Central Vermont 444 at Palmer

Back in the mid-1980s, I’d often catch Central Vemont’s southward road freight arriving at Palmer, Massachusetts. This would operate overnight from St. Albans, and typically arrive in the morning.

On this occasion, 444 was lead by a colorful mix of locomotives including Grand Trunk Western GP38 5808 and a couple of GTW GP9s, a CV GP9, and a Canadian National M-420.

I must have been so enthralled by the array of motive power that I didn’t mind my exposure. My original slide is about 2/3s of a stop over exposed. Which means the photograph is too light.

Back in the day, I’d instantly reject an image of this quality as ‘unsuitable’ for projection. Although, I labeled the slide, I filed it away with my ‘3rds’, where it was protected from the light for more than 34 years.

I scanned it the other day using a Nikon Coolscan5000 digital scanner, making a multiple pass scan to extract the most amount of data possible in a 4000 dpi scan, then imported the TIF file into Adobe Lightroom for adjustment.

The actual adjustment required to correct for over exposure required just a few seconds of my time. Using the histogram as a guide, I lowered the exposure, set the black and white limits and exported as a JPG for presentation here.

Below is the unadjusted scan, followed by my exposure adjusted scan.
