In the mid-90s, Race Office & Art Supply closed their retail store on Main Street. In their clearance sale, they had three rolls of 1 inch x 60 yard 3M #235 Opaque Photographic Tape for a dollar apiece. I snapped them up. There are still about a third of two rolls left. I used it to make darn sure Little Guinness was reliably light tight. Coincidentally, Camera Casino is now in that store.
Shortly after loading the camera, I achieved a goal I had been pursuing for years. Stewart is a typical sun-loving cat but he can hear a tripod coming from across the house. One morning he was obviously concentrating on chasing mousies in his sleep with an occasional twitch of his legs and extension of his claws. I approached as near as I dared, made as few adjustments to the tripod as possible and opened the shutter for a one minute exposure.
