Canon 20D Question

[rightfrog]

Hi,

I recently bought the Canon 20D to do timelapse photography and have pretty much figured it all out, but one thing is still killing me...

I have the camera set to manual. I set my exposure and everything, but then there's that little exposure compensation thing that seems to have a mind of its own. I can't figure out how to turn that off (the manual isn't very intuative on this topic)...

What happens it that the exposure compensation moves around from shot to shot which gives me different exposures from frame to frame causing flickering...and it angers me...

Anyone know how to disable it while in Manual mode?

Thanks,

If you're actually in manual mode, therre shouldn't be any exposure compensation. Give us some more detail if you could...what file format are you using? How are you viewing the files (on the camera's lcd or on your computer)? Can you perhaps post some images with the EXIF data included so we can see what's happening?

I have had the same issues with flicker, mainly daytime timelapse.
From my research, i have found out that when shooting jpeg, the compression of each picture is not exactly the same, causing a slight exposure change.
I dont really understand how this happens, i will write more when i gather more info.

I did notice that when i shoot closer intervals(3 seconds or quicker) that the flicker does not happen.
