Exposure meters

??? I take it you haven't used one then? The old ones have two usually concentric scales with exposure times ranged against f numbers - you read one off against the other. Modern ones are digital and if you set the exposure time they tell you the f-stop. They also, often, have the facility to store a number of readings and then average them out

The Gossen Sixtomat Digital is just like a camera, you can set either aperture priority or shutter priority and it gives you a straight reading of the other. Just one button to press to turn the meter on and take the reading, it switches itself off after about 5 mins. I use one because it's quicker than the camera, which I normally use in manual mode.
