I need to visit hundreds of websites and take screen captures of certain regions of the screen. The region is always the same aspect ratio. My process now, is to take a full screenshot, bring it into Photoshop and make my selection using a fixed aspect ratio and finally saving the image. It takes a while, considering I have to do this hundreds of times.
I've seen OSX utilities for taking screen captures (including the built-in OSX ones) but I'm looking specifically for one where I can capture just a area/selection of the screen AND (ahead of time) tell it what aspect ratio I want that area/selection to be. I simply want to press a button, move or select the area (which is already fixed at the desired aspect ratio) and then type in a filename to save it.
Does anything like this exist?
