Support for Linear DNG files

Posting rules: It shouldn't need saying, but... play nice. Please keep your discussions civil. You can disagree, just don't be disagreeable. And, of course, all of the usual stuff like no spamming. Tex adds: I'll be rigorously enforcing this as we go along. We're probably going to be a small community in a little lifeboat, so we can't have members at each others' throats. This is for the sake of the project as a whole. So when you post, pretend you're speaking in person with your very wealthy auntie who has always treated you wonderfully and currently lists you prominently in her will. I won't be tossing anyone out of the forums because we are all in this together (except spammers: immediate membership cancelation), but I'll delete suspect posts right away.

Support for Linear DNG files

Hi crew,

I'm an oddball---I shoot Sigma cameras. Having confessed that, I've used Lightzone since the early days as my editor post-raw-conversion in Sigma Photo Pro (SPP). The current sd Q files, coupled with SPP on my semi-aging iMac have left me wanting a new workflow (due to the time it takes to process a file). A group of dedicated Sigma afficiandios have built a convertor that takes x3f files and makes a linear dng file.

Right now, these linear dng files do not work with Lightzone. I'd be happy to supply files, if a developer has some time to take a look. I'm also pretty sure that this is a borderline use case (it'll impact all three of us... :)). However, I'd very much appreciate someone taking a glance to see if it's possible.


Me too! It would be nice to

Me too! It would be nice to have support for Kalpanika's linear DNGs. The DNG files from the new Sigma Quattro H will be linear straight out of the camera, so it would be needed for future support anyway.
