Pluviograms

Pluviograms are contact copies of rain on photo paper. The amount of rain is recorded as a photogram. I exposed a strip of photographic paper (8x80cm) to rain at four stages using the darkroom test exposure method. First the whole paper was exposed for a certain period of time - e.g. 20 seconds. Then part of the strip was masked and the exposures continued in 20 seconds increments creating a range of exposures 20/40/60/80 secs. After the exposures I let the raindrops dry, scanned the negative and inverted it digitally into a positive image.
