Adding Depth with Negative Dehaze

The Quest for Depth

 






Dehaze


1st Draft
The Cover WILL Change

Now that I have submitted my 2016 Calendar, I have to come up with another excuse for lame blogs. This week it is that I have spent the last several days visiting my daughter in Boston and then joined our friends for the annual Rye Beach days. I'll share some coastal pictures later, but this week I want to provide a quick look at a new tool introduced in the recently released versions of Lightroom and Photoshop CC 2015. 


 

We landscape photographers have a love/hate relationship with fog and haze. Crystal clear air is beautiful, but a little haze can work wonders to provide a sense of depth and mystery.

I'm always looking for ways to provide the impression of depth on my images. It is an inescapable reality that, without the use of funny looking glasses, photography is a two dimensional medium.  Compositional elements such as converging diagonal lines and the inclusion of foreground detail can provide a three dimensional feel, but a little mist or haze in the air can create a layered appearance that goes further to reveal the depth. But what can you do when nature stubbornly provides only "beautiful" crystal clear air.

Spotlighting

I have discussed a few of the tools within Photoshop which can enhance the appearance of depth. Spotlighting techniques, use masking to localize an area of contrasting brightness to a distant point, to draw the eye away from the foreground. I recently discussed the use of Negative Clarity to selectively soften distant portions of an image. With the introduction of the Dehaze Tool we have another option for adding a layered appearance to our images.

Depth from Negative Clarity

Dehazing
 The Dehaze tool was introduced in the 2015 versions of Lightroom and in Photoshop's Camera Raw. It is primarily designed to reduce the softening effect of hazy air, salvaging detail in images that would otherwise be washed away. The Dehaze tool is easy to find in the Effects Panels of both Adobe Camera Raw and Lightroom's Develop Module.  Within Photoshop, Dehaze can be accessed as an option in the Camera Raw Filter. The tool works well, but can't remove the haze entirely and if taken to extreme can create a dark, overly contrasty, effect that requires further adjustment. I suspect that this is one of those tools that will get better in future versions of the software.

"Negative" Dehaze
Much like with the Clarity Tool, I have been more interested in the Dehaze Tool's ability to go in the negative direction and add haze. The global softening created by "negative Dehaze", has limited usefulness, but when the effect is applied locally, to more distant parts of the scene, it can produce a layered look that reveals depth.

Global Haze

O.K., Let's drop the double negative and just call it the "Haze Effect". As with the local application of negative Clarity, haze can be applied to the entire image and then restricted to a specific area with the application of a layer mask. Although haze can be created from within Lightroom, I find that the localized effect is easier to control as a Camera Raw filter in Photoshop.  

Distant Haze

 
I create a Camera Raw Filter Layer and then start by adjusting the Dehaze Tool to apply a level of haze which is more intense than I expect to use as my final result. I add the layer mask to localize the effect and then adjust the layer's opacity to reduce the initial high intensity of haze. I find that the haze effect works best when it is not overdone and is applied with a soft edged mask, but the extent and intensity of the effect can always be readjusted with the masking and the layer opacity. All of this can also be done with a Smart Filter layer.

The local application of negative Clarity and Dehaze either separately or in combination can add significantly to the sense of depth in an image. I have been enjoying playing with these adjustments, but as is always true with new tools in Photoshop, it remains to be seen how they will fit into the full range of techniques that are available. 

Localized Dehaze

 Regardless of its eventual place, Dehaze is one more reason to keep up to date with the latest versions of Photoshop and Lightroom.  So have fun.  There are new toys in the sand box.

Negative Clarity for Landscape Photography

Let's talk about "Negative Clarity". This phrase sounds like it belongs in politics and not photography, but Clarity, both positive and negative, is actually a relatively new Photoshop tool that is remarkably powerful in affecting the contrast and mood and of your images

Mitch bathed in WAY too Much Negative Clarity

The clarity tool first appeared in Lightroom with version 1.1 and worked in a scale from 0-100, that is, only in the positive direction. In Version 3.3 the tool acquired negative values, ranging from -100 to + 100, and it is the effects of negative Clarity that I will focus on for this article. Clarity is also available in Adobe Camera RAW and, significantly, with Photoshop CC, it is found as part of the Camera Raw Filter menu.



Finding Clarity
The Clarity slider is found at the top of the list of the last three tools in the Basic Panel, above Vibrance and Saturation. Simply stated, Clarity has its effect on the mid-tone contrast of images. It adds

A little Positive Clarity

contrast without bringing out excess grain in the highlights and shadows, as might a general increase in contrast. It give a sense of sharpening without actually adding sharpness. Early versions of the Clarity adjustment tended to be bothered by Halos around areas of high contrast, but in the more recent editions of Lightroom and Photoshop this problem is much less noticeable. Increased Clarity works best when an image has a lot of detail in the mid-tones. I often use it to bring out the detail in my landscape images, but recently I have been impressed with how selective use of "negative" clarity can add a sense of depth to many of my images.

It should be no surprise that moving the Clarity slider into the negative range causes a decrease in mid-tone contrasts resulting in a softening effect. Applied generally, negative Clarity causes an increasingly prominent soft, watercolor-like appearance, but I have generally used it selectively to soften skin tones and blemishes. Taken too far it can create a plastic appearance, but used in moderation it can apply a beautiful soft air-brushing. Not that my beautiful daughter needs any air-brushing!

Selective Clarity
Selective application of either positive or negative Clarity can be applied in Lightroom or Adobe Camera RAW using the Adjustment Brush, but now that Clarity is available in Photoshop CC as part of the Camera Raw Filter it can be more easily controlled and finely adjusted. By using Clarity within a Smart Filter I can make adjustments in the intensity of the effect and control its application with a mask.


Early Spring Mist

A few weeks ago I was out shooting in the soft mist that so frequently develops as snow meets the warm air of our early spring. I love this barn nestled in a valley in Chesterfield, New Hampshire and on this day the distant tree-line was diffused by the hovering mist. Back home I felt that the image didn't accurately reflect the depth of the scene as I remembered. I wanted to

Fully Applied Negative Clarity

accentuate the contrast between the sharp detail in the foreground barn and the softness of the distant trees. I started by creating a smart filter and then experimented with the application of a moderate amount of negative Clarity. The whole image took on a softening reduction in mid-tone contrast, but then I applied a gradient mask to block the

Selective Negative Clarity in a Smart Filter

effect around the barn and fine tuned the mask by painting out the effect in the extreme foreground. The great thing about using the Smart Filter was that I was able to further adjust the amount and location of the negative Clarity effect. In this case, as I often do with other layer adjustments, I dialed up the negative Clarity a bit higher than I felt was optimal and then pulled back on the effect by adjusting the layers opacity. In this image, I liked the way the Gradient mask allowed a more gradual application of the negative Clarity, but in other situations a harder mask works well.


Buckets

Sugaring season is upon us and I was recently shooting the buckets clinging to some truly majestic Sugar Maples in Dummerston Vermont. I wanted the tree to stand out against the pasture and the distant, mist shrouded, trees. I found that a touch of negative Clarity worked well. It was relatively easy to create a mask to

shield the foreground tree and nearby snow piles from the softening effect and, here again, I was able to dial the negative Clarity slide up and down until I had what was just the touch of softness that I wanted. After reducing the size of the image for web use, I found that I needed to increase the negative clarity effect and the nice thing about using the Smart Filter was that it was no problem to make the adjustment. 





Is Photoshop great, or what!

Leaves with a Touch of Negative Clarity

There are other approaches to adding depth to images. Backgrounds can be softened with the addition of a selective
Gaussian Blur, or contrast reduced by decreasing the highlight and black setting in a levels layer. Each has its own unique effect, but I have enjoyed my recent discovery of the soft feel that results from subtle selective adjustments in negative Clarity. Like any photoshop adjustment, it is possible to overdo negative Clarity. It is all a matter of taste. Applied to excess it can lead to a an unnatural sense of viewing the scene through grounded glass, but subtle adjustments can add warmth and depth to an image. Give it a try, if for no other reason than it is a fun term to use especially when you can bathe a picture of your local senator or representative with well deserved veil of softly obfuscating "negative Clarity".
