Bracketing protip with Mysets

    When bracketing for digital blending and expanded dynamic range there's no point in underexposing*. You want to only overexpose, to bring detail back into shadows. Underexposing does not bring any additional data. Therefore we would like brackets to be at zero compensation, +1 EV, +2 EV, etc. Since E-M5, E-PL1, and probably other Oly cameras can only do up to +1 and -1, you're only reaching one EV above and below with a three-shot bracket, and two EV above with a five-shot bracket. This is often not enough for scenes with wide dynamic range.

    Here's the protip - not my idea, can't remember where I got it from: for a three-shot bracket set exposure EV +1 in addition to the bracket, and save as Myset. That way you'll get three shots: 0EV, +1EV and +2EV. For a five-shot sequence set EV to +2, and you get 0EV, +1EV, +2EV, +3EV and +4EV - plenty of data brought back from the shadows!

    I set the 5-shot sequence on fn1 on my E-M5 and fire away. I'd prefer to take only two shots (0EV and +4EV) so this wastes a lot of shots, but it's better than nothing.

    Here's hoping that Oly will enable wider or even arbitrary brackets with as many shots as we want in a firmware update!

    * I don't know if this applies to true HDR, since I don't do HDR

    This very much depends on how you meter. If you spot meter the brightest thing in frame, then yes, you're right. If you use evaluative or center-weighted average in broad daylight you may well get blown highlights, and thus will want underexposed (-1 and -2 EV shots).

    Good point, fully agree. I expose-to-the-right.
