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<\/em> as it worked upgrade along the Truckee River on Southern Pacific\u2019s famous Donner Pass crossing.<\/p>\n\n\n\n

The other day, I scanned this slide and then imported the unmodified scan into Adobe Lightroom to make corrections.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

The roll I used was relatively fresh and required significant color adjustment to produce a near neutral bias.<\/p>\n\n\n\n

I\u2019ve included scaled versions of: the unmodified scan, the color and contrast adjusted scan, and the Lightroom work window. <\/p>\n\n\n\n

Notice that I manually moved the black point to the left, while lightening shadows and reducing overall contrast. This helps correct for the effect of midday sun in the California Sierra.<\/figcaption><\/figure>\n\n\n\n
