According to photographer Ken Gonzales-Day, dabbling in such an array of moneymaking pools allows artists to discover which methods are the most lucrative. “It’s very difficult for artists to make a living purely off artwork sales. Sometimes they can get away with this for five years or so, but the demand is extremely unpredictable,” he said. Gonzales-Day is a professor of photography but he doesn’t rely solely on that salary. “I make about 25-30% of my income from other sources such as speaking gigs, public art commissions and publishing. None of these generates a huge amount of money, but it all adds up,” he explained.
