Started taking 3D photos in the early 1970's with a beam splitter. Moved on to full frame sequentials and finally aspired to an RBT camera in 2002. Used a variety of old stereo cameras along the way such as Kodak, Fed and a few others.
With the coming of digital I tried simple sequentials again, followed by a few twinned digital cameras. My personal favourite of these are the Stereoscopic Society (Coventry group) twin Sony Cybershot DSC-W200 supplied by the late Co van Ekeren.
