Use 35mm in a 220 camera to make paranoma pictures

[Philip Wang <pwang1@xxxxxxxx>]

Does anyone care to comment if it is feasible to use 35mm film in a 220
film back of a medium format camera?

It may be possible to take paranoma pictures 120/220 cameras if the 220
film back works with 35mm films. The only additional modification needed
is to cover the approprieate part of the viewfinder window to make
composing pictuer easier. Roll 35mm film into a 220 film holder is easy,
and need to attach 220 film lead to the begining of 35mm film. 

Here is the ratio for 6x6, 6x7, and 6x9 cameras:

6x6: 24x60mm, 1:2.5
6x7: 24x70mm, 1:2.9
6x9: 24x90mm, 1:3.7

I saw an example of adapting 35mm to 120 film using Russian Lubitel 120
camera. The advantage of using 220 film back is when rolling your own
film there is less paper back needed - just need the lead and trailer
paper, about 35 inches.
