    I noticed on Flickr image properties that some pictures have a 0/3 EV exposure bias. Is this the same as 1/3 EV? Sorry if this question seem trivial!

    Thanks

    I had the same question, and found this link, where multiple people agree that 0,3 EV means the picture is overexposed 1/3 of a step.

    Playing Scully to the internet that is Mulder, I then took a shot on my camera, underexposed 1/3 step (just to try and throw a monkey wrench into things), and uploaded it to Flickr. The exposure bias was -1/3 EV.

    Check the wikipedia article on "exposure compensation" for the actual mathematical formulas behind EV if your interested.

    0/3 i believe means you didnt use exposure comp, +1/3 means you used exposure comp and set it to over exposure by 1/3 of a stop...

    Algebra? Who needs it.

    0/3 = 0. Zero parts of three cannot equal anything but zero.
