In a way, yes, I would say that. Not necessarily giving it the name "PhotoReading", but you basically discovered a form of super reading and dipping/rapid reading. You may not have gone through any certain steps such as defining a purpose etc unless your purpose was to just sit down and enjoy the book. I would define it as more of a skimming technique, kind of like skittering, but without looking for specific information. If that makes sense.
