The light meter is in the bottom of the mirror chamber, and has to go through the semi-silvered central part of the mirror. This polarizes the light to some degree. In conjunction with a linear polarizer, this could lead to erroneous readings (leading to mostly overexposed film) if the polarizer is adjusted in a way that the two polarizations are at 90 degrees to each other. AF cameras also generally use semi-silvered mirrors, so the AF function is affected. Some cameras, such as some Nikon models, have their matrix and averaging metering done in the prism, and the spot metering in the bottom of the mirror box, so besides AF, spot metering is affected. BTW, I enjoyed you posts on HCB. I'm personally also not blown away by his photos, although I admire the way he developed and staked out the genre. On the other hand, one of my favourite photographers is Kertesz. His shots are maybe not quite as much 'of the moment', but for that the whole photo: the composition, moment and technique do a lot for me. * Henning J.
