Hi. Does anyone have any experience with the Brightscreen Proscreen on their D3? I used the Katzeye screen on the D200, but unfortunately they don't make one for the D3. I'm wondering if the Brightscreen is a good alternative.
Getting technical a "bright" screen may not affect matrix metering as this seems to take place in the camera base - without any light passing through the screen. As far as I know spot and center weighted metering in the D3 etc take place at the front of the prism head. If a clear screen with extra light transmission is used it will cause spot and center weighted to under expose. It may also result in different readings between center and out spot or different center weighted percentages as clear screens tend to be brighter in the center, often with considerable uneven illumination when wide angles are used. Nikon have never said precisely how matrix works - if it takes some information from the spot and center weighted then a bright screen could also affect matrix accuracy. Back in the days of "simple" metering prior to about 1985 when manufactures supplied a range of up to 12 screens Nikon advised which alternative screens worked best with which lenses and what, if any, exposure compensation was needed. Digressing the need for entirely clear screens with cross hair focus for extreme macro or telephoto work has been made largely redundant by digital camera live view functions.
Photography is a bit like archery. A technically better camera, lens or arrow may not hit the target as often as it could if the photographer or archer does not practice enough.
