Create a Backdrop Layer
Now we will create a new background for the image. We want to create a backdrop, over which we have
the most control, allowing us to adjust the value relationship between the foreground and background by
adjusting the levels and gradient of the backdrop image. This will be very helpful as we work since you may
find that you need to make changes to the background to make the figure more visible. It is harder to do this
if the backdrop is part of the same image as the figure or if the background is just a simple gradient bitmap.
