TTV (Through The Viewfinder) photography is when you use an old medium format camera and a digital camera.
These old medium format twin reflex cameras have large viewfinders. Firstly you compose your image using the medium format camera (in my case i have used a mamiya c33) then you actually take the picture using a digital camera (here i use my pentax K10) of what is in the viewfinder of the old camera.
