Time to Dye

One day exposure!

I've been having really, really good results from the more dilute dyes, the ones with much higher levels of alcohol than normal. They're exposing in 1-2 days instead of 3-7 and still retaining good detail. Turmeric exhibits the same issues of color visibility, but the rest are working really well.

The problem with turmeric used by itself is that the resulting image is so yellow that it's hard to see. A slight hue shift in post-processing can make the image dramatically better simply by reducing the amount of yellow by about 10%, moving it to a more orangey hue. The same result can be achieved in the anthotype itself simply by including about 30% sandalwood in the mixture, or a light coat of blackberry juice on top of the turmeric.

10% more orange

Blackberry juice with lots of alcohol (about a 2:1 alcohol to juice mix) is, as I've mentioned before, green. This green dye produces a very fast exposure; I got a perfect exposure with visible detail like leaf veins in just one day of bright light. One day. That's mind-blowing for anthotypes.
