[QUOTE="aroy, post: 307928, member: 16090"] Let me clarify. EV is EV that is not disputed. Unless a camera has an exposure meter which shows the light values in EV, you have to depend on what the camera displays. The camera display the Aperture-Shutter-ISO combination. That and only that. Change the ISO, the recommendation will change accordingly. What I had tried to convey is how to get the EV from what the camera displays. The Aperture-Speed matrix is dependent on two more variables a) The ambient light. b) ISO which is the film/sensor sensitivity to light. I hope that clarifies the matter. [B]NOTE[/B]. 1. Do not blindly rely on Wikipedia. It is written by mortals, and at times even reviewers miss out critical information (faux pax?). If in doubt to the veracity, I consult standard texts. [url=http://www.exposureguide.com/exposure.htm]Exposure | Understanding Exposure - ISO, Aperture and Shutter Speed Explained[/url] [url=http://www.exposureguide.com/exposure.htm]Exposure | Understanding Exposure - ISO, Aperture and Shutter Speed Explained[/url], here is a quote "some uses do publish EV as if it refers to an illumination level at ISO 100".
