White sub­ject

NPhoto - - Feature -

The sun­lit wa­ter­fall is clearly the most im­por­tant high­light in this pho­to­graph. A spot me­ter read­ing off the white wa­ter in­di­cated 1/125 sec at f/11. Any­thing white or nearly white, like this wa­ter­fall, is a per­fect can­di­date for Zone 7, so I opened the aper­ture two stops to f/5.6, plac­ing the wa­ter on Zone 7 – light, but not washed out. (An in-cam­era spot me­ter should in­di­cate +2, or two stops of over­ex­po­sure, for Zone 7, as shown here.) Note that be­cause I wanted to freeze the mo­tion of the wa­ter­fall, and depth of field was not a con­cern, I left shut­ter speed high and changed the lens aper­ture in­stead.
