I am trying to find out the best way to remove the sky from the background here (Including all of the little spaces between tree branches)
The Cutout Lab doesn't seem to work for how intricate the selections are. All help is appreciated!
I use the magic wand mask
Try the "magic wand mask" tool. Play with the tolerance adjustments. Should work well.
Should be EZ to insert background you prefer on this PNG:
Thank you Jeff. The issue I'm having is "Selecting" all of the small spaces between the leaves and branches. What tool is best to do this? If I use the magic wand, I have to select each little area. This photo is just one example but others I have are more complex. - Any help is appreciated.
Yes, this is more of an advanced technique as you've discovered. There are a few strategies. Maybe I should make a video tutorial on it. I found a novel technique many years back, I need to find it again. I think it showed channel masking or luminance masking.
For your example though, I used the Magic Wand tool and "Select Similar" mask function., and played with feathering on the leaves area only. Then I tried something new - using a merge mode to take away the final bits of white fringing around the leaves.
