Cyanotype - 3rd Day






I was having this inner fight in my mind whether to take a nap after the early morning heritage trail or continue with my little project.  I chose the latter as the weather was undeniably nice with bright sunlight and no rainfall.

I need to finish up the printing of postcards before Christmas anyway.












The sensitiser mix was 7ml Part A Potassium Ferricyanide and 5ml Part B Ferric Ammonium Citrate (1.5 :1 ratio). The results were alright - strong blue and nice contrast.

I've tried out the other method that I came across somewhere online - first properly expose the prints (10 mins), covered them up for a few mins (3 mins) and then exposed them again (3 mins).  Look at those marked with a tick at the top right corner.  I don't see a big difference of the print itself. Guess need to do some more tests with longer 'dark-out' timing.

I Love Redhill

The Art Faculty
A platform by Pathlight (Enabling Village) that celebrates the abilities of people with autism and related challenges. A nice place indeed.

 



This Satay Beehoon from Redhill Market was superb.

No wonder the queue was damn long.

While Waiting .....

Saw this lonely old lady walked past while exposing my sun prints.

It’s so satisfying to enjoy an ice-cream in the hot evening. Some more it is almost at your doorstep. What can I ask for? Just eat lah 😋

Cyanotype (Continue Testing 2)





After the unsuccessful test last week, the outcome for this round is satisfactory.

Coating and exposing were carried out on the same day.
All single coat.
Exposure time was 10-15 mins.











This to show how the exposed prints look like.

The highlights and midtones turned a green/blue, while the shadows look slightly solarized.


Upon developing.



The paper I used :

- 300gsm Daley Rowney Aquafine Watercolour

- 300gsm Daley Rowney Aquafine Watercolour (New Quality)

- 239gsm MUSE Postcard PW-001

- 220gsm Awagami Hakuho Watercolour (though only 1 pc)






Paper - Daley Rowney Aquafine Watercolour (New Quality)
On Pic Left - equal portion of Part A Potassium Ferricyanide and Part B Ferric Ammonium Citrate.
On Pic Right (Marked with 2)  - 2 Part A Potassium Ferricyanide and 1 Part B Ferric Ammonium Citrate.

Paper - Daley Rowney Aquafine Watercolour
On Pic Left - equal portion of Part A Potassium Ferricyanide and Part B Ferric Ammonium Citrate.
On Pic Right  (Marked with 2)  - 2 Part A Potassium Ferricyanide and 1 Part B Ferric Ammonium Citrate.

With same 15 mins exposure, the 1:1 sensitiser produced more dense images whereas the 2:1 sensitiser produced more contrasty images, though the blue not as vibrant. May be I should test something in between.

Paper - MUSE Postcard PW-001
Same as above.  Those marked with 2 were coated with 2 Part A Potassium Ferricyanide and 1 Part B Ferric Ammonium Citrate. The paper was a bit yellowish and yet the blue came out pretty nice.




This was the only test on Awagami Hakuho Watercolour with 1:1 sensitiser.

I would say this paper is not suitable for Cyanotype. Because of its strong absorbent quality, it was hard to remove the yellow stain even I soaked it longer than the rest.

It also took much longer time to dry out as compared to the rest.






Definitely a good day for my sun print.
