Holga 120SF + Polaroid backing

Oh the nightmare to get to this stage.

Long story short - even though I had the instructions, I totally missed the fact that the polaroid backing has a light sensitive plate you HAVE TO REMOVE before taking a photo.

So now I'm left with 20 shots left out of the 50 i had with the pack film's i bought ...

I'm definately going to use them wisely!
