okay, this is for my june free study probaly, so I can't post a picture. Let's say I have a slightly blown out sky on a landscape, with a very leafy tree in the foreground (properly exposed) I want to make everything behind the tree darker, even things that have roughly the same light value. Usually when I want to do this, I just duplicate the layer, use the lasso, and cut out the foreground object and make adjustments. But this tree has thousands of leaves to cut around. is there a way to "cut it out" I'm not familiar with adjustment layers, would those work, if so... how. I tried the lasso, and it didn't quite get me where I wanted to go. any suggestions?

| Take the time and mask it or use a plugin like Knockout or Mask Pro |

Did you try using the magic wand? Just click on the sky, then hold down on the shift key and keep clicking in the sky until you get all of it that you want. Turn anti-aliasing on to make sure the edge isn't too sharp.
Also, you can use Select Color Range under the select menu and then click on the sky. Again, click on the preview or even the image itself multiple times with the shift key held down until the entire sky is selected. This will select other pixels in the image that are not in the sky, so you'll need to use the lasso with the Alt or Option key held down to deselect the pixels in the image that you don't want to change.
Good luck!

| If you have Photoshop CS, try the 'highlight' part of the Shadow/Highlight adjustment tool. That might handle it. You might also try a Curves adjustment on the Blue channel. There are many ways to approach the problem, and they don't all require masking. Good luck. |

| Try burning, with the opacity set fairly low (around 30%). This will allow you to "build up" the area. |

For trees, the Extract command works with some success. After extracting with the smallest brush you can feasibly use, remember to duplicate the layer a few times to get rid of leftover garbage.

There is an incredibly powerful, trivially simple and very quick way to do this.
The trick is to let the image itself drive the selection.
//www.pbase.com/gordonmcgregor/imagemasks demonstrates the basics of the idea. Once you get the hang of this, there is no real need for lassos, extract tools or third party solutions for most typical photographic selections. It is amazingly powerful, yet most people still seem to use lassos and magic wands which are great for graphics type selections but pretty poor for photographic images. |

Gordon is right on the money here - using channels to drive the selection is perfect for irregular selections like this.
Another good example for using this technique is when you want to select a person and extract them from an image, and there is flyaway hair that makes for very tedious selection work.
This is another tutorial that I had bookmarked that shows the technique used in that situation, which would be very similar to selecting a sky behind trees and leaves:

Those are great tutorials - thanks to both of you for sharing the links. I only wish I had seen them a week ago!

thanks peeps. I think that helped out tremendously. Using channels for a selection is a great way to do it. It took a little bit of practice, but I think I have the pic the way I want it now. I love this site, and all of it's helpful members.
