razor

Remember the advent of multi-blade shaving razors? Single blades gave way to two blades and then three, four and five. There are even a six+ blade razors out there in case you want a REALLY close shave. Well, a fresh Canon sensor patent has us wondering if the same thing isn't happening to digital sensors.

Canon has patented a Foveon-like sensor before -- a type of sensor, initially implemented by Sigma, that uses individual layers for detecting red, green and blue -- but the company's newest multi-layer sensor patent shows not three, but five layers.

Photo fads are themselves growing as a fad -- after "planking" became a worldwide Internet sensation earlier this year, it seems like every week a silly new idea is introduced as "the new planking".
