Should Do

Thom has a list of things that photographers should do, but don't. It's a short list.

Use a lens hood.
Keep the camera body clean, not just the lens.
Keep shortcuts handy.
Carry (and USE) your tripod.
Walk there, don't zoom in.
Keep serial numbers with you.
Manipulate the light.
Read the manual.

Manipulating the light is a thing that I have not been doing as well as I'd like. I had some potentially good shots that I missed, because I did not use a flash. I'll be able to go back and try again, because they are landscape shots. I'll also try using gels on my flash, to further manipulate the light.
