Let's hope the weather stays lovely this week as our challenge needs bright sunshine and a lot of patience! An anthotype is an image that is created using photosensitive material from a plant. The process was originally invented by scientist Sir John Herschel in 1842. It is one of the slowest and most natural ways of photo printing. You only need a plant pigment, a piece of paper and the sun. Essentially, it is sun bleaching the colourful pigments that you’ve coated the paper with.
You will need a plant with a strong colour - spinach is good, blackcurrants are supposed to work well (although I have never tried them) - in fact, anything that stains when you spill it should work!
Spinach works really well because it doesn't take long for the sun to bleach the colour out of the exposed parts of the paper. Beetroot is quite good because it has such a lovely purple colour, but it can be very tough to squish up. The lady in the video used a sheet of perspex, but you can use a piece of acetate saved from some packaging and it will work just as well.
Have a go and experiment, just remember it takes a long time in bright sunshine! We'd love to see how it goes!
Don't keep your finished anthotype in a sunny place, keep it in the dark or the bleaching process will carry on and your print will disappear!
Don't forget to share a photo of your creations on your Dojo portfolio!
