dehaze
Does anyone have any insight on the new dehaze filter? I've followed the tutorials but the results seem somewhat random to me and I don't know how much noise or distortion I am adding. Thanks.

From what I have seen in videos online, the key things are
- don't overdo it.
- use the picker to select a suitable shadow tone. I'm not sure that there is a scientific way of doing that other than trying clicking in several different places until you get a result that you like the look of.
- expect to use it in conjunction with other tools (levels, clarity, etc) not as a complete substitute for them.
As to how much noise you are adding - it's quite possible that you are introducing some. I took some photos of water birds in the fog last week. In Manu of the raw images you can hardly see the bird at all! Using levels (a lot!) improved matters quite a bit, but at the expense of a lot of noise in the darker areas. I got one shot that I was reasonably pleased with by using the Dehaze tool to a modest degree (see point (1) above), plus some use of clarity and levels, etc. There is probably nothing that the Dehaze tool will do for you that you couldn't do yourself with a combination of other tools. But it may speed things up and give you a starting point to build on with the other tools.
And you'll know whether or not you are getting too much noise if you see it to an objectionable amount. In the end it is a question of trusting your own eyes, I think. You might get just as much noise by trying to deal with the haze by hand using a combination of tools.

Very helpful Ian! Thank you.

Ian is quite right and his advice is well worth following. You should have seen the weird results you could get in the beta of CO21 when you could apply much higher levels of de-haze ;-(

I also use Affinity. Does anyone know if their dehaze is any better?

I would say not. It is rather different. It has more sliders, but it is very much geared to the assumption that haze is in the distance (which of course it often is). I haven't been using Capture One's dehaze tool much yet. But I did find that it gave me a useful starting point on a shot I took the other day of a water bird on an extremely foggy day. I have just tried the same shot in Affinity and (1) you can't get to the Haze Removal tool until you have come out of the Develop Persona, and (2) I couldn't get it to do as much for me as the Capture One tool did. (Also I see that Photoshop has a dehaze slider in Camera Raw, so at an earlier stage in the process than Affinity does. And a brief experiment with the same image shows that PS, although it only had one slider for dehaze, was more effective than Affinity. Capture One's slider seems to do much the same as Photoshop's one, with the added advantage that Capture One also gives you the shadow tone picker.)
And I am sure that with both Affinity and Photoshop, you'd have to use their dehaze tools in conjunction with other tools to get the best results, just as you should in Capture One.Ian

Thank you again Ian. I love C-1 but find some features better in Affinity, from my perspective. Unsharp mask, for one, gives me a better result than C-1 clarity or sharpening.

Does anyone have any insight on the new dehaze filter?
Yeah - ask about it in the Capture One 21 forum, as it's not part of version 20.
