I need to have a mystery solved, so please, put on the combined OM thinking cap
and generate some theories.
It seems that I am having exposure problems and can't really figure out why.
Look at this first image:

It consists of three exposures taken in order from right to left. I know that
some of you can't see it well after resizing. It was ok on my monitor at
home...
I stitched the three images in PS. If you see the original file, there is a
little difference where the first and the second image were blended, and it is
more than obvious where the second and third image were blended (the right
third of the cloud).
Why my images get progressively darker? This was taken as one image and after
the stitch, the previous one shoudav looked like it:

Both images were taken with the A200 and it was explained to me that the cause
is the white ballance, which was on Auto (actually I think this is the very
first image I took with this camera). I did believe this, but not anymore.
Last night, I scanned some film. This is a composite of pictures taken with my
OM1 on Fuji Superia 400. It was the last picture taken before I left
Connecticut almost two years ago.
I did not stitch the images, so the amount of overlap can be seen. The first
image was the one on the left this time. Notice the pattern? The first image
is well exposed, and the second darker. Same as before, but this time the
difference is that in reality, I was going towards the lightsource, i.e. the
right portion should have gotten progressively lighter as opposed to the first
picture, where I started with the portion where the sun is and left the darkest
portion of the sky for last.
All I did was to turn the camera slightly to left or right, that's all. And in
the case of the OM, I don't have WB. And yes, in both cases I kept constant
aperture and shutter speed. As noted the only auto function was the WB with
the A200.
Anyone has scientific explanation?
Thanks
Boris
P.S. Here is the OM image:
