    Default Exposure bias..Exposure compensation...??

    Hi, I know what is 'exposure compensation' on my cam, and I dial it up or down depending on my liking.
    But why is there another 'exposure bias' value in my exif. What is it? Thks..

    Eg.In this photo below,
    +0.67 is my exposure compensation right? Then whats the -1/3 EV. Confused why got x2 values.

    I think that should be the compensation level u have set when u took the photo. -1/3EV

    eg.

    photo taken with +2 compensation.

    Ok, you're right,
    1. The Ist 'Exposure' is shutter speed.
    2. Exposure bias = exposure compensation(that I dialed in)

    3. What then is the middle 'exposure' ar?

    Ok, Ok, tink I found the answer...

    The middle 'Exposure' is what I dialed in within post(Lightroom/photoshop).

    Thks, perhaps someone else will learn a thing new as well. Cheers!

    Apparently so, as according to someone who posted on a forum, will have to check my Lightroom at home to confirm.
