What do you do to be always ready for the next good shot?
I use A mode with fix ISO settings in my walkaround shooting. I don't use Auto because Auto mode always give me bright pics but not necessary showing the true scene.
Many times, I find myself shooting with aperture setting used in previous shots which is not most desirable for the next shot. For example, in the park, bright sunlight, everything is ok, then I walk under a tree/shade or when I shoot the passing by kids, I always forget to change the aperture settings. As you can guess, poor pics due to slower shutter speed and the hand shake. I find myself reacting to situation most of the time.
Any good habits to share? How do you always get yourself ready? Do you have a mental checklist that works for you?
