In school we always started life drawing class with one minute poses. Sometimes up to forty of them. It is an excellent way to sharpen your drawing skills.
Now I make it a point to do warm up sketches before I start oil painting.
However this is a little difficult if you want to sketch horses, they just will not hold still!
But if there is a will there is a way, I set the slide show on my computer for 60 seconds .
If I am sketching a horse and rider, like the one above I will set the slide show for two minutes. It works great!
I still find it very help-full to do oil sketches out in the pasture for the color and value information, but I believe the photo's work better for shape information.
