The George Eastman Museum has opened a new exhibit, Photography and America's National Parks, this exhibit features images captured in various photographic styles, from Daguerreotype to Digital. So for the month of June we presented a series of videos produced by the museum that explain some of these photographic processes. Tonight we have our final installment in the series, this time we about Digital photography. You may think you know it's history, but my guess is that you're about to learn some things that you may not have known. Aired 6/3/16.
