I just bought a GVII (my first LF camera) and would like to use a darkcloth instead of the "viewer" thing on the back. I don't know how anyone can use a loupe with that thing attached. My mother is a seamstress and is going to make a darkcloth for me. She is going to put elastic on the camera side with some velcro on the bottom to seal it up a bit. She is going to make it black on the inside and white or silver on the outside. How long should it be? I would think that if I could get my face about a foot away from the GG and still be under the dark cloth that might be plenty, but I'm not sure. Any tips on making my own dark cloth?
