This week, what does it mean to be a professional? Is it merely making a living from one’s endeavor or is there something else? Is photography something you need to do to achieve some greater sense of fulfillment, or is it simply a vocation? And is one more valid than the other? Also, we talk a bit about a new Van Gogh film that uses an oil painting for every frame. Ryszard Horowitz is our Photographer of the Week.
