We were taught how to use two medium format cameras and light meters.
A light meter looks like this : http://www.wexphotographic.com/webcontent/product_images/large/216/1006844.jpg
The large white object on top of the light meter called an infra-cone this can slide to the left to reveal a sensor. The sensor gives a reading of the light that comes directly into the sensor, the infra-cone over the sensor gives an average reading of the light coming from all around. The mode button switches between different kinds of lighting one may use. When pressing the mode button different icons will come up symbolising different things. The sun icon with the EV is light readings for a certain kind of camera. A sun icon on its own will bring with it light readings for the exposure or shutter speed, symbolised by a ‘T’ also the aperture or F-stop symbolised with a F. The other two modes involve using a flash. The ISO button will allow the person using a light meter to adjust the light sensitivity. These three things ISO, aperture and shutter speed all affect the amount of light hitting the back of a camera to make a photo.
The light meter aims to make a perfectly exposed photo, or as Ansel Adams describes it to be in the mid grey area of his zone system. The zone system ranges from zero to ten, zero is black with no detail and ten is white with no detail. Number 5 is the mid grey zone with the most amount of detail.
To take a basic exposure and get a ‘mid-grey zone’ photo’ try to get the light meter in the middle of the photo, so for instance, on the tip of the nose. To make a silhouette, the light needs to be behind the person or object, so one would point the light meter towards the light. Or to make the light extra bright, point the light towards the darkest parts of the photo. All the information from the light meter will allow a person to pre-visulise a photo.
Medium format camera, which uses 120mm film, which is bigger than a 35mm, the larger the negative the more information in the photo.
The two cameras we were taught to use are a Mamiya 7 and Mamiya RB 67.
The Mamiya 7 has two parts to it the camera body and the lens. The view finder is not connected to the lens so when shooting one needs to remove the lens cap. On the lens is the aperture ring and the focus ring. On the camera body is how to adjust the shutter speed, ISO settings, flash attachment, time release, film compartment and cable release. To change the film press the orange catch and press end of the other spool and put it at the other end. The tutorial video we watch is http://www.youtube.com/watch?v=mVEX9CgWC0o
The Mamiya RB67 has three parts: the lens, body of the camera and the magazine (where the film goes in). On the lens is the speed and aperture ring. On the side is the shutter release and how to focus it is on the side. When placing the film in compartment into the magazine the thicker roll should be at the hinge. Before taking a photo take the slide out and unlock the shutter release. The tutorial video is for this camera is http://www.youtube.com/watch?v=HwGojbjtg4U&feature=plcp
