Imperial Exposure Meter

Meter and InstructionsI’ve had this little booklet in my drawer for a few years and decided to find out a little of its history.  In this modern age of digital photography where most of the thinking is done for us by the DIGIC6 or EXPEED4 processor, I think it is still beneficial to understand and remember the roots of photography.  At least for my own photographic journey, the more I learn and experience, the less of a reliance I have on the technology, I use manual modes more often, I turn off many features and I use single-point focusing.
