3. Shooting 3-2 Viewfinder 3. Taking advantage of a tripod or a monopod: The difference between sharp pictures and shots blurred by camera shake is one second away. When using a 100mm lens, 1/100 sec., is the limitation for holding the camera steady. A faster shutter speed is strongly recommend- ed for shooting with a medium format camera, since this unit is larger and heavier than a 35mm camera. If a shutter speed slower than 1/60 second is required when using a 65mm, a tripod or monopod is hig

3. Shooting 3-4 Exposures The numerals 1 to 500 on the shutter speed dial represent shutter speeds or exposure times expressed in reciprocals. In other words, "500" actually means 1/500 second and "60" is 1/60 second. The lens aperture can be set by rotating the lens aperture ring. The 65mm lens provides an aperture range of f/4 to f/32. Between any two f-numbers, there is an intermediate stop with the distance/aper- ture index line to set the aperture as required. 3-4-2 Exposure Metering System

3. Shooting 3-4 Exposures 3. Manual Exposure Control This exposure control mode is particularly important to those serious pho- tographers who intentionally determine specific shutter speeds and lens apertures in order to produce creative images. The Bronica RF 645 with its extremely precise electronic shutter speed and lens aperture control system makes an ideal manual exposure control camera. To set the manual exposure control mode (from "P" to "A" modes), rotate the shutter speed dial while p

3. Shooting 3-5 Focusing The image contrast will become noticeably sharp when the two images superimpose precisely. That is the point where the lens criti- cally focuses on the subject. 3. Split image focus: Split-image is an image divided into upper and lower halves. Human vision naturally perceives the most critical image matching when comparing the alignment of edges in a split image. The optical sys- tem of the Bronica RF 645 is so constructed that the sliding side image in the focusing fram
