Here's a definition on Wikipedia on what "Plein Air" means:
En plein air (French pronunciation: [ɑ̃ plɛn ɛːʁ]), or plein air painting, is a phrase borrowed from the French equivalent meaning "open (in full) air". It is particularly used to describe the act of painting outdoors, also called French: peinture sur le motif ("painting of the object(s) or what the eye actually sees"), where a painter reproduces the actual visual conditions seen at the time of the painting. This method contrasts with studio painting or academic rules; those might create a predetermined look. En plein air can also be used to describe other activities where a person partakes in an outdoor environment
I was able to attend on Saturday and Sunday afternoon. Most of the artists gathered around at the Historical Spring Arcade in LA, which has a nice shade and some nifty restaurants. I drank some Novellum Chardonnay from Crepes Sans Frontieres, ate crepe, and sketch-painted.
Just sketching on my journal...
A nice full weekend. It should be fun to walking around in LA on Thursday and look at all the art pieces... I haven't been to an art exhibit that I've participated in in a long time, given that I usually do digital work. This could be fun... might have wine there.
