Christina...
My exposures are approx 2 1/2 to 2 3/4 minutes in the sun (unwavering bright, cloudless So California sun, mid-day).
It takes about 10-15 to see pigment in the water.
Negs are made with an Epson 3800 and its Ultrachrome 3 ink set (standard) and using QTR as the RIP.
I should mention that I found out how to reduce density with QTR last night, and will be trying that in the next few days.
I use WN Cadmium Yellow Pale, Sennelier Bright Red, WN Pthalo Ble GS pigments on Fabriano EW 140 lb.
Gum mixture is: .6g pigment / 9ml gum to 12ml pot dich (13%)
I also should mention that my intention is to get a full rendition 3 layer print, a la Keith Taylor (those are his ratios above). I've read his Ag article (available on Lulu for a pittance) and also there is now a great feature in the May/June View Camera.
Thanks!
Paul

How long is your exposure, Paul, and when you put it in the developing water, does it "stream off" the image area immediately or gradually?
How do you make your negs? What printer, ink, etc.?
Chris

Hello everyone...hope you had a nice weekend.
I tried another 3 layer gum print (same image as before) and althought the colors are better than the last time I did 3 layers only, I'm not getting enough color down to give my print a nice strong density. I'm getting good strong color in the clear borders...
I'm getting good clearing in approx 20-40 minutes...
My guess is I should be using a less dense negative. Do you all concur?
Thanks to everyone for your help...
Paul
