Exposure Meter Calibration and Readings
The Olympus OM‑10’s built‑in selenium meter provides instant exposure data via a needle on the viewfinder. To calibrate, first ensure the camera is set to the correct film ISO, as indicated on the rear of the lens or the camera’s front plate. Next, expose a test frame in a controlled lighting environment, then remove the film and examine the exposure on a calibrated densitometer. If the meter consistently reads over‑exposed, adjust the meter offset by turning the small dial located behind the shutter release button. This dial allows fine‑tuning in 1/3‑stop increments. For under‑exposed readings, reverse the adjustment. After each adjustment, retest with a fresh frame to confirm the meter’s accuracy. The OM‑10’s meter is designed to be accurate within ±1/3 stop when properly calibrated. It is recommended to perform this calibration at least once a month or whenever the camera is moved to a significantly different environment. Additionally, the camera’s internal light‑sensing element can be checked by placing a neutral‑density filter over the lens and verifying that the meter needle remains centered when the camera is held at a known distance from a light source. Proper calibration ensures reliable exposure decisions, especially in low‑light or high‑contrast scenes.
Regular calibration ensures accurate exposure, vital when shooting high‑ISO films or in fluctuating light during rapid sequences. daily.OK
