In the past I have mostly used spot metering in many situations.
Matrix has been used occasionally and centre weighted has been pretty much only used for shots involving either on or off camera speedlight work.
Having used the D800 for a while now it is dawning on me that not only is matrix metering a lot more accurate ( in my opinion anyway ) to previous models but also that centre weighted seems to be extraordinarily capable under natural light conditions.
Down the beach the other day I was having inconsistent results with spot metering on a fast moving person in the surf ( all pretty much taken at the same subject distance and 200mm ) so i switched to centre weighted with an 8mm circle and the inconsistency went away. I think I counted 2 frames from about 100 that were slightly off exposure wise with centre weighted and around 15 out of 50 frames that were way out with spot metering before I switched.
Apart from the fact that this wasn't a jpeg from the camera, it may have well been along with a heap of others that were simply spot on and needed no tweaking at all.
Thoughts on the accuracy of the D800 metering modes?
