It has been years since my last painting time-lapse and, as my process since then has changed a bit, I felt an update was due.
In general, I aim to make my process as direct as possible. I’ve pulled away from tight pencil transfers and tend to do my drawing directly with the paint whenever possible (I’ll still go to transfers for various situations, such as heavy architectural details) which needs a day or two to dry before I can more forward. This makes live demonstrations challenging. I’d usually show up with that part finished and dry so I can get to the interesting stuff, but here I am showing everything starting with the priming of the surface.
I should also note that, as in all of my work, I am painting from a photo reference and not a live model. I’d use this same basic approach for life painting, measurement checking and all.
