Philippe, Moose, Chuck-
I just checked, and AE bracket, WB bracket and FL bracket are all off.
The exposure comp is always at -0.3 to help cut down on blown highlights.
There aren't any highlights that need taming in this shot, but one of the guys
has a lime green kayak that positively glows, and always clips when it is
anywhere near sunshine.
Usually when I shoot multiple pictures they are all exposed similarly, but
occasionally the first one will be darker. It's generally after the camera has
been sitting for a while, but I'm not sure how long of a pause it requires.
One other bit of data: If I turn the camera on and immediately take a picture,
it sounds like a picture has been taken, but the resulting image is entirely
black. If I count to three or four before taking a picture it comes out ok.
Judging from what I'm hearing, I'm leaning toward a camera fault. That is made
worse by operator faults.

Subject: Re: [OM] E-520 question
It sounds to me like you may have autobracketing enabled. (see page 50 of the
E-520 manual). Normally one would get three exposures... a base exposure and
then a negative exposure compensation followed by positive exposure
compensation with the exposure difference according to the settings you've
chosen in the camera.
Exposure 613 looks like the negative exposure adjustment while 614 looks like
the positive exposure adjustment. What's missing is image 612 which would be
the base exposure if I'm right about autobracketing. The bracketing process is
interrupted if you don't leave your finger on the shutter button long enough to
get all 3 exposures. It all hangs together for me except for missing image 612.
Ooops! I just blew my theory out of the water by looking at the EXIF data from
both images. Both say ISO 200, f/4, 1/800 sec, exp comp -0.3
Sorry, I don't have a clue. Is it repeatable?
