Re: [APML] 1st BRC mosaic: heart & baby

Thanks Jon.
I am using a Toya vacuum camera on these but I used 120 film on these shots.
It is supposed to use 220 without the paper (or 120 with paper removed). I
used some 220 but that's the roll I had the blue monster on See:

I will try it again with no paper.
