Finished my first Bargue plate. It was very challenging trying to get the proportions and notional space correct. I'll aim for more accuracy in the next one. But it helped me a lot and I learned a few very important lessons.
White charcoal on grey card paper was great for rendering highlighted areas too, I'll stick with that technique. This one was probably a little too small physically. The Bargue plate print itself was only a little bigger than A4, but the next ones really need to be at least A3 just to be able to see enough detail and render it accurately in the copy. Anyway, onward and upwards.
