@Jamesstaddon and I were noticing something about some pictures I shared with him.
The histograms just don’t line up, when exported from Darktable and imported into Lightroom.
The attachments should tell the story fairly well.
I wonder why this is, and if anyone can clarify it for me?Attachments:
Are these files JPG files, or RAW? If you take the exact same RAW file and view them both in LR and DT at the same time do the histograms line up?
I’ll also have to bear in mind that both DT and LR do some automatic per-camera touchups upon import, too.
Right, that was the next thing on the tip of my tongue. 🙂
I’d be more inclined to trust DT’s histogram, because LR does a lot of things behind the scenes. Have you checked RawTherapee’s histogram to see how it compares?
I’ve heard of and observed a somewhat related problem with my Pentax cameras. The histogram on my camera is based off of the highly compressed JPG preview embedded in the actual RAW file. That means that “clipped highlights” that I see in the on-camera histogram aren’t actually clipped in the RAW file. Kind of annoying. 🙂

No; good point. I’ll have to try that and post screenshots when I can.
How (if it’s possible) would you undo the automatic adjustments that LR does, since they (unlike in darktable) don’t appear in editing history?
And, having not used RT much at all, does it do the same as DT and LR in this regard?How (if it’s possible) would you undo the automatic adjustments that LR does, since they (unlike in darktable) don’t appear in editing history?
It’s impossible in LR to my knowledge. Yes, RT does also apply some auto adjustments, but they can be turned off by selecting the “Neutral” (or “Flat”) profile if my memory serves me correctly.
