I own a Nikon D300 and am having problems with the exposure. It seems to almost have a pattern to it. Whenever I take pictures the first couple are always extremely bright followed a couple good ones and then dark ones. I can't figure out what's going on. Has this happened to anyone else?

  It sounds like your auto-bracketing may have been accidentally activated.

Check page 119 on your D-300 Manual to see how to set it back to "0" using the Fn Button and Main Command Dial.

  Sheri: Were you using flash for these photos?

If yes, then I know what the problem is.

You cannot use any aperture with flash ... well you CAN but then the exposure may be incorrect.

Photo 1 and 2 were made in P mode at wide apertures. So the images are fine.

But for Photo 3 you must have rotated the dial and set f/16 (see the data for all the photos under each one above). That is a very small aperture and minimizes the effective reach of the small built-in flash.

If you just use P mode as is, without rotating the dial to set a different aperture, most flash photos should be fine as long as you are not TOO far from the subject.

Cheers! Peter www.peterkburian.com

Sheri Paquette   Thank you for the responses!
I did check the auto bracketing as Bob had mentioned and that was the problem! Not sure how it got changed but it did!
And thanks Peter for the info. I didn't know that either. I'm really enjoying your course!

  I'm glad you found out a simple solution to what you first thought would be a major problem.
Unfortunately, the Fn Button is positioned in such a way that it can be accidentally depressed when you pick up the camera.
Then with that button depressed, you spin the Main Command Dial thinking you're just selecting a different shutter speed and you've set the Auto-Bracketing instead.

(...As you may have guessed, I did the same thing myself.)

Bob
