The method I am about to describe can help you take excellent screenshots that look like sketches of whatever you are looking at. First, go into a game and throw either a frag, plasma, or firebomb grenade near whatever you want to take a "sketch" of. Then, go into theater mode and move your camera inside of the explosion caused by the 'nade. The screen should be entirely white. Then, slowly move the camera to the outer edge of the explosion. If done right, this method will make it so that the outside world appears a sketch. I would attatch some examples of a sketch screenshot, but I'm relatively new here and am not sure of how to do that- can anyone help me out here?
