The left slide (Scan-100425-0026_1.jpeg) is E100VS while Scan-20101031-0034_1.jpg is Elite Chrome 100 Extra Color. There are differences is lighting and scenery but none which could explain the difference in color palette IMHO. The scans mostly represent what the slides show, but be aware that I have no color corrected equipment.
Thanks for sharing....definitely a huge difference there. It's interesting to see things like this side by side.
