Blown out sraw / linear raw files wanted

Do you want me to open a ticket?

No. Already have it fixed here, just have to do the opposed means yet.

Thanks @jorismak - i knew those images as raf files so very good to see how it works out with these dngs! Those two work in a perfect way, could you share some more?

Anything you are looking for ? Large clipped areas ? All channels clipped , only a few ?

A selection of very strongly clipped, blown out areas surrounded by dark parts. Artificial lighting…

This is what comes to mind. The clipped areas are probably not surrounded by dark parts.

This one is a large patch of clipped against hard edges of darker / ‘real content’. But not all channels are clipped, though.

Not at all what you asked for, but I always think this is a nice test case because there is a lot of different channel clipping happening, and every algorithm seems to produce something different.

Thanks, I will check.

I’ve noticed it’s in master, so I made a new build to have a go.

First thing I noticed - which might very well be my own fault so none of your concern :wink: - is that I opened a DNG file, and I’ve seen a pop-up saying ‘highlight method not availble, falling back to inpaint oppsed’ or something like that.

Probably because I have a preset auto-enabled for setting segmentation with combine to 2 and candidating to 0% as a starting point.

So, nice that it tells me that’s not available and instead switches to oppsed. The thing is, like the right 2/3rds of the image was black. Once I disabled HLR and re-enabled it, it worked fine!

The normal Darktable clipping indicator seems to still do nothing.

But the threshold viewer in HLR seems to work fine.

If I then manually select my ‘segmentation based default’ preset again, it sort of activates it and also sort of falls back to opposed again :slight_smile: .

I do see the popup for ‘falling back to opposed’. My guess is if you fall back to opposed, there needs to be a ‘on change’ event triggered on the dropdown or something, for the interface to be notified of the change :slight_smile: .

Well, the menu was wrong for linear dng or sraws. There never was anything else functional than clip :slight_smile: now we have opposed in addition.

Arrgh, I see what you mean, will take care of it…

As you probably have noticed the segmentation algorithm is not yet implemented for sraw files.

I don’t know yet if the results are as good, would need more examples with smooth transitions from unclipped to clipped, all color channels should be involved.
