Setting on the six foot table is a piece of paper beneath a piece of cut, milky plexiglass. In front of the table is camera on a stand, which is about set about 2 inches higher than the plexiglass pointing down at a slight angle, toward the glass snail. The plexi glass hangs over the back of the table by about two inches. Behind the plexi glass hangs a diffusion panel, clamped to a C-stand. The distance between the plexi and the diffusion panel is about six inches. Behind the diffusion panel directed back toward the camera are two flood lights lowered to about 3 feet. They are about 3 feet apart, pointed at 45 degree angles inward toward the center of opposite sides of the diffusion panel (where the object will sits). The lights are approximately four feet away from the diffusion panel.
A piece of white cardboard cut to the shape of a mushroom is taped to the plexiglass, so it sits above the invisible horizon line.
There is a 1 stop difference between the object, the edge of the plexiglass, and the diffusion panel to create a seamless/invisible horizon line.
