Cyanotype (6th Round) : More Tests

On Christmas Day.

At first the sky was pretty cloudy as if going to rain by the time I was ready to expose my prints but luckily the sun came out bright and shine for a short while before the sky turned dark again. I managed to over-expose all prints in one round (15 mins).




Tri color prints
Continue from last round,  I re-exposed the blue (using transparency from C channel). As suspected, they came out quite nice. Thus it is correct to say that I should wait for another day or two to let the paper dry thoroughly before exposing the last color, else the blue would came out weak or faded once dry.

In short :
1st step - Brown color
Coat the paper, expose with negative for the brown color, wash, apply toning bath, apply wash bath.
2nd step - Yellow color
Recoat the paper, expose with negative for yellow color, wash, bleach and then apply wash bath.
3rd step - Blue color (wait another day)
Recoat the paper, expose with negative for the Blue color, wash.




Two color prints

Also continue from last round.

1st step - Brown color
Coat the paper, expose with negative for the brown color, wash, a quick bleach, apply wash bath.

2nd step - Blue color (wait another day)
Coat the paper, expose with negative (single inverted B&W image and not the C channel one), wash, a quick bleach, apply wash bath.




Do not throw away those under-exposed prints.

I simply re-exposed them and the results are similar to two color prints.



Normal prints. Bleached and toned. Instead of pure black tea, I tried out with a mix of butterfly pea.
Verdict? I prefer the toned effect of black tea.
