Leica M7の取扱説明書・マニュアル [全134ページ 1.37MB]

82Setting an exposure compensationExposure meters are calibrated to an average grey(18% reflection), which corresponds to the bright-ness of a normal, i.e. average, photographic sub-ject (for more details see the section "General information on exposure metering” on p.106). If the relevant subject details do not meet theserequirements, a corresponding exposure compen-sation can be carried out.Particularly for several shots one after the other,e.g. if a series of shots with a slightly lower or higher exposure is deliberately required for a particular reason, exposure compensation is avery useful function. In contrast to metering memory-lock, once set it remains effective until itis (deliberately) reset (more details of metering memory-lock can be found in the appropriate sec-tion on page 98).With the LEICA M7, exposure compensations canbe set at 1/3EV intervals in the range ±2EV. To do this:1. Hold down the release button (30), and2. then turn the locking dial (28) so that its white index dot is opposite the desired compensation value on the scale (27).The whole range of possible compensations of±2EV can be used for all engraved film speeds.Overall, the resulting extended setting range makes it possible to use speeds from ISO 1.5/3°to ISO 25000/45°.Any exposure compensation set is indicated in thecamera’s viewfinder, see the table on page 81 for details.Note: Any exposure compensation set on the camera influences both the metering of the available light and the TTL flash exposure meter-ing.
