Experiments in Refraction

Last night at Toft Photogroup, we played with refraction and reflection using Dichroic cubes, CDs and Crystal ball and Cross polarisation.

Cyanotypes

Yesterday, I shared a day making Cyanotypes with members of Cambridge Camera club. Lots of fun was had doing both wet cyanotypes where various 'chemicals' can be added to the composition before exposing to the sun, and dry cyanotypes done on commercial precoated paper. As so often, it was the detail in some of the images before washing that took my eye.

Experimenting with Wet Cyanotypes

Before lockdown, we had plans to run a cynaotype workshop and had experimented making negative on film and printing cyanotypes on coated dry paper. I thought I would have a go at Wet Cyanotypes developed in the sunshine. Here are a few from the session showing the various stages and some results - more to follow. The things I experimented with were Clingfilm, turmeric, salt, citric acid and bicarb of soda. The images show some of the setups after exposing to the light with or without the objects in situ and before rinsing - brown coloration.  Once they are rinsed in water the prints are a blue colour.
