Lightroom Clarity / Local Contrast Adjustment

PostWed Dec 18, 2013 11:48 am

I'm trying to re-create the look that using the Clarity slider in Photoshop Lightroom gives, if anyone here has used it then you'll know just how awesome it is.

From what I have gathered it appears to apply contrast in the midtones around whatever contrasting edges you have in your scene. From doing some Googling, this appears to be known in the photography world as Local Contrast adjustment. http://www.cambridgeincolour.com/tutori ... cement.htm

One way to recreate it is to create a blurred matte of any contrasting edges in your scene and apply a curve through this matte. This matte can be created by blurring the scene and then subtracting this from the original image. (See attachment). This gives me a luminance matte but can anyone think of using this to apply my curve through? Or is there another to recreate this effect that I'm missing?

Ideally, Blackmagic will just give us a Clarity slider in the next update :)

Hey Chris,

I'm a HUGE lightroom user. Any chance you can provide a more step by step explanation of how you set up this process and these nodes? I would absolutely love to recreate this lightroom clarity!

Unfortunately I never quite figured out how to get this working properly. I'm going to have another stab at it when I get some free time.

Again, I'd like to suggest that BM bring something like the clarity feature to Resolve. The way it adds contrast and brings extra depth to the scene is unlike any other grading tool I have seen before.

I saw a similar tool mapped in the BM resolve panel (the big one).. I did not see it in the GUI unfortunately...

Let me think about it...

node 3 is nil
node 1 does the blur
layer mixer setup for subtraction

node 4 is the b1tch: the idea is to get the rgb info and generate an alpha that match. Is a luminance key at the moment but if you have a better idea...

Node 5 does the curve adjustment (and the strength of the key) Y only so you do not introduce color shifts...

How that work for you? (yes, that's me...)

It's already in Resolve 11, it's called "Midtone Detail". You can access it under the raw panel and also under the color match panel.

Yes I notice that, but it was a good exercise nonetheless.

Thanks! That's exactly what I was looking for. I'd never even looked at them controls.

Also thanks for your efforts, Walt. As good a solution as yours was, a quick slide of the midtone control is much simpler than creating that node tree every time ;)
