I have a GraphicLite D5500 lightbox , and was wondering if I could use it for flats. It has roughly a 10x10 inch lighting area. I photographed it underexposed to see how the falloff is on it.
I also have a 13x18 inch 1/8th inch thick frosted plexiglass sheet I can put in front for further diffusion.
Below are the box itself and with the plexi roughly 15 inches in front, exposed to see falloff. I used 28-75mm lens 75mm @ f/11 to minimize optical falloff.
Is this a usable setup to make flats? Thanks.
