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). 38
