Bill Opfer practiced painting as a hobby throughout a long engineering career for the U.S. government. He learned some basic techniques from his late wife, who was a full time artist herself.
Now retired from the government, Bill paints realistic wildlife watercolor portraits as his new vocation. After experimenting in various illustration mediums, watercolor won out because of the way it shows the soft texture of animal fur and feathers.
Using his own photographs for reference, he paints native songbirds, waterfowl, butterflies, small mammals and large game. He has painted a number of pet portraits of dogs, cats, exotic birds and horses. One customer commissioned a portrait of a Black Angus cow!
