The attraction of Iron Sulphate

I can’t believe its April already. Spring is well and truly here and its time to sort some fresh chemistry but First I thought I’d run some tests with some old chems on something I’ve been meaning to try for ages.

These are wet collodion plates processed with a strong Iron Sulphate developer, but I have introduced a magnet below the plate at the time of development and exposure.

Using a small but strong magnet placed centrally below a sensitised plate I poured on the Iron Suplhate developer and at the same time fired a small low power hand held flash, thus exposing the plate at a specific point of development. The results are amazing.

Didn’t work so well on aluminium plates.

I felt a little foolish trying it but so pleased to be able to share it today.
