After four consecutive weeks of run and gun photoing, I'm sill in recovery mode as I write this. The past weekend was without an assignment but it's never like I have nothing to do. I still have rodeo photos I shot at the fair to post process. A photojournalist's fun is never done.

Rodeos are a challenge to shoot. Bucking broncs and bulls are difficult to predict. I try to anticipate the animal's direction and start pointing the camera in that direction expecting to get the money shot. I guess wrong a lot, thinking the animal will go this way but it goes that way. Grumble... grumble.

Another thing I try to accomplish is getting the bronc or bull rider in focus while getting the animal a tad blurry to illustrate it's action. Of course that requires getting the shutter speed dead on, Ha! Again I frequently guess wrong, but when I'm right... the image is spectacular. I get paid a lot for spectacular photos. You'll see the effect in a couple of the rodeo photos if you're observant... hint-hint.

Of course, timing is crucial as well as composition. It's important to keep the shutter button poised and ready. I get so upset when I'm a millisecond late. Must be that as I gracefully mature (ahem... age) my reflexes are getting a tad slower. My legitimate excuse for miscues!

As you know, pressing the shutter release button halfway activates the autofocus presuming that you're gear supports autofocus. But from my experience, the process is somewhat problematic.

Too many times, depressing the shutter button half way to activate focus results in two problems: 1) the shutter button is often too touchy... push it a tad too much and get a premature photo missing the money shot; 2) in the heat of exciting action, the shutter button often gets pressed in one swift push preventing time for the lens to focus. Hence, too many out-of-focus shots. Not good. Remember, an out-of-focus photo cannot be fixed!!! So, I gave up on that method years ago. Even for mermaid boudoir photography.

On my Canon 7D Mark II, I have the option of assigning an external button to activate autofocus. It's commonly called 'back button focus'. I designated the “*” button as my autofocus activator. I use the shutter button ONLY when I'm taking the photo. Before I actually take the photo, I'm pressing the “*” button on back of the camera to 'pre' focus so that when I mash the shutter button, focus is done and locked. Bingo: Money shot!

Even by the back-button focus method is not totally fool proof... especially when I forget to push it! But it's much better than using the shutter button to focus before taking the photo. If you have a camera that allows you to assign another button to activate focus, I encourage you to do so. It will improve your in-focus to out-of-focus ratio significantly. For those you who try it, let me know about your experience. BTW, it will take practice so that it becomes second nature. Just sayin'.

Panning... following a fast moving a subject in focus with the background blurred... is an interesting and creative technique. Set the appropriate shutter speed, aperture, and follow the moving subject. Rodeos provide such opportunities. Online, fillmoregazette.com, find and identify the rodeos photo where I panned the subject and the first person who emails me the correctly identifies the photo (it's also marked) wins one free Baskin Robbins scoop of ice cream.

I selected the 'leaping bull' as the “Photo of the Week” because I was amazed that an animal that large could jump that high.

Happy photoing!
