Anthony another fine gum! How do you apply your gum coating?
Does anyone here use Da Vinci pigments?? they come in rather large tubes more suited to my needs.. I would be interested to know if they are comparable to Daniel Smith line.. most interested in the lightfastness aspect.
Thanks! Yeah I did! I work at a print shop and was curious as to how they made printing plates back before computers and stumbled across this process. I thought it would be fun to try out. The bridge took me 24 exposures (6 different attempts) to get right, and the still life took me 5 (I loaded one of my darkslides in backwards, so I wasn't sure if there was film in there or not, hence I took one extra as a safety). I also printed the bridge probably 20 times and the still life 8 times trying to figure it all out. So there was a LOT of trial and error involved. But I think for my next few attempts I'm going to go the single color negative with Photoshop curves and see how that goes. This method is just too expensive and time consuming.You went old school In camera separations , then re registered on multiple coatings and exposures.. I like the bottom skull image more than the bridge but quite haunting and good work.
Yes but you have learned how to do it the old school way and when you go the digital route, you will be so far ahead with your knowledge, I printed Pt Pd from 35mm to 16 x20 using ortho then enlarging, and I understand the more difficult way which in turn makes it much easier..Thanks!

Well, I did 4 color, not 3, so the black layer didn’t use a filter. But the reason it took me so many exposures to get it right is because I didn’t use photoshop curves to make my enlarged negatives. So I had to underexposed each shot and then over develop the negatives to give me more more contrast to make the negatives print well with the gum bichromate. Also, I used a cyanotype which didn’t need as much contrast, and the black layer didn’t need as much exposure or development since it wasn’t going to print at 100%, or it would make the final print too dark. So basically unlike a normal silver print, I had to make a bunch of negatives that look pretty horrible on their own, but work well together in the final print. I also had to vary the print times, development times and methods, and formula concentrations to get these to work. And even after all of that, they didn’t turn out much like how the actual scene looked.Why is this so difficult? Three shots should have been enough...
The red filter shot is made and using the filter factors to get the correct exposures bang on for the others...
Do I miss something here?
you can say THAT again !That looks fantastic Bob. Wish I could see them myself!
