0.2.3 stable release After 4 months of lack of feedback from 0.2.2 beta version here's what I call the 0.2.3 release.Judging from the lack of interest to this library, it either works perfectly, or it's absolutely useless :) I'm not going to invest much more time into it, since it already does what I needed from it and unless someone comes with a great enhancement idea, I don't see what more can be improved here.
A small demo how UFRaw interacts with lensfunI have spent some minutes to record a demo of the new UFRaw lens correction page, which uses lensfun to do the actual work.The demo is a 1.7Mb file encoded with H.264 embedded into a Matroska container. VLC and mplayer will play it without problems, gecko-mediaplayer will not, because it does not know the .mkv extension (shame!). So please download it and open with any decent video player. http://lensfun.berlios.de/files/ufraw-lensfun-demo.mkv
Public beta release 0.2.2bToday I released version 0.2.2 beta of lensfun. This is the first release which does not require doing a SVN checkout: you can download the tarball from the download section of the berliOS project page.
If you have a SVN copy already, you should just do svn update as usual; I did not tagged the 0.2.2b version, I'm going to tag only the 0.2.2 release.
lensfun goes to massesHalf of year passed since the first public release. Let's summarize what happened during this time regarding lensfun.
Lens calibrationWhile implementing lensfun support into UFRaw I'll try to expose my thoughts on the future of the project here.
Beta testing openNow it's time to present the project to a wider public. I hope there is people which will find the project interesting, but in any case the first target I have in mind is UFRaw. I will work on adding lensfun support to UFRaw in the near future, and I hope that working on it will help me understand better the weak points of lensfun.
Initial import into SVNFinally, I considered lensfun mature enough for the first upload to BerliOS SVN. This is not a release yet, just that I think that the code can be useful at this stage to anyone of interest. Also I have set up cron on BerliOS to update the library manual every night from SVN, so it always should be up-to-date (or broken, hehe). At this stage the API is generally speaking ready for the first release. I can't think of anything I would like to add or modify at this stage. The implementation is also more or less finished, I have to do some testing before releasing.
Welcome!This site is all about the lensfun library. What is it, you may ask? Digital photographs are not ideal. Of course, the better is your camera, the better the results will be, but in any case if you look carefully at shots taken even by the most expensive cameras equipped with the most expensive lenses you will see various artifacts. It is very hard to make ideal cameras, because there are a lot of factors that affect the final image quality, and at some point camera and lens designers have to trade one factor for another to achieve the optimal image quality, within the given design restrictions and budget. But we all want ideal shots, don't we? :) So that's what's lensfun is all about - rectifying the defects introduced by your photographic equipment. |
