Bob, you just have too many cameras.
No, seriously, your work depends on having the right tool for the right application and naturally you are switching gears all the time. I can't imagine using the same tool or approach to solve problems every day in my business.
I understand completely where you are coming from - thanks very much for the comments - and truthfully I feel a little apprehensive about restricting myself in terms of camera/format rather than picking a single subject or some other theme to see how many ways I can approach it.
Maybe I'll blend both notions together and take on a series of themes over the year... hmnn... that's not a bad idea. I'm still thinking about what I want to do and appreciate the feedback. Rather than solely taking each day as it comes I'm going to come up with some sort of a plan to help guide things or rescue me when need be.
Apprehensive or not, I think it'll be fun for me. I've done the one camera one lens thing, not entirely successfully by my own appraisal, a couple times over the past year and actually enjoyed the restriction. Restricting myself to a minimal configuration certainly helps to ensure I always have a camera with me, but that's mere mechanics and I'd like to stretch a lot more over the coming year.
PS: You are going to miss monsoon rains - that was yesterday. Had to head out to the street to rake leaves up on to the sidewalk and clear drains lest the water run off down the street start flooding yards around here. Forecast for today is merely showers with breaks in between. Yay.
