Meters for photography show the ev reading of the scene computed for the iso specified, which varies, so if for a standard comparison, the term light value is converted to iso 100. You figured out the effective iso from tests in 1.) above, which may or may not be the iso indicated on the digicam. Basic functions completed, but bug exists. In evaluative metering, the camera breaks the image frame down into a number of different zones, measures the amount of light in each zone, and then analyses the findings to determine the optimal exposure.

Some cameras can be adapted, as i did to my plaubel makina 67, which simplifies their use with spot meters. Anyway, iso 800 meters 3 ev higher than iso 100, and the camera exposure will require settings 3 ev higher too. Then one set the ev ring on the camera; The pictures above are examples of how using the ev+..

In s/tv mode, since you set the shutter speed manually, it will adjust the aperture to compensate. As different cameras require pushing. Drop the shutter speed, and the little indicator will move to the right; Incident light from f 1.0 to f 128 + 0.9 stop; Therefore, ev0 is a pretty long exposure.

You can use the ev button in p (programed auto), s or tv (shutter priority) or a (aperture priority) modes. Ev 0 corresponds to an exposure time of 1 s and an aperture of f/1.0. In photography the ev or exposure value is a scale used for light measurements. A selenium meter is a light measuring instrument. An exposure compensation.
