This is my first attempt at a TtV. Just for fun I put my Argus 75 on a Tripod and shot through the viewfinder using Super Macro with my Fujifilm S200 EXR without the use of a TtV contraption.
What's a TtV?
Through the Viewfinder. All you need is a old TLR camera like a Kodak Duaflex or a Argus 75 and a digital camera with macro. You focus digital camera over the viewfinder of the old TLR and magic, you have a TtV photo! It's modern meets old school! Here's a cool tutorial [link] I shot this without a contraption, but I'm going to try to build one over the weekend out of black mat board. Do a search on DA for TtV, there's lots of cool stuff being done!
