2 Thursdays ago (June 3rd) we got to actually make things together and managed to somehow magically be gifted a sunny day from the photo gods.
We discussed word suffixes like phobic and philic in relationship to words they were already familiar with and how that related in a science context with chemistry.
We talked more about silver nitrate and silver crystals, how there is a latent image in the darkroom which developer helps grow the crystals big enough so we can see them. We talked about how the visible light spectrum is different wave lengths and how we can see some of them as different colours - we talked about rainbows, prisms and how black and white photo paper makes colours with chemigrams and lumes- not with pigments or dyes but by reflecting back only those wavelengths of colour.
we made our own photography developer using lemon juice and washing soda- then we talked about super addatives (multiplication of effect in phtoochemistry terms) by adding instant coffee.
we made our own fixer using what the origional photographers used- a basic salt that is commonly found for treating water to make it softer for fishtanks and pools.
we talked about fabric dying and using resists referencing Batik and then applied that idea to photo paper and made chemigrams exploring 2 different resists(being liquid-phobic).
we talked about Cliche Verrres and how they are the cross between printmaking, drawing and photography and then made our own which were printed using a solarising technique.
We also found plants and made accelerated lumen prints / or chemi-lumens with the plants the sun and the photochemistry we made.
We talked about the difference between photograms and contact prints
We also finally had you all make your chromas from your soil samples! (i'm really looking forward to seeing some of the photos your teachers took documenting- and yours too if you did take some please make a new blog post and add them).
I've got some snaps of you making things on my instagram here
