Adventures in Spot Metering

I’ve bought a new photographic gadget (audience looks shocked - several people at the front faint with surprise and have to be carried out…..). It’s a spot meter. You use it to get the best possible results when you take a photograph. Film can only handle a certain range of dark to light. When you set the exposure of the photograph you want to map the range of the film onto the areas of light and dark in the scene that you want to see in the image.

You look through the spotmeter and it shows the light levels in a tiny portion of the scene. You get the levels of the dark and light regions and then set an exposure that will work over that range. I’ve started with a very simple approach. I’m just finding the darkest area and then setting the exposure to two stops below the reading I get from the meter. The spotmeter gives a reading assuming that it is looking at something which is grey. If I push that grey value down towards black I should get a sensible exposure.

I think I’m getting better
