Ok, I've got a 7d and a 24-70 L. I'm new at photography. I'm having the hardest time getting the whole comp in focus. I know this has to do w my fstop. I mostly shoot a lot in doors, hand held. When I set aperture at like F11, my shutter speed drops and it's hard to get the right exposure. Being that I have to shoot hand held and I know I shouldn't be below a 1/30. I raise Iso to 6400 and still sometimes it's not enough light. I only have the onboard flash. Any wise words for a humble beginner. And I can't really use a tripod. Im a graphic designer at a hospital and I have to go shoot surgerys and such and I have to be able to move around quick, thus can't use the tripod.
I think I would talk with DOC beforehand. The last thing I would want as a patient- on a surgery table- is to have Doc or someone else in the operating room distracted by camera flashes.. Oops, he just severed an artery when he was surprised by the flash... Nope- talk with Doc first.
