I recently got a new fuji back for my toyo 4×5 to replace my polaroid back (because polaroid is no longer making film).  The back is a lot bigger than the old polaroid back (because this one shoots a pack of film instead of individual sheets) and I was having a lot of trouble getting it to load properly.  So Paul and I decided to play with it tonight and we got it to work!  What a relief…I use it all of the time and with polaroid out of business I thought that I was just about out of luck.  Here’s our test shot.  It was a 4second exposure, so Paul’s a tad blurry.
