Special Advice To Professional Photographers Your Mamiya 645 AFDIII is designed for heavy professional use and will give you a long service life if properly maintained. Your camera and lenses have many moving parts which require periodic lubrication. Its electronic components, too, are subject to wear and tear and are affected by ambient conditions like dust, sand, sea air, heat and moisture. If cameras had odometers like automobiles, it would be easier to specify servicing schedules. [. . . ] Press the SET button or exposure metering mode button A to enter the setting. Warnings that the exposure is outside the metering range Program AE (P) The shutter speed and f-number blink. Aperture priority AE (Av) The shutter speed blinks. Shutter priority AE (Tv) The f-number blinks. Manual mode (M) The exposure metering value difference is displayed. Exposure Metering Modes Exposure metering is performed after automatically selecting average/spot exposure metering. · Depending on the subject conditions, centerweighted average/spot exposure metering is selected automatically, and the correct exposure is measured. · Spot exposure metering is automatically selected when the brightness of the spot exposure metering range becomes darker than the brightness of the entire screen. · If there is very little difference between the spot exposure metering value and center-weighted average exposure metering value, the correct exposure level is obtained as the intermediate value. The average brightness of the entire screen is measured, emphasizing the center of the screen. Average/spot auto exposure metering The time used for the metering timer can be changed. Custom settings (C-04 on page 93) Center-weighted average/spot exposure metering Center spot exposure metering The brightness of an area equivalent to 7. 6% at screen center is measured, and the exposure is determined. The circle at screen center serves as a general guideline. This mode is suited to measuring subjects with strong contrasts or measuring only screen portions. 61 62 Exposure Compensation In some situations, such as a great difference between the subject and background brightness or overall subject tones that will not meter correctly because they are all black or white, the resulting photograph may be under- or overexposed. When this occurs, use the exposure compensation function. Exposure compensation can also be used when you want to intentionally create overexposed or underexposed pictures. When exposure compensation button A is pressed, appears on the external LCD. When the front or rear dial is turned counterclockwise, the exposure is increased; conversely, when it is turned clockwise, it is decreased. The exposure compensation value can be checked on the external LCD or LCD inside the viewfinder. After taking the pictures, press exposure compensation button A again to return the exposure compensation value to 0. The exposure compensation value mark on the external LCD is cleared, and the exposure compensation function is released.
