It's summer so here are a few quick non technical tips for the traveling photographer.
-Always take less gear than you think you need. You won't really need it and it's a distraction. You probably won't need to walk around with a giant backpack, a tripod and 5 lenses unless your a birder.
-Don't be afraid to wander away from the obvious places. They yield non-obvious opportunities.
-Don't spend too much time looking at images of your destination online. It contaminates your vision and creates visual bias towards taking the same images as everyone else. It's fine to look at some photos, just avoid scrolling through hundreds.
When you're out and about the optimal kit is one camera and one lens. More than that creates opportunities for lost opportunities, confusion, and hesitation.
One Camera, one lens. Make it work.
