Hi Annette formerly known as Ben
don't forget to keep taking the pills.
I will tend to snap anything I think will make a good photo. Often as your driving along you see a well lit scene but no where to stop and park the car or even worse no camera with you. I like to go out on a bike or walk as this gets rid of the parking problem. It also gives you time to be relaxed and think about the shot. I often take the approach of snap it first as you may never get another chance then if you get a second bite of the cherry think about if for a while. My focus has been on birds for the last 12 months.
It's mainly being in the right place at the right time in good light. Shots I've tried to make happen by forward planing have mainly failed. The light is wrong, it starts raining, its too windy, the subject has gone, its too sunny and so on.
