I regularly sit at various cafes and draw people in my sketchbook. Recently I've been drawing people on my laptop with Adobe Photoshop using a Wacom tablet. I actually observed all of the people I drew in this video, many I didn't get to talk to before they left but the ones that I have photos of gave permission for me to display they're photo.
This is one of the best practices to do if you are into digital illustration, 3D / CG work, portraits, painting, live & figure drawing.
