Tyger sketches

[darktiste]

So on through the ctrlpaint traditional exercises...crosshatching.  Admittedly, this isn't technically crosshatching, but I had fun with it anyway.

I tried big light sources (a sky facing window), small/sharp light sources (bulb and sun), white surfaces, black surfaces, reflectors nearby...there's no end of possibilities!    

So here's a question.  Does anyone know where to find a good book or youtube videos or something for understanding value?  I've heard "How to Render" is good, but would that be a good choice for a beginner?

I recommend mixing Drawbox exercise with scott robertson book :Drawing and sketching from imagination with scott robertson and later on adding some :Scott Robertson - How to Render - The Fundamentals of Light, Shadow and Reflectivity
