So I mentioned this on another thread but felt it might be interesting, though I freely admit it doesn't have any of the trigger phrases in it, no dynamic range, OVF vs EVF, etc etc.
So many of you probably know and understand the way cameras meter and give a value for exposures, for many years if you took a picture of a defocused evenly illuminated monotone, irrespective of it's reflectance (within some limitations), you got a histogram spike around half a stop below center, the infamous 12% vs 18% variation. Well I have been playing with my cameras and I noticed that when I do that now I get a spike in the histogram that is centered.
ANSI standards, as I understood them, mean reflectance meters should be set to 12% grey, 1/2 stop below midtone, yet mine are now giving an equivalent exposure of the meter being set to 18%. I actually had both in camera meters set to -2/8 as I set them up when I got them and did cursory testing to set them there. What I didn't allow for was the fact that they don't seem to be behaving the same way as all my previous in camera meters.
Has anybody else noticed or have an explanation of this?
