[QUOTE="Eye-level, post: 77188, member: 6548"] You have to know your EV stuff pretty good to do sunny 16 effectively. I'll try to explain...I know that with ISO 125 and shutter speed of 125 on a sunny day it will require f/16. The EV in this case would be 15. ISO 250 shutter speed 250 f/16 EV is one stop value in this case is 16 EV. Now what uses EV...your meter uses EV it is an old system actually known as guess what? Exposure Value System. I use EV because I know that outside in the sun at 125 EV is 15. Indoors under a bulb it is 9-11 depending on how many and what kind of bulb. Candlelit room is 3 I think but I don't tend to shoot in candle lit rooms so I am not sure about that. Intense bright light at the beach in the tropics the snow etc is usually way up there at 20. This is how I select aperture value and shutter speed when I use my F2 meterless camera and it has become so second nature to me that I do it with my digital camera with every camera I hold. :) [/QUOTE]
