Another "dehaze" example.

I really like the dehaze function in ACR (I don't use LR). While not perfect, it does simplify the removal of haze in many shots. I took this one in Hawaii last week on a hazy day. The only adjustment was the dehaze tool, at 100%.

Default settings, straight from the camera via ACR.

Same image, dehaze set to 100%

I'd probably add a little more contrast and saturation to the image, but dehazing can work well.

DeHaze works well and you can get a similar function at Photoline 19 if you don't want to pay Adobe the high costs

FWIW....I did a comparison with Corel and Athensoft. I think the deHaze is just another gimmick, This image just lacked contrast and vibrance.

There is a difference; note the absence of blue skies in your conversion.

There is NO blue sky in the original photo! Therefore it would be inaccurate to add it back. I removed cyan in the clouds to make them gray. But if you are happy with your results via the dehaze, great! But I would suggest otherwise.

No, it isn't obvious, but there was blue sky in real life. The dehaze filter didn't add it, it just removed the haze.

Re: Another "dehaze" example.

For me, where dehaze really shines is when you use it as a filter from Photoshop and mask out the parts of the photo that don't benefit from the dehazing. If you can stand duplicating the image, you can apply different dehazing to different areas of an image. Unfortunately, Adobe still doesn't allow you to apply a mask to an individual filter, so maximum control over dehaze as well as other ACR capabilities are limited by how large you want your Photoshop file to get.

People's reactions to Dehaze reminds me of when Shake Reduction was introduced. Some people saw it as gimmicky and never learned when or how to use it. Those willing to spend the time would sometimes find it was the best tool for a problem photograph -- even for issues that had nothing to do with camera shake. Neither tool works well on every photograph -- but knowing when it does help just puts another possible tool in your arsenal.

Here's my try (and practice on new dehaze filter) using Dehaze 60 and following up with CS6

Dehaze 60 + Normal CS6

Nicely done. Any of the mods in this thread are light years ahead of the OOC shot. Nice to be able to save an otherwise worthless shot.

Re: Another "dehaze" example.

I used the dehaze plug in provided by one of our Forum members as I do not have the CC version of LR. I then applied the plug in version slider to several photos from my January trip to Iguazu Falls (Argentina). The original photos had a great deal of haze due to various environmental conditions. The plug in slider did a decent job in making the photos more presentable.

Here is the link to the plug in in case you did not see it earlier.

Take care, Larry

But note also the absence of green trees in the middleground of the dehaze conversion. Dehaze created a pronounced blue cast in the green foliage.

I think the lesson here is that you can't fix a hazy image like this with global adjustments. You have to deal with the sky separately from the rest of the image.

Used Apply Image, no dehazing.  gc

Yes, it needed more work after the filter, but I posted to show what the dehazing filter can do on its own. The shot is savable through some good PP, with or without the dehaze filter.

Not that hard to de-haze this image.

Auto-level, contrast mask biased towards the light areas, added some glow to the waterfall (personal choice and taste), boosted the yellows.

Nice. I'm stealing some good advice and techniques from this thread! Love it.

V1 of dehaze from Thomas Knoll in 2003

AKA large radius USM. I read about it back in 2003 when it was described on Luminous Landscape:

I learned of it from Thomas Knoll, a member of a couple of my workshops during 2003, and not-incidently, the original author of Adobe Photoshop and Camera RAW. Thomas says that he certainly didn’t develop the technique, but I haven’t yet seen or read about it anywhere else, though it appears to have been around for a while.

(The article must have been updated in some way in 2009. I remember reading essentially the same article on LuLa in 2003 (or 2004.))

I've been using large radius USM ever since to dehaze images. Here is the original image with USM at 100%, radius of 100

This isn't as punchy as the one done with the new Dehaze tool, but it is a good starting point.

I'm a low tech Photoshop user: I use Smart Sharpen for regular sharpening and have USM set with a large radius for "dehazing."

Re: Another "dehaze" example.

people just live to complain because they are not satisfied with their own lives and search for any excuse to play victim in hope of finding sympathy. It's very unfortunate, I actually used to be like this too. Any new tool is a good thing because no one is being forced to use it. I have used it the masking way (ACR filter on 16bit image) and it works very nicely.

There is a difference in that a large radius USM increases local contrast in all parts of the image, whereas a dehaze filter only increases local contrast in the low-contrast parts of the image. That's at least how the dehaze filter in DxO's OpticsPro 10 works.

I figured that it would be more subtle. Like how the shadow and highlights sliders are more than a reverse S curve.

I'm sort of amazed that it took from 2003 to 2015 to add "only increases local contrast in the low-contrast parts of the image" to large radius USM.
