3. Shooting

3-4 Exposures

When an exposure compensation is applied, a (+) or (-) warning sym- bol is illuminated in the viewfinder panel. It is important to remem- ber there is no numerical indication for exposure compensation. Note: Once the exposure compensation is completed in a photo ses- sion, do not forget to return the exposure compensation dial to the original "0" position.

3-4-5 AE Lock

The AE lock system is a useful tool to obtain the correct exposure on a limited portion of the subject area. Close in on the subject and point the camera toward the area where the exposure must be cor- rectly metered, then press the AE L button. The metering system of the camera stores the brightness level of that particular portion of the subject and displays an "AL" symbol on the LCD panel. The AE L button does not need to be pressed continually to maintain the metered exposure. The camera stores this metered brightness level for five minutes. To cancel the meter reading in memory chose one of the following actions:

1.Press the AE L button for the second time,

2.Change the shooting mode on the shutter speed dial, or

3.Turn off the main switch of the camera.

Note: If the camera is left unused for five minutes continuously, the AE lock memory will automatically be cleared.

3. Shooting 3-5 Focusing

3-5 Focusing

The Bronica RF 645 is a coupled-meter rangefinder camera in which focus is achieved by superimposing two viewfinder images obtained by two independent rangefinder windows.

1.Point the camera toward the subject so that the focusing portion of the subject fits into the focusing frame of the viewfinder. When the subject is not in sharp focus, two poorly contrasted, partially over- lapped images will be seen in the focusing frame.

2.Focus by superimposing the two images. As the focusing ring is rotated with the camera held normally (i.e. vertically oriented), one of the images in the focusing frame slides sideways in response to the lens movement. Rotate the focusing ring further until both images in the focusing frame of the viewfinder align perfectly.
