Have you heard about Tefal pans with red circle in the center called Thermo spot? I bet you do! But how about pictures with thermo spots? Grab a Lubitel 166u + 35mm film and i will teach you how to do it.
Well this trick is really easy to make!
As you all know Lubitel 166u can be used with to formats 6×6 and 6×4,5. Set your camera on 6×6 that means 6×4,5 must be closed. Then, turn the red window circle to the center between 6×6 and 6×4,5 and leave it there. DO NOT cover frame counter windows, just leave everything as it is. Load a 35mm film, wait for a sunny day and go out to take some nice pictures with thermo spots in the middle!
