Below is an interesting article from LA Times regarding an
old LF camera in daily use for ID photography in Jaipur, India.
If I am not mistaken, he does the processing (i guess should be photo paper, not film)
inside (or behind?) the camera.
Here is photos of this camera from flickr.
The taking lens is Zeiss Ikon Tessar f4.5
Just wonder what type of camera is this and how old is
