If you’re a fan of shooting portraits in outdoor environments, David Hobby of Strobist has a great tip: keep a catalog of spaces and backdrops that you stumble upon. Anytime you need a backdrop, just flip through your catalog and select the one you (or your subject) like. If you have a GPS-enabled camera, simply snap a photo at the various locations and throw them into an app that can display the locations on a map for you. There’s also a nifty free app called ShootLocal designed for this very purpose.
