    Default Exposure Quiz

    I'm giving this same quiz over on the Wild and Free forum right now (no peeking ;)). I like the way this preening egret is set off against the blue water. If you look at my tech specs, you'll notice that I shot this image at +1 1/3 EC. For the less experienced forum members, why would I do that with a bright white bird? Why aren't the whites blown?

    I would like to know what your meter mode was; I believe it does not work in evaluative mode?

    Jeni the exposure mode will not make a difference, the principle will apply to all :)

    Well picking up Arthur's book and it looks like this subject was shot in bright light with the sun at your back and exposure comp should be around 1 1/3 stops. " With a large brilliant white subject any background " ( and I quote), I guess otherwise it would read the whites as grey and underexpose, if it was set to anything less than what you had.

    The brilliant white is actually making the lens close up so you have to add more light..............and not really worry about the background?

    I agree with Jackie but I must say that in my very limited experience, it seems counter-intuitive and it doesn't come naturally to me, yet. Thanks for posting this, Doug.

    Try this experiment Katie. Take a frame-filling photograph of an all-black object. Then take a photo of a frame-filling white object. Take a look at the results, and share them with the rest of the ETL group.

    Default Exposing for Whites

    The following set was shot not even in bright light, although I tried to pick a reflective surface.
    All shot at evaluative with exposure compensation eventually ending up at +2. The + 1 1/3 was good exposure for the white, and for the black, too cool:) +2 started to peg the whites and the blacks.

    Good work, Jackie! I like your thoughtful approach and although I've know this information for some time now, I think it's finally sinking in.
