Good article, Arthur.

You are right about different cameras working differently. I do not trust matrix metering very much on my E-1 (c.2003) and E-510 (c.2007), yet it works well on my E-30 (c.2008). Works even better on my E-M1 MkI (c.2014), and better again on my E-M1 MkII (c.2016).

I am always telling people that they need to understand how the metering modes affect exposure on their camera/s. In the case of Olympus, there are five modes - matrix, centre weighted average, centre spot, high key and low key. Also to understand when they should use each mode.

An understanding of how each affects exposure, then how exposure compensation affects each of the modes is a core competency in becoming a competent photographer IMNSHO.
