>>116565If you ever plan to do photography on anything except a camera with autoexposure modes and a built-in matrix meter that gives a neat +2, +1, 0, -1, -2 readout, yes, it is.
I don't know, I've been shooting with cameras that have no meter for the last fifteen years and have never had any need to know scene brightness in exposure values.
>There are meters that just give you the EV...
Everybody quit doing that 30 years ago because it was a huge flop with the meter-buying public. Nobody wanted a meter that spit out numbers that didn't correspond to anything on their cameras, nor did they like the extra step of converting EVs to shutter speeds and F-stops.
There are meters available that can be set to display in EVs, but you can set them to display in F-stop and shutter speeds, lux, foot candles, candelas per square meter, ass hairs per newton-second, and whatever other obscure units you might want. No remotely modern equipment will force you to use EVs.
I actually like the EV matching system on older Hasselblad lenses and don't mind working in the EV system at all, but that still doesn't make having exposure values in EXIF data useful information. It's totally useless once the picture is taken, then all that matters is the final shutter speed and aperture that the photographer chose.
