Usually what you get from the Tunnelvision Lens is a blur effect on the edge, like stretched and focus on the middle, or you could do a macro shot. Yes that's the usual view from this lens, but there is another view. It is shadowy, mystic, surreal, when I see these pictures. It's like multiple exposure, but when you pay attention it's not like two frames merging into one frame. Yes this is another view that you could get with tunnelview lens from lomography.
Now, how do you acquire this kind of pictures? Firstly for the freedom of movement, you might want to use it with your SLR camera. It is more convenient with big ring lens above 55mm.
What i do is to put the Tunnelvision Lens on the ring filter of my lens, for easy exposure, try to get focus first, then put the lens on the filter, and move around the filter until you get what you want.
But how about if you use a small ring lens, what you could do is to hold the Tunnelvision at the front of your lens, and do the same thing until you get what you want, of course get focus first.
Well, what kind of response from the DSLR user after they see your picture, they will say NICE editing, wkwkwkwk, but don’t get mad to them what you could do is say to them, NO Edit!
Ps: As usual, Have Fun, dont mind my tipster
