Dehaze in ACR 9.1 (for CS6 users)

It works! Thanks a lot.

However, most of my pictures are JPG. Do you know how to apply dehaze on a jpg file?
The same way you apply it to a raw file. Open the JPEG in ACR and use the preset(s).

From Bridge you can open directly to ACR with a right click. From Photoshop you can use Open As and select Camera Raw to open a JPEG into ACR.
 
To dehaze an image (defog as I call it) simply open unsharp mask or smart sharpen. Enter amount 60, radius 20, threshold 0, simple eh! I use 40% of those values, A 24, R 8. Easy eh! Try it with any version of PS
 
It would be interesting to see how that deals with the smoke in the image here:

 
I only use the mild setting for portraits. I have no idea how it would work on that misty image.
 
Users in Shanghai and New Delhi will be especially thankful to have this dehaze tool at their disposal.
 
In answer to Dr_Jon's question, I've tried on the smoky image using the Unsharp Mask technique as described in above post (Unsharp mask Amount 0, radius 20 threshold 0) :-

I thought as much. The only effect this adjustment has on haze is to accentuate it.

Perhaps in a future release, Adobe could introduce this as a Re-haze tool--to create haze where none exists.

Whoops!!!

Above should read Amount 60, radius 20, threshold 0

Obviously you are referring to the well known HIRALOM method, but you have got the numbers wrong I'm afraid. The method calls for High Radius and Low Amount, ie Amount <= 20 and Radius 60-80... Check it out...
 
Note this example wasn't using the Adobe tool but looking at another way of dehazing (although suffering from a typo). See here for using the adobe tool: http://www.dpreview.com/forums/post/56018486
(The interesting bit being the smoke was left behind.)

Also Adobe already supports adding haze/fog, just use a negative number (see my original post at the top of the thread).
 
Someone asked about Dehazing with LR5 in the LR 6.1 version of this post, so I mentioned the above trick. As the results didn't seem great I had a play and found the best I could get was with 73%, 72.4 pixels (that's just where the slider ended up, not carefully chosen)and 0 threshold followed by 150/1.2/3, which did help a bit, though would also need a denoise. I'm not sure it was worth the effort...

USM dehaze attempt, as described above.

Hello

Thanks for your work and sharing it.

It works great

How can it be applied selectively?

Thankyou

Ray

I'd assume have a normally processed image on one layer and a dehazed one on another and use an eraser brush with modest opacity/flow to suit.

Within ACR, there's an "adjustment brush" where you can make this selective edit on the raw file. No manual layers required, with the ability to erase/change opacity as needed. Couldn't be easier.

Photoshop CC has Dehaze, so presumably you can run it within a selection.
 
Any clues as to how this might be achieved in Lightroom 5.7 ? I just don't want to start renting software...

Perhaps one of the sliders could be hijacked for dehaze? Or perhaps it could be rigged as an external preset?

Looking for ideas.

I'm sorry you can't do it in Lightroom 5.x, you either need a subscription to CC or to have bought or upgraded to Lightroom 6 (where, like ACR, it's a bit of a hack). For LR6 see my post here (for CC it just works):

If you want to receive new features you'll have to "rent". If you don't want to rent, don't complain about missing out on new features. In this case your "complaint" is in trying to get a new feature you aren't willing to pay for.

You mean hack Adobe's software to avoid paying for a feature.
Looking for ideas.
Either purchase a subscription or purchase a copy of Adobe CS6.

Good luck.

This isn't strictly true, as the feature is in Lightroom 6, which is sold, not rented. I'd be tempted to get a subscription rather than pay for an upgrade from 5 (if they still offer it) though.

BTW I didn't intend to use the term "hack" in quite the way people tend to these days, i.e. as in something illegal. You don't have to modify any software, you just can't access it as simply (it's present in LR6 and does work with presets, you just don't get the handy slider, so you either need a preset from someone editing on CC or just make your own preset).

They could upgrade to LR6, although the subscription is a very good deal if you don't have much of a recent investment in Adobe's photography software you want to get some value from. (Less so if, for example, you recently bought PS CS6, as you get no credit for that.)
Good luck.
