From CR2 or DNG to MLV?
« on: January 29, 2019, 11:16:38 AM »
I am wondering wether it is possible to convert CR2 odr DNG pictures back to MLV? I would like to try darkframe subtraction on regular pictures, but so far the only way to do this seems to be using Rawtherapee, however, i would rather use Adobe Lightroom. Also, i would need to average dakrframes taken in photo mode, which cannot be done by MLV dump. My idea would be to take my CR2 files, convert them to DNG with the Adobe converter, make an MLV file out of DNGs photographed with the same settings (shutter speed, ISO, same event) and subtract a matching averaged darkframe from this MLV, then export back to DNGs, which would be edited as usual in Lightroom.

In short - use the same workflow possible now with MLVs also for stills. Capturing to MLV via fullres silent pics is not feasible for most of my work, since i cannot use a flash in this mode.

Would it be possible to have a "reverse mlv_dump", which takes DNGs und makes an MLV out of them?

You can do Darkframe averaging with CR2 in Rawtherapee

Also flat field subtraction
once you go raw you never go back
