Amtrak Pepsi Can on Kodachrome—High Resolution Scan (and how I made it).

I have thousands of properly exposed Kodachrome slides from the 1980s and 1990s. This view of Amtrak 502 was exposed at Oakland, California 16th Street Station in August 1992.

Gradually I’ve been scanning these into my archive. I’ve experimented with several different scanners and software, using various settings and techniques.

So far, I found that I get sharpest and most colorful scans by using a Nikon Super Coolscan 5000 driven with VueScan 9×64 (version 9.5.91) software.

VueScan offers me a high degree of control, but I’ve found requires a bit of practice and experimentation to obtain the best scans.

I typically scan Kodachrome 25 slides at 4000 dpi (dots per inch) and  then output as a Tif file to obtain the greatest amount of data. For this slide I opted to make a multiple pass scan to retain a higher degree of shadow detail. (VueScan offers the multiple pass option under its ‘Input’ pull down menu).

To make the most of the scan for internet presentation, I imported the Tif file into Lightroom and lightened the shadows and balanced the highlights, before outputting as a scaled Jpg. (The original scan remains unchanged during this process).

Kodachrome slides recorded tremendous amounts of information and the original Coolscan Tif is far too large to present here.

Incidentally, a version of this photo appears on page 148 of my book Modern Diesel Power (published by Voyageur Press in 2011). The scan in the book was made by my publisher and isn’t the scan presented here.
