When I purchased a Crown Graphic it came with Weston Master Universal Light Meter, Model 715, manufactured in 1939, I've learned. I've used it with the Crown Graphic, but too infrequently to tell whether missed exposure was my error or the meter's. This afternoon, I pulled out a compact point-and-shoot, set it to manual and compared the compact's (spot) reading with the Weston's. If the compact's reading is correct, the Weston would underexpose by almost 2 stops in the test I ran. If it's consistently off by 2 stops, that's easy to fix, of course, as I'll just quarter the ISO setting. But I wonder whether there might be something I'm missing, or whether the meter is just not working. Anyone else use an old meter such as this and notice a tendency to underexpose? Hope I can get it to work; a lot of fun to use old meter with an old camera. Thanks.
