Thanks for the replies, Chan Tran. So, if I can summarise what I think you are saying: In your view the Nikon matrix metering sacrifices shadow detail in C41 colour neg and presumably B&Ws for the sake of getting slide exposures right at box speed. Was this a deliberate decision on the part of Nikon, I wonder and is it peculiar to the Nikon F5 or all Nikon models with matrix metering and are other makes who use matrix metering subject to the same "metering bias" towards slides or have other camera makers skewed their meters differently?.
What might constitute a high dynamic range in this context and in shots with this high dynamic range, shot at box speed can shorter development in the case of B&W take care of any danger of blown highlights? I appreciate that C41 does not have this development adjustment.
While C41 negative films usually have about a one stop safety margin towards underexposure, would this not take care of the problem?I note that in destroya's case, who partly agrees with your analysis, he sets his EI to 200 so only compensates to the tune of one stop. Effectively if 200 is the right speed then box speed is only one stop under exposed which is within the safety margin, isn't?
Does Nikon make any reference to the need to override the matrix metering in the case of high dynamic range scenes when using C41 film or B&W only? One of life's irony's may be that, given the relative collapse of slide film compared to C41 or B&W film, Nikon may have backed "the wrong horse" as they say.
This whole question of matrix metering has given me a lot of food for thought but this is my last thought/question for now.
Can I assume that there is no built-in bias towards slides in a decent reflectance meter such that in a scene with a balance of tones i.e. one that would balance our as zone V the Nikon F5's matrix metering will give an inferior exposure which will leave shadows in the grainy mud compared to a reflectance hand held meter in a high dynamic range scene?
