The Watkins Bee Meter - Early 1900s Photographic Exposure Meter

I was recently given a Watkins Bee Meter as a present (I'd been looking for one for a while), and it's such a cool gadget I thought I'd do a video about it.
The Bee Meter was invented by Alfred Watkins in the late 1800s, and continued in production until electronic meters took over. The Bee Meter uses light sensitive paper to measure the strength of the light - even in bright sunlight it will take a few seconds to darken to the same shade as a control strip next to the test strip in the measuring window - by counting how many seconds it takes and applying that figure to the exposure calculation dials, you can quickly (well relatively quickly for the time anyway) and accurately measure the correct shutter speed to set on your camera.
