My studio/office is set up in a 18 wide moble home. The main living area is my main shoot area which the inside measurement is about 17 X17 feet. When I need more shoot distance I also use the kitchen area for the camera. This set up you see here was I used to take the self portrait that you see on the home page of this site.
This is my office where I do all my imaging processing. I have a dedicated computer for just imaging processing that is a dual core 4200 AMD with 6 gig of memory. I also have the front bath set up as a model change area with balance daylight lighting for doing make up.
