- Make sure you know how to lock exposure (Usually by operating an “AE-lock” button)
- Turn on “Spot metering” (To allow “single spot brightness” metering)
- Dial in “-2” for exposure compensation. (By this converting Zone V to III)
Note that a camera like the Nikon D300 has a setting allowing AF to be moved over to an “AF-ON” button, a similar settings is available on an e.g. Nikon F100 too.
- Place your AF-point on top of the darkest part of your subject, where you still wish to have texture
- Activate AE-lock there (you press the shutter button halfway in with standard settings)
- Recompose and take photo
- Check the histogram of the photo,
recompensate and retake if very dark (left side adjusted) or light (right side adjusted).
