OK so i guess if i understand this right on a really sunny day using ISO 100 your fstop should be as close to 16 as to make your shutter speed as close too 100 , the ISO speed , as possible? and if your shooting 200 ISO , a shutter speed of 200 is preferred etc etc etc?
SO i have questions
1. if this rule is so good...why doesnt my camera automatically try to get as close to f16 on auto or on Program on a sunny bright day?
2. i guess also as a guide your shutter speed should be equal to or greater than your focal point or zoom point....
Soooo if i am shooting at 200mm and my iso is 100 and obviously the shutter speed is gonna be too slow....SO is the sunny 16 rule even relevant in digital photgraphy still? Am I mis understanding it?
