Selecting sky inside tree branches

[richrd]

I once found a way to select all the small spaces inside branches but naturally I forgot how.

I know I bumped the contrast between the sky and branches, lightened the sky and changed the sky color on another layer. 


Then if I remember right, I just turned the layer opacity down and inserted the new sky.


But how did I change the sky color


Thanks

Hi richrd,

Is this by any chance the tutorial you are talking about?

PSE15 Manual Luminosity Mask Blending

Richard, what you say makes sense. You could make a duplicate layer of your photo. Tweak the levels on just that layer so that the trees look black and the sky looks white (or at least have a high contrast between them). Then use that layer a luminosity mask of your sky replacement. Experimenting with the blend mode (eg Darken) may help with some kinds of Sky replacements.

Here is another tutorial

Kind regards

Try using a threshold adjustment layer to create a very detailed mask. Once you create, Invert it and use it as a mask on your image. Put your new sky layer underneath and it will show thru.

Frank, thanks for bringing this up! It's my go-to technique for sky replacement when tree branches, foliage, etc. are involved. I find it very effective.
