Hi Katherine J Gillis! Welcome to APUG.
Where to start?
How do you know exactly how many drops of the different colors of Spotone it will take to match your prints? I keep thinking I am close and then when I look at the prints in the sun I can see the spots are more blue than the print. It's "fine" but I sure would like to get closer to a perfect match.
Is it better to work with a 20/0 brush and dried spots of Spotone? I dapple a palette with different concentrations in each bowl so it looks kind of like the surface of a golf ball with lots of small dots of dried dye. Then with slightly dampened 20/0 brush, I touch a spot of dye and then the print. I get about 2-3 spots on the print just right then have to go back.
Or is it better to have a larger brush like 000 and work wet? Is a fine sable brush necessary or can any student-grade brush do the trick?
How about negatives? I always thought it would be great to have some kind of syringe needle to pinpoint a tiny dot of opaque over a pinhole on a negative. But haven't yet been able to reliably spot pinholes. What's the secret?
