The possibilities that lies in the ink linedrawing combined with a wash is amazing. To me one of the masters of that technique is Rembrandt. I keep coming back to his landscapedrawings with those delicate washes showing the balance of values and how he sets the mood to the scene with a few brushstrokes.
I will do more inkdrawings since there is alot to learn from it and it can be a quick and powerful tool when doing prepatory studies for any painting. I will have to try a few different inks to see which ones that works the best for washes, preferebly some deep brown that could resemble the original. I will have to do some researching and see what is out there.
