When I paint out of doors, I'm used to the lighting changing as I work. That is why I might come home with half a dozen unfinished works. When I set up in the art studio, I need to ensure that my lighting is consistent.

If you live in the Northern Hemisphere, then northern facing skylight windows in a sloping roof can direct superb natural light into an artist's studio without creating glare. You have to reverse that natural light source in a Southern Hemisphere studio, and light the room from the southerly aspect. Supplement that natural lighting with the best artificial light for your needs. Artists need light, but never glare on the canvas or off the wet oil paint.
