A couple of weeks ago I went wandering about by the Cam at Ditton Meadows with two SX-70 cameras: a regular one and a Sonar. Regular had PX100 in it, the Sonar had 600 film.
It was cold, so the PX100 came out very pale, but magic seemed to happen with it. I love how the tree just looks like a tree in 600, but the PX100 lends mystery. And the river!
I had tried keeping the film warm in a cold clip (sounds contrary), but clearly not warm enough. I'm glad.
