X3F Tools and Kalpanika - release 0.53!
22

Hi all,

This post contains two announcements, the end of Kalpanika and the release of the "Kalpanika" converter 0.53 as open source, now called X3F Tools again.

We had a fun time in Kalpanika and Kalpanika made the making of the color conversion code possible. We were four active people that together was the melting pot for ideas. And those are the guys

  • Scott Roberts - the one that took the initiative to forming Kalpanika, the one that did speak with Sigma and was the general driving force.
  • Erik Karlsson- the main programmer of the color conversion and the noise reduction code, the one that made most of the work, and also happens to be my son
  • Mark Roden - an image and noise reduction expert. Great help there! And also writer of some of the experimental code.
  • Roland Karlsson- myself, and the orignal maker of X3F Tools. It might be so that I also have written some of the new code

The reason we terminated Kalpanika was that we saw no way to get rich from it. Selling a converter to you guys? Hmmmmm ... no ... not millions of escudos I would think. And Sigma mainly wanted us to improve high ISO - something we did not. Thanks Rudy Guttosch (Sigma USA) for very constructive conversations.

So, what have been released? Here it is

https://github.com/rolkar/x3f/releases/tag/0.53

There is a release note there and source code and binaries for windows, osx and linux.

You can use the code for all Sigma cameras. The Polaroid X530 we do not support. We think the color conversion is fine, except for one thing. There is still a green hue sometimes. Until that is solved we cannot call it a product and give it a 1.0 version.

Please feel free to download and do whatever you want with it.

We plan to hack more. One thing we really want to do is the actual integration with Lightroom and ACR. The DNG output of our converter is actually quite cool. We let Lightroom and ACR do the conversion for us. We only construct the color conversion matrices and do some noise reduction.

This means that we avoid the clipping problem that you get if you make a TIFF, e.g. from SPP. Nothing is lost. The data is still RAW (minus noise).
