Taking Photographs (III)

— Automatic Exposure —

In automatic exposure, the same picture will be exposed with a very different exposure

value if it is taken in different backgrounds. The OM-4T has an exposure memory lock

system to solve this problem. It can be used in both the TTL direct metering and spot
metering modes. Once an exposure value stored in memory, it does not vary even if you

change the aperture (or shutter speed).
