Get your screenshot on an shiny iPad mockup with a fancy professional canon camera next to it on a granite countertop. You can select 2048x1536px or 1024x768px  for your screenshot size to get the best resolution. The canon has a cool telescopic lens attached and a handy strap folded behind it. The iPads edges have a great reflective touch to them for the most authentic look. This would be great for a photography app.
