Here’s an interesting assignment for pros, emerging pros and enthusiasts: Shoot in Program mode for a day.
That way, for once you are not thinking about Aperture, DOF, drag, motion blur, and such. For one day, you will be thinking about your subjects, instead of about technology. And this makes some sense; One famous wedding pro even shoots in “P”mode, I am told.
You might try this assignment in the city, for some street photography. Or at some event. Either way, it’ll likely reset some of your thinking. And perhaps even open your eyes a bit more in familiar environments.
Have fun!
