Strasburg Rail Road’s preserved J-Tower made for an ideal static subject to test Nikon’s Z6-III image-making with f1.4 Nikkor lens at ISO 64000.<\/p>\n\n\n\n

For point of comparison I made exposures at ISO 100 and ISO 64000.<\/p>\n\n\n\n

I then converted the ISO 64000 image to a DNG format using DxO PureRaw which denoised the image while eliminating vignetting and other lens imperfections. I’ve enlarged the tower section of each image to make comparison easier. <\/p>\n\n\n\n

My next Railroad Photography 101 Class at the Railroad Museum of Pennsylvania will be held on Saturday Dec 13, 2025 from 9 to 11am. The theme to this class will be working with holiday settings, including how to make better night train photographs.<\/p>\n\n\n\n
