Rotoscope
Rotoscope
Can you explain a little more about what you are doing? Are you working with an image sequence? What software, besides Photoshop, are you using for your project? And what are you trying to do with your images? Roto work can be and usually is extremely time consuming. You will have to create a tight fitting mask around the elements you are trying to isolate and there are no real easy ways to do that unless you shoot your footage against a blue or green screen. Then you would pull a key and not worry about rotoscoping. It wasn't clear by your question if you wanted to actually find roto shortcuts or apply the same effect(s) to a bunch of pictures.
