Hello Magic Lantern gurus,
I have just installed Magic Lantern as I am curious about the DUAL ISO module.
I have a question. The answer may be obvious for people familiar with the differences between DNG and CR2 formats, but I am wondering:
Is there a fundamental reason why the output of cr2hdr is a DNG file and not a CR2 file? Or could it be done (provided there is time and interest in it)?
Please enlighten me!
Thanks.
CR2 -> Proprietary format. Specs not open to public.
DNG -> Open format.
Why on earth should a project dedicating itself to open source philosophy even consider using CR2? Do you *need* CR2 for your workflow or any other reason?
Up to now I only use Canon DPP for my workflow. It deals well with Lens Aberrations and gives me enough sliders to gently adjust the image.
I do not say I absolutely need cr2. I am happy to deal with Dual ISO images in another software specifically.
Am I wrong or isn't some part of the cr2 format understood enough to be able to write a cr2 file out of cr2hdr? Or does this just make no sense (independently from the fact that cr2 is proprietary format or not)?
Somebody actually looked into it (http://www.magiclantern.fm/forum/index.php?topic=10895.0) and managed to write a CR2.
Don't remember the source code being published anywhere.
Thanks for the information.
I am trying to figure out how to apply Chromatic aberration corrections outside DPP since we use DNG on the hdr image. Ideally I am looking for a solution similar to Digital Lens Optimizer from DPP. Unfortunately, I am not sure that it really possible since I believe there is no focus information in DNG, Correct?
Automatic correction of lateral/transverse CAs is very basic to most RAW converters/image processing tools. Take your choice.
OK. I am trying Rawtherapee.
