Topic: Practical Application for "EV"?

[6cmsquare]

Ok, so I in the midst of reading Ansel Adams' "The Negative" and the Zone System immediately makes sense to me, -matter of fact I walked around all day looking at things and visualizing them as "zone V + 2 stops" or "totally zone II"  however, -regarding the EV#, I'm struggling to think of a situation where knowing the EV# of an exposure would help, being that an EV# can be equal to any number of f.stop and shutter time combinations.   

Can someone enlighten me on a situation where calculating the EV is applicable?

I have two cameras that have counterrotating shutter and aperture controls on the lens barrel, and are marked with EV. What I like about it is that I can use sunny/16 or meter, adjust to the matching EV, and then make a shutter speed or aperture selection but rotate both rings simultaneously and maintain the same exposure.

If you use one of Francois' infamous paper exposure meters (such as http://expomat.tripod.com/), they're always marked with EV, which makes "cheating" with an EV-marked camera easy as well.

To be honest, I never really got the value of only using EV in my metering...
I know it can make things supposedly more easy but I just don't get it...

I use it to count steps from sunny-16 (or sunny-11, or whatever I'm using at the moment), assuming EV15 as the starting point. Quick and dirty, but it works pretty well for me.

If you plan to ever shoot with a vintage Polaroid camera...youll love EV. In fact, most of the models exclusively have EV settings and nothing else.



The Polaroid #625 exposure meter for these cameras is also an EV only device, makes using them with a Polaroid camera a perfect match.

Even the high end 110A/B models with their Prontor manual shutters have EV marks on it for quick, no thinking, exposure setting.
