Perhaps a naive thought about the histogram (copy histogram)

Software darktable

I just thought about this and if this is possible and if it benefit in any way.

Lets say I shoot RAW and JPG. The JPG is a created by the in camera ‘magic’ with its own specific conversion.

Now in darktable the RAW looks differnt of course cause …well, it’s a conversion of the RAW and need to be processed.

My idea to get the RAW to look more like the JPG would be a kind of copying the data from the JPGs histogram and paste it to the RAW.

Like I said, perhaps a very naive thought so sorry if this is stupid :slight_smile:

Thanks

darktable already has a mechanism for doing this, darktable-chart: https://www.darktable.org/usermanual/en/darktable_chart.html

That’s not a stupid thought. RT does that with histogram matching…

Thanks, I need to look into that darktable-chart but I thought the process could be much simpler (without bying a colorchecker etc)

Like @heckflosse, said, RawTherapee does exactly what you’ve described. It’s called “auto-matched tone curve”, and it makes the processed raw look like the embedded JPEG. Now, how that goes depends on how good is the JPEG… :smiley:

if you don’t need exact colors but just a similar processing you can use this way to avoid buying a target:
