Firmware

This is software containing various camera control instructions. The EOS D60 uses the firmware for image capture and image processing. Although the firmware is preinstalled in the camera, you can later install the latest version of the firmware when it becomes available on Canon’s Web site.

Format

Formatting a CF card is the process of preparing the CF card to store image data. Be careful when formatting a CF card, because the formatting process erases all data stored on the card.

ISO Speed

An index number representing the photosensitivity of silver-halide photo film. This sensitivity standard is determined by the International Standards Organization (ISO), and is normally written as “ISO 100”, etc. The higher the ISO speed, the greater the sensitivity to light. Digital cameras use ISO speeds based on silver-halide photography.

JPEG

Joint Photographic Experts Group is a file format for compressing and storing color images. The compression ratio can vary, but higher compression results in lower image quality when the file is expanded (restored).

RAW

This is an image file format that saves the image as is when captured by the camera’s imaging element. It is intended for image editing with a personal computer.

Image compression, saving, and decompression feature lossless image quality. By using the bundled software’s image-processing features, you can create the desired image characteristics.

Red-eye Phenomenon

In a relatively dark room, where subjects’ pupils are dilated, the light from a camera flash passes through the pupil, is reflected by the retina, and causes the subjects’ pupils to appear red. Red-eye is particularly prevalent when the flash is close to the optical axis of the lens. Use the following procedure to minimize red-eye:

1Shoot with the Red-eye reduction function turned on. (The red-eye reduction lamp lights

before the image is taken, causing the pupils to contract and thus minimizing red-eye.)

2Shoot with an EX-series Speedlite. (The light reflected from the pupil will not be directed along the optical axis of the lens, thus minimizing red-eye.)

3Shoot from as close as possible (same effect as 2).

Shutter Speed

The camera’s shutter opens for a variable length of time to control the amount of light that reaches the imaging element. This length of time is called the shutter speed.
