Yesterday, October 15, 2020, I made a late season foliage photo of Conway Scenic Railroad’s Mountaineer descending from Crawfords at milepost 79 near the Arethusa Falls grade crossing.
Working with my FujiFilm XT1 and 90mm prime telephoto, I set the ISO to 1000. I needed relatively high sensitivity because I was working in the shadows of the trees and mountain side and wanted a sufficiently fast shutter speed to freeze the motion of the train, while using a smaller aperture to minimize headlight bleed.
Then I imported the Fuji RAW files directly into Adobe Lightroom for processing, while making a comparison set of files by importing them first into Iridient X-Transformer which converts the files to a DNG format and then imported these into Lightroom.
As previously described on Tracking the Light, the Iridient software does a superior job of interpreting the Fuji RAW files.
