I’m thoroughly convinced of this. I wrote about the #1 learning tool you’ll ever buy here. It costs about 5 bucks. It’s not sexy until you make it sexy. Mine’s getting damn sexy.
The second best learning tool only costs a dollar more and you can get it here. Or if you want the Nikon brand you can drop $24. Yeah. It’s a wireless trigger.
Why is this one of the best learning tools you can own? Because you can photograph yourself with it. You no longer need a model in order to experiment with lighting. And when you work with yourself as the subject there's no rush, no anxiety. But there’s more: if you are working with a model you can set your light levels before they arrive (provided you have a light meter... you do have a light meter, don’t you?). And there’s more: you can use it to reduce camera shake on long exposures. Yes, you can use your camera's timer for all of these, but the wireless trigger reduces the wait time and takes the picture exactly when you want it.
