I'm on mobile, so I can't for a while, but let's see if I can recall offhand how to do it in PowerPoint.

Double click, go to picture options, find "fill", but click on "more fill options". That should bring up a new window with many tabs on the side, including one where you can turn brightness all the way down.

If my instructions were off or you couldn't get it, I can take care of it later tonight.
