I have several examples of this where the background is in perfect focus and the subjects, me and my buddy, are out of focus, framed incorrectly, not zoomed, etc...
Most folks have a digital camera of some sort or another; a few even have an entry level DSLR. I have yet to see any of them carry their camera's or pull them out to take a photo. When I ask them where their camera is the constant answer I get is "in my desk/closet at home." If you own a digital camera, get it out and some fresh batteries in it and start carrying it with you. You will enjoy looking at the photo's you make in later years and can even have fun posting them to the web.
I was finally able to teach Sergeant Maxon how to focus lock and recompose after about 5 minutes and 20 frames and here's how he did.
Not too shabby I'd say.
This post was supposed to be about focus/exposure lock, but it took off on it's own path. I'll do that post next.
