Luminance HDR 2.0.1

After a long search, I’ve found what the error in LuminanceHDR was. And I fixed it!
Currently, the new 2.0.1 is just a general fix of the TM operators. This will make the output exactly equivalent to the one we used to have with qtpfsgui 1.9.3 (in some cases, even better).
This release includes the first Mac OS X edition of the 2.0.X branch and I expect a lot of feedback on it! A Windows version will be available soon (hopefully Giuseppe will make it for us soon). Obviously, for the Linux huggers, source code is ready for you to be compiled.

My plan for the future releases is:

  • go thru the bugs still open on the Tracker and try to fix as much as I can;
  • improve the Mac OS X build, using Apple libraries wherever it is possible, in order to improve throughput and overall user experience;
  • improve memory management, in order to avoid unneeded swap and crashes;
  • improve the user interface, trying to make it more understandable for the average user.

I would like to say thank you to Axel Voitier (patch on a critical race in the Mantiuk06 operator) and Elizabeth Oldham (patch that enables or disables UI features). Their help made LuminanceHDR better.

For a reason that I didn’t really understand clearly, I’m now one of the administrator of the Luminance HDR Project.
Let’s start from the beginning: a few weeks ago I was trying Luminance HDR 2.0.0. It has been released in July so I though it was interesting to give it a go. It was even more interesting because I had to compile the code from scratch using my Mac OS X.
I have to say: it wasn’t as hard as I imagined. Using MacPorts and a bit of patience, I had my working copy of Luminance HDR.
My first question was: why is it a newer software worse than the previous older one!? I know, I lot of people out there had the same thought and I agree with them, Luminance HDR is worse than QTpfsgui for these reasons:

  • The tonemapping process does not produce the same result of QTpfsgui;
  • The UI interface is somewhat not-coherent, because probably it has been touched but too many people with different ideas about how it should be and how it should be changed;
  • Luminance HDR crashes for unknown reasons, expecially using Mantiuk 06.

I am still learning the code and trying to find out where the sources of these problems are, but I’m confident that I will eventually come out with something interesting. So, if anybody wants to collaborate, just let me know.

A new website for Luminance HDR

Luminance HDR has now a new website, based on WordPress. This new website will make easier any kind of feedback between the development team (?) and the users (I hope you are a lot), and we are expecting to receive a lot of feedback in order to focus our work.
The old website is still available here.
