After banging around my Pentax spot meter a lot (did some damage to it) I thought I better test it before I did some important shooting. So today before work I shot 6 photos, this allowed me to test the spot meter, do some more 90mm tests (heads and full body shots), today's test also allowed to check out a recently found Grafmatic back. Everything turned out well, the meter worked bang on, the 90mm lens distortion on the heads and full body photographs turned out well (I like a bit of distortion) and the Grafmatic back did not leak light. I will take all this good fortune as a positive sign for the coming trip.
