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.
