I didn't do a B&W, but I did go out and paint today and I thought I'd share some of the things I tried from Marc's workshop. As he instructed, focusing on the value composition is my second thought after determining my concept. What a great lesson just with those two steps. The b&w and 4 panel studies definitely helped as I went back to do a color plein air. Today I used a lead primed panel for the first time. It is the L219 from New Traditions Art Panels. This is the panel Marc used in the final demo. I actually didn't like it as much as using his pumice powder recipe, as it was fairly slick and the paint came off sometimes as I was making marks. However, it does have a great look to it, and after some of the paint started to set up, it worked very well. I also used the Griffin Mixing White at the beginning of the painting which dried quickly and made it easy to work over. It doesn't cover very well and I was working on a ground, so I used Titanium White at the end. Using them in combonation this worked very nicely. You can see what I painted over on my blog, http://journal.donthacker.com.
I know the blog started with the B&W Challenge (obviously), but I would like to hear from the rest of the group in this manner as they reflect on/try other things from the workshop and even beyond (unless Jan thinks otherwise, she is the admin after all). I would be interested in what you guys have to share, especially since we know that we are working from a similar place, and I'm not sure how often folks will be working in black and white. I do plan to do a nocturnal black and white sometime soon, but I may have to wait until the days start getting shorter.
