Doing Cyanotype and Gum Dichromate at the same time.
For the Gum Dichromate prints, all are only 1st Yellow coat.
Gum Emulsion : a tiny bit of yellow pigment to 3ml of gum arabic and 3ml of Potassium Dichromate, which is enough to coat 3 A4 as shown. Leave them to dry naturally with a fan for 35 mins.
Exposure is 30 mins. Developing the prints were more tedious : following the instruction by Photographer's Formulary, each print 3 times (10 mins each) in water bath, but I soaked them for another 2 hours to clear the gum residue.
Compared with the tri-colour print I've made last week (8th round), the difference is the sequence of negatives used. This one is M - Y - C whereas the previous one is Y - M - C.
Verdict : I prefer the result of Y - M - C, which the lion looks more defined.
1st coat on 01 Jan - Negative from M Channel (bleached and toned with black tea)
2nd coat today - Negative from Y Channel (quick dip in bleach bath)
