       | Thanks to Ansel Adams we have the Zone System which I use to
       | accurately set up my exposures in manual mode to cover exactly
       | the part of dynamic range of my camera that I want.
       | 
       | With some training I can set my exposure to within 1/2 EV within
       | 2-5 seconds (depending on how many parameters I need to change)
       | which means it actually saves me time compared to built in meter.

           | No, you use a spot meter for the zone system, generally.
