Adobe Lightroom - New features release

Recommended Posts

According to Lightroom Killer Tips (on 16 June), Adobe are releasing updates to Lightroom CC and Lightroom Mobile - but not (not) LR6.

 

The LR Mobile changes allow more editing; while the LR CC adds, amongst other things, a new feature called Dehaze (or add haze) Effect which, Killer Tips, describes as "pretty darn slick..... and for anyone who shoots u/w photography or at an aquarium". Apparently it cuts through haze and doesn't just add contrast.

 

The Mobile version has already appeared through the usual App Store updates. I've not yet received the CC update.

I would say it definitely adds contrast.

 

From trying it briefly I would say that it is another contrast adjustment with a radius somewhere between Lightroom's current Contrast and Clarity sliders. It is useful to have, but I don't see it as that exciting. I am yet to be convinced it does anything that can't already be done with a combination of Contrast and Clarity.

 

It is also in a very annoying position in the menu.

§I just played around with the dehaze feature, and let me put it this way: HOLY F//%( SH/&!!!! That is amazing! Magic! And yes - the position in the menu is... Uh... WHY?!

This is the same image, one with dehaze dialled up to 100 to illustrate the effect:

Here's a crop of a photo I did really quickly this morning. On the left is my standard treatment for haze, dropping the black level (to -50 in this case). On the right is de-haze at 45.

 

There is definitely some combination of contrast, black level and clarity going on there. What I thought was most interesting is that it looks like the color shifted too. This shark is more gray on the right.

I'm assuming you guys have received an automatic update of LRCC?

 

I must have upset someone at Adobe.... it's not reached me yet.

You could try logging out and back in. When Lightroom CC showed up, I had to do that.

I plan to do some testing tonight, but it looks to me like a combination of saturation, contrast and clarity (which is a combination anyway...)

 

It looks great at making the blues really rich.....

Dehaze at +45

 

I need to pixel peep a bit, but initial impression are very favorable...

 

The bad news is that Adobe said in their press conference that they do not plan to release this as a feature upgrade for Lightroom 6. My understanding is that it will not be available until LR7 is launched, if you are not on the Creative Cloud plan.

There's also some sharpening going on with dehaze, as far as I can tell?

I think it is largely a contrast boost rather than pixel edge sharpening.

Thanks for the info everyone. If anyone else hears about this issue, I have been unable to access the full Adobe CC for a number of months & was unable to complete contact to support with my busy schedule, etc. I couldn't get the updates at all this am so I finally called Adobe support the second they opened this morning. I immediately got an engaging, knowledgeable, helpful tech who spent an hour on the phone with me debugging the problem. It was an Adobe bug.

Now it's fixed & I have the new LR CC 2015 & PS CC 2015 all working excellent. Plus Adobe credited me for several months towards my CC subscription. That was very welcomed.

I'm very pleased with the new updates & looking forward to see what they do.

Thanks again for all the info posted here.

Excellent on the refund! That's always a joy when companies do that without a major to-do.

 

I've been using LR for years now - since it was first realised - and think it has just got better and better and there is so much excellent support available from both Adobe and folks who are now making careers out of LR. I've got the Adobe Photography package too (LR and PS) but find I now rarely use PS. Although that might say more about my ability to use PS rather than the increasing power of LR! I do find though LR is pretty intuitive whereas, having done a couple of PS courses, if you don't use it you do forget how to do things with it. It's not straightforward. It's nice to have the option though.

I figured I would peak into the the XMP file to see if I could see some combination of adjustments, but all it says is "DeHaze = +50". :sick:

The Dehaze effect is probably based on this paper or something similar...

 

http://research.microsoft.com/en-us/um/people/jiansun/papers/dehaze_cvpr2009.pdf

 

It's a simple observation at it's core, in your image for every pixel there's usually a dark one closeby (except for the sky), as the depth of the scene increases and things get more hazy that dark pixel tends towards the "haze color". So at every pixel you can iterate over neighbors, find the dark pixel, and estimate the depth/haze by seeing how dark it is. From that information you can remove some haze by solving for RealColor in an equation that looks like this, ImageColor = RealColor* (1-hazeFactor) + HazeColor * hazeFactor, and blending with your image. Well actually the paper applies other techniques to make the results better and evaluate the haze color from the image so it's much more complicated than that.

 

So you're probably not redoing that using contrast and the other standard manipulations available in Lightroom.
