For plein-air painters - that's French for "open air" - creating a work of art can be tough. Even just pronouncing it. Some say "plane air."
"The French call it 'plen air' – 'en plein air,' actually, and they are the ones who coined the term," said plein air painter Danna Hildebrand.
As a retired professor of 28 years from Sheridan College in Wyoming she would know, though she won't fault you for mispronouncing it. Pronunciation is the least of the challenges artists face when they hit the trail with their easels.
