One of the fun things to try with LF cameras are paper negatives, using printing paper. This morning I did an experiment with pre-flashing the paper by making an exposure (1/4 the 'taking' exposure) with a piece of plain paper in front of the lens (this is to reduce the biting contrast of the orthochromatic paper).
Chamonix 10x8, Symmar-S 360/6.8, Kenthene RC glossy Gr2, Ilford MG developer, V850 scans:
These were actually the 5th and 6th exposures I took. The first four were attempts at guessing the exposure, using two CFT lights and one strobe. I ended up taking these two with eight exposures of one second, and during each one second exposure the flash fired twice! Obviously my guess at rating this paper at ISO12 was, umm, inaccurate, as my flash meter had indicated that a single one second exposure would do it.
And to go from the sublime to the ridiculous, having spent the morning at that, I was inspired to clean up and take out my wife's Pen FT this afternoon. She bought it in 1978, and it must have been ten years old then, and hasn't been used for 35 years. The negatives are sitting in some Rodinal at the moment.
