digital photograhy camera, program?

Question

has anyone seen in reality tv, or anywhere, i see professional photographers having a big bar at the bottom of there digital cameras and i see a long cord connected to a computer. what is that bar and that cord called? do i need a program of some sort?

Answer 1

The bar is likely to be a grip which houses more powerful batteries and also has controls including a shutter release enabling the camera to be easily used when in portrait mode. The cord will enable pictures to be instantly downloaded to the computer and, yes, I guess a special; program will be needed .
