for the future will then be, to have a new (or enlarged) GUI to allow reordering of the filters at runtime for full flexibility... This should then also give the possibility to have presets and settings files for the pictures, so that you can easily reproduce the workflow of one image on many, or only parts of it, e.g. a special denoising workflow or a B&W conversion with toning and grain simulation workflow.

Meanwhile stay tuned, and have fun with the available packages Wink
