Originally posted by thepedant I am trying to assess whether the various HDR modes are usable as a 'quick and dirty' way of making HDR images. Key question: Am I right in thinking that DCU5 can't replicate the in-camera processing to make an HDR JPEG? One has to use DCU5 to split into 3 raws and then use some other software to combine them? There seem to be some snags doing that on Linux. Luminance HDR 2.5.1 doesn't list K1mk2 as a supported camera and (unsurprisingly) crashes. The command line suite pfstools works fine but then I feel I might as well have done the bracketing myself in the usual way and thus not have an extra step of splitting with DCU5.
I guess DCU is Digital Camera Utility. But I don't get what you are trying to do. Am I correct that you think of decomposing HDR image captured by camera when using HDR program? Is that even possible? I never checked that but imho this HDR is jpeg. Not sure if camera records all frames used to make it as raw images but if it does, you can play with them manually.
As for Linux, you can try blending frames in gimp using layers. It does not support raw images itself so you have to use ufraw plugin or convert to jpeg with rawtherapee.
Anyways, nice to hear there is a Linux user among photographers
