Exposure compensation and film speed

Fixed proper exposure

Proper exposure refers to the balance of light

and dark in a photo. When shooting a black

and white wall, the exposure will be based on the average ratio of black and white—thus the overall exposure is set for grey. This is technically called "fixed proper exposure". A good example of this is a subject with a strongly lit background. The reason the subject turns out dark is because there is more brightness than darkness in the frame. Therefore, the fixed proper exposure is based on the total level of light in the photo, which is significantly brighter than the subject.

In the case of strong backlighting, the exposure needs to be adjusted to compensate for brightness.

Adjusting exposure to accommodate lighting conditions is called exposure compensation. When ESP light metering is used, the camera automatically judges the light and compensates for the proper exposure, so manual exposure compensation is not needed.

Exposure compensation

With the IS-1, + / - 4EV exposure compensation

in 1/3 EV steps is possible. [+] compensation

will make a subject appear brighter, while [ — ]

compensation will make a subject appear darker. Under backlit conditions you'll want to make

your subject appear brighter (+1 to +2EV).

For shooting winter snow scenes, you may want adjust the exposure for additional definition (+2EV). Or, suppose your picture is composed of a black wall, ( — 2EV) compensation would most likely be appropriate.

Film speed

Film speed is listed on the back of the film package. ISO 100, ISO 200, ISO 400 are the most common. High-speed film (ISO 400), as implied by its name, is for taking photos of fast moving subjects, action shots for example. However there are other advantages to high-speed film. With high-speed film, such as ISO 400, you are able to take pictures in lower light. And the distance covered by the flash will be greater.

The camera is recommended for use of "DX"

film cartridges, ISO 25, 32, 50, 100, 200, 400,

800, 1600 and 3200. In the case of non-DX cod- ed film, film speed is automatically set to ISO 32. Also, films with middle speeds such as ISO 64, 160 and 1000 are automatically set to the next lower speed. When using middle-speed films, use the exposure compensation.
