When I bring in a series of photographs with very clear dramatic light changes, the keyframe wizard still only creates one keyframe.  What could be the cause of this? Do I need to let the entire exposure luminescence curve load before clicking keyframe wizard?  

thanks,
Jimmy

The auto detection of the keyframes wizard is only a suggestion and does not use a very sophisticated algorithm. Normally you will know better how many keyframes you need - just use the slider to set the right amount for your sequence.
