This is the exposure meter that my dad used with the Akarette 35 mm camera that I drew yesterday. The Weston Master III Universal Exposure Meter was made in England by Sangamo Weston Ltd, Enfield, Middlesex and distributed by Ilford Ltd. This was model no. S141·3, serial no. T5385.
In low-light situations you flip out a filter at the back which is simply a plastic disc perforated with small holes. As you do this, the light scale flips over too. Taking a reading here on my desk I would have set the Akarette to 1/5oth of a second at f5 if I was using 64 ASA film, which is what I’d set the dial to when I last used this meter in the 1970s. ASA is referred to as ‘Weston Rating’ on the dial.
It was built to last, no batteries required and the photo-electric cell is still working fine, but I’m glad all of of all the exposure options that are built in to my current digital camera. The meter is bulkier and heavier than the Olympus Tough that I keep in my art bag.
