I have 2 set ups, one is for photography, this one is the set up I use for making my videos, first of all, here is the photo taken from my seating position
I have 2 soft-box lights for general illumination, these are currently turned off so the image doesn't flare, they are reasonably cheap (under £200 for 3 lights, 2 soft-boxes, one snood, a barn door and a set of filters.
Camera 1 is frontal shot, this is mounted on my tripod, and there's a multimedia monitor that I use for the blocking monitor (multimedia can be used for PC or direct video input)
Camera 2 is for overhead shot and is mounted on my small camera boom, this is attached to my portable DVD player on the desk as a blocking monitor, you can see the clapperboard in this monitor.
The microphone I use is a lavallier connected to a digital voice recorder.
At the bottom you can just see the multi-way power sockets.
Apart from the soft-boxes, I have the room lighting on (spot bar), and a desk-lamp with a 35W halogen lamp, most times I will point this lamp up at the ceiling to diffuse the light.
For editing I use Sony Vegas HD11, this allows me to add both camera tracks, plus the audio track from the recorder.
