Re: First tricolor gum

[Jim Larimer <jrlarimer@gmail.com>]

Paul, the blue may need to be more saturated, but if you look at the borders you seem to be getting fairly saturated color. Perhaps your negative is a bit too dense? And, I really don't think that you need to develop for much longer than 5, to 10 min max. When I develop for as long as 60 mins, my prints are very washed out and thin. Just guesses. But, for your first tri-color I think you have done quite well!

OK, I tried a tricolor gum today with the intent of getting true color. Using 1:1 gum/dichromate ratios and sun exposures of 3 minutes and 30-60 minute development, I ended up with this:

My guess is that I'm not putting enough pigment in my mixes...especially the blue pigment.

 

I used Prussian Blue, Warm Sepia, and Anthraquinoid Red...all Daniel Smith watercolors.
