I am reading Understanding Exposure... Peterson uses center weighted exposure measuring techniques, but suggests noobs use the superior matrix metering... He claims that matrix metering uses predefined algorithms to create the proper exposure... So my question is.... is there any point in using his metering techniques if one is shooting matrix? Techniques like taking meter readings beside the sun... or meter something green and back up 2/3.... If I use his technique should I be using center weighted metering?
