Back in 2004 I did a number of 'shadow drawings' (see top image) which were hand-etched images on acrylic sheet - the idea being that when a light shone the shadow of the etched image became visible. As the light changed so the image became less or more visible. As part of my fade/erase/wash series I wanted to do a similar thing with finger marks. Had a bit of a play today with a small piece of test acrylic and I think it will work - although of course it's absolutely impossible to get a decent photo. One dilema is scale - the old ones are about 90 x 120 cm so much easier to draw, see and document - these test are only about 6 x 10 cm and really tricky to draw. However I do quite like the idea of the scale being similar to actual size as when there is no direct light they look almost invisible - similar to finger marks on windows/ mirrors..... Will need to give this more thought - as I've still got a few months work to finish current large drawings there's no rush. Organising a group show at the Crompton in July where all customers/ staff can submit work - so may try to finish this small one for that - can get some idea of how it works and some feedback :)
