Now, it's time to use the Create Path tool!

This selection tool is going to allow us to make a path of points along a portion of an image so we can remove that portion from the entire picture. Suppose we have our image of the daffodils and wish to remove one of the flowers from the picture.
We can use the Create Path tool to trace out a selection area along the edges of the flower we want to remove. First, we zoom in on the region of the image we want to remove. We can do this by looking at the bottom-left corner of our image and clicking on 400% as our level of detail.

Next, we use the Create Path tool to carefully construct a polygonal path around the flower. It'll look something like this when we've finished:
IMPORTANT: Unlike other selection tools, which like us to complete an entire "loop" or closed figure around an object, the Create Path tool is a little more relaxed. All we have to do is create a path that ends up near our starting point. When we finish making the circuit around our flower, just before we might decide to "close" the loop by clicking on the first point, we stop.
Next, we click on the
Create selection from path button.
Next, we go to Edit and choose Clear.
With the selected portion cleared, we have a picture with a "hole" in it.
Now we can turn off the selection path we've created.
We select the layer we want to colorize as blue.
Next, we go to Filter, choose Color, and Colorify
When the Colorify window opens, we click on the color we want, in this case, blue. From the preview image we can see that teh entire picture has been digitally dyed blue.
When we make the layers active and place them in the correct order, we can see that blue layer is visible through the "hole" we made.
Our two layered image is complete. Now all we have to do is save our work.
