Artists use matte varnishes to protect their paintings before they are photographed. In the old days, there was only glossy fininsh. The drawback to glossy finish varnish is that it makes it almost impossible to photograph the painting without distracting glare spots. The lush feel of an oil painting can be reduced however by the use of matte varnish. What’s a girl to do?
I’ll tell you what to do. Finish the painting in matte and shoot it. When the painting sells, ask the client what finish they wany. They may like the matte look. But if your client wants super gloss, tell them that it will take an additional 2 days to send it out and hit it with a couple of coats of glossy varnish. Varnish finishes go in and out of fashion, so talk to framers about which finish is current, always remembering to give the client what he or she wants.
