I was taking pictures yesterday for a panorama (see this post here.) But when I put the camera on Manual mode, the Auto Exposure still changes every image. How do I turn off AE to where it will be on "0" all the time? I am trying to make each image with the exact same settings. If it helps, I have the firmware hack.

I know I could adjust the exposure in the RAW image, but the AE setting isn't printed in the EXIF data (unless I missed it).

what makes you think the auto exposure is overriding the manual settings? the exif data does show aperature, shutter speed, and iso setting .... is it the same for all the shots?

Unless I am mistaken, I believe that the Automatic Exposure feature is or can be disabled when in (M) - Full Manual Mode.

Make sure your white balance is on manual also. Sometimes the subject will fool the Auto White Balance.

Just figured out what you meant by this question. When in manual mode, if you 1/2 press the shutter, the camera will let you know that the exposure is off by highlighting something other than "0", but it doesn't change anything, it takes the photo at the settings you have choosen.

That sure is the way it works. What would be the point of being in Manual Exposure mode if it was not to have manual control of the exposure. Of cousre the camera's meter will still control the Exposure Level Indicator in the viewfinder to show over or under exposure in in this mode. That has no effect on the actual exposure though. All exposure is controlled by the photographer with the ISO, shutter speed and aperture in this mode.

Thanks guys. The indicator was throwing me off. I just assumed that if the needle was moving when I pressed it half way down, that was the setting it was going to use in the shot. Please forgive my dumbness :-)
