TTL Direct "OTF" Light Metering
The OM-88 uses a direct "OTF" metering method which is suited for metering on a wide
range of subjects. It can measure the brightness of the subject directly on the film plane and
control the exposure on a real time basis. This method was pioneered by Olympus. Since it
can quickly react to any changes of light during exposure, it is convenient for shooting not
only stationary objects, but also fast-moving objects. It also simplifies macro photography
which has been considered difficult with regard to exposure determinations. Further, in
combination with T-series flash units (T18, T20 and T32 etc.) or an F280, it allows you to
take flash pictures easily in a fully automatic manner, including such sophisticated
technologies as bounce or diffuse flash pictures.
