“…If you’re saying in your head, ‘Oh, I’ll just fix that later in Photoshop,” stop what you’re doing and slap yourself as hard as you can.” –Zack Arias
If you’ve been reading my stuff for a while, you know that I’m a huge proponent of getting it right in the camera. Exposure, lighting, composition– all of it. As I tell my students, Photoshop is a tool, not a crutch. A bad photo is a bad photo, and no amount of post processing is going to miraculously turn it into a good photo. A good photo can very often be improved with a few well-placed tweaks and adjustments, but it’s just as easy to kill a perfectly fine photograph by going overboard in Photoshop. Still, though, photo editing is a fact of life and I think there are certain essential Photoshop skills that every photographer should know.
