While on the topic of blue..., isn't it a sad physical and economic fact that those blue tarps don't last worth a damn? They cost good money yet getting much more than a year out of one is like asking for sex--just doesn't happen. I like to think of them as large surface area duct tape. I'm starting to think that maybe constructing duct tape tarps would be cheaper and would last just as long. Am I on to something? Does anyone care? I take the majority of my photos with film. THAT'S economical! So what gives with my duct tape tarp logic? I don't understand myself.
