One of my three recent classes concluded on Tuesday night. The subject was Framing and Matting. I pulled out my camera at one point so I could translate my notes later on this particular demonstration. And it happened to be the best photo of the day.
In this shot, the teacher (in black) was showing us one way to finish off the back of a frame. He had secured the photo in the frame with framer's points, then he used paper packing tape to seal the area between the foam core backing and frame, in order to protect it from humidity, bugs, dust, etc. Makes sense!
