dlRaw update

Posted Tue, 22/09/2009 - 23:52 by mike

Hi folks,

here is the next dlRaw-preview update. It doesn't include the things I thought about last time (I'm still working on that) but it includes the last work of Jos. He has offered an update to the current dcraw in SVN trunk. So this will allow people with newer cameras to use dlRaw. I also worked in some other changes of the current trunk version, but the flexible pipe is still only there. Enjoy Wink

You can get the update here.

dlRaw: make some noise

Posted Fri, 11/09/2009 - 20:08 by mike

Hi folks,

finally an update for dlRaw-preview and right before the weekend to give you enough time for testing and working with it Laughing out loud

What's new? Besides some small changes we have:

  • There is a new posibility to simulate film grain.
  • Normalization was added.
  • The multithreading code contributed to the mailing list was implemented, not much, but a starting point Wink
  • The windows version is now also built with multithreading and it looks better now.

Recently I compared with UFRaw, and there is a remarkable difference in the output, concerning the distribution of values. I cannot judge which one is theoretically correct (this work in dlRaw was done from Jos), but I'll try to get some answers for this. Would be nice to know what you think about the different results. For the next release I'll plan to have the basecurve back, easier gimp integration on windows and saving in more file formats.

As always the download link.

So have fun with it, and leave feedback Wink

dlRaw: still alive

Posted Sat, 05/09/2009 - 01:14 by mike

Hi folks,

I wanted to let you know, that after the summer break dlRaw is still alive Wink Recently we got a nice contribution in the mailing list, it adds basic multithreading to dlRaw. So now AHD demosaicing and histogram generation are parallelized. It's not much, but a first step, and hopefully more steps are following. But the disadvantage was, it took me many evenings to get it compiled on windows. Another compiler has to be used, but for this compiler no qt4 binaries are available and so the story started... But hey, it's done Laughing out loud Actually I think it's not enough to post a new version, but now regular development can proceed.

Furthermore I started to post some more information and screenshots of dlRaw-preview, so feel free to have a look.

Hopefully we have some new features with the next blog post, stay tuned Wink

dlRaw: new local contrast

Posted Fri, 31/07/2009 - 21:51 by mike

Hi folks,

I know, it really took some time, but finally I can offer a new local contrast filter in dlRaw preview. It is modelled after this very nice gimp plugin and should give a similar result. However to improve the speed the implementation is not completely rigorous, but this shouldn't effect the quality. You can find it in the LAB tab as local contrast stretch.
