In this exercise we are going to take our base calculation.…And we are going to apply a couple of contrast iterations, one of which will be…designed to accommodate the larger mask and the other of which needs to…accommodate this area of low contrast over on the left side of the woman's head.…I am going to start things off here in the Channels panel by grabbing the one…and only Alpha channel and making a copy of it, so that we can come back to the…calculation if we need to in the future.…Then I am going to increase the contrast of the image using the Levels command,…so I will press Ctrl+L or Command+L on the Mac to bring up levels.…
And I am going to increase the darkness just a little bit here so I am taking…the black point value up to 20 and I should actually move this over a little bit…so that we can see these areas of jet-black in the background.…And that's pretty important, you may figure, oh gosh, this region over here on…the right-hand side was already pretty darn black.…In fact, if I take that value down to zero, you'll see if you look closely that…
