Glossary Spot metering The meter reading is taken from a very small area around the center of the subject, defined by the spot metering area mark in the viewfinder. Spot metering is ideal for use in difficult light conditions, or when the important element of the picture (subject's face) is small. Use spot metering for backlit subjects, or sports and stage performers. See also digital ESP metering and center weighted averaging metering. TIFF (Tagged Image File Format) A format used for saving highly detailed black and white or color image data. TIFF image files can be handled by software programs for scanners and graphics applications. Non-compressed image data are stored in this format with this camera. TFT (Thin-Film Transistor) Color Monitor A color monitor constructed using thin-film technology. TTL phase-contrast detection system This is used to measure the distance to the subject. The camera determines if the image is focused by the detected phase contrast. TTL (Through-The-Lens) System To help adjust exposure, a light receptor built into the camera directly measures the light passing through the lens. 11 181 Appendix
