Channels and Mask/Selection tools

Using both the magnetic lasso and the lasso tool

I was able to select the wall area ( an area that I

wanted to change the curves without affecting

the rest of the image). Once the area was selected

I was about to reduce the amount of green and blue

in the selected area.

Once again using the lasso tools I selected the

foreground area and on a layer mask add a

a desired gradient.

Even though this image is not a strong image to

use such tools, many times in my work I have

wanted to change the curves or levels in selected

areas.
