The scene is important
I always try to create a scene of a real studio, so the chair, or table, is mandatory.
I think that a table prepared in white, the stirrups and a white and very bright light, are the needed things.
After some tries, I found the solution for the stirrups using two display monitor support to which I apply plastic leg holder on top.
Not the best, but they can be easily carried and may be applied to any table able to support the weight of the patient.
In the pics, my sttdio built up in my kitchen.
