Re: How The West Was Won in CINERAMA with no seams!
Looks like you are right. Or has the top image been cropped on the sides? Robert Crawford was right. One still can be deceiving and is not really indicative of anything. Either way, I got the wrong interpretation from those images.
Unfortunately, I have never seen a theatrical presentation of the film, so I can't say if the blue sky in the top image is accurate to the original film. The Blue sky in the processed image looks closer to the natural color of sky, at least to me.
