In June 1994, I exposed this Kodachrome 25 slide using a Nikkormat FTN fitted with a Nikon AF28mm lens (focused manually) of Amtrak number 5, the westward California Zephyr as it worked upgrade along the Truckee River on Southern Pacific’s famous Donner Pass crossing.
The other day, I scanned this slide and then imported the unmodified scan into Adobe Lightroom to make corrections.
Kodachrome 25 was an amazing film with very fine grain and a tremendous exposure latitude. Among the difficulties with the Kodachrome emulsions was its cyan/red color bias. When the film was fresh it tended toward a cyan (blue-green) bias, and as it aged it shifted red.
The roll I used was relatively fresh and required significant color adjustment to produce a near neutral bias.
I’ve included scaled versions of: the unmodified scan, the color and contrast adjusted scan, and the Lightroom work window.
