Flash Photography

The OM-PC is designed to provide "OTF" Auto-

matic Exposure with Olympus T-Series electronic

flashes. There is nothing to set since exposure is
determined by the sensors in the camera body

itself. You can even adjust exposures using the

compensation dial on the camera. Because it

directly measures the light at the film plane, it
does not allow for flash exposure error utilizing

the sensor built into the flash.

Such special techniques as bounce flash, diffused

illumination and ultra close-ups can now be ac-

complished with full automatic ease.

Combined with T-Series flashes, the OM-PC per-

mits flash exposure in three modes: "OTF" pro-

grammed exposure mode, "OTF" automatic ex-

posure mode and manual mode.
