Normally without any filters applied both panes must be identical.

You talk about pictures, I do not understand.
I open a mp4-file with virtualdub and get it in two windows.
Comparing the videos in window 1 and 2 shows the same video as long as no filter is applied.
When I apply AutoLevel v1.2 filter I can see that my video in window 2 changes. I my case the window 2 then shows better quality, fresher and better colours.
What effect can you see applying the AutoLevel v1.2 filter.
