I've been painting outside lately. In my studio, I can't step more than four feet away from the surface to see the picture from a distance. The open air and more importantly, heat, has caused the drying times of my paints to reduce to almost nothing (nothing being an hour in this case). So I'm able to work on a part of the painting and come back to a dry surface, as long as I keep the paint somewhat thin. It's a nice way to work, if you can keep from dying of heatstroke.
