Parallel Bridges at Rupert—four stages of correction

Last week Kris and I visited Rupert, Pa. where, at one time, the Lackawanna interchanged with Reading Company.

Here, parallel railroad bridges cross Fishing Creek.

The old Reading truss bridge is long abandoned, while the former Lackawanna plate girder bridge is now used by the North Shore Railroad short line.

Working with my FujiFilm XT1, I exposed this view as a RAF (RAW) image. Below are four variations of the same file that aim to show steps toward achieving a final image.

First I converted the RAF file into DNG format using Iridient X-Transformer. Then I made some nominal corrections with Lightroom.

Out of curiousity, I then returned to the original RAF file and converted it DNG using DxO PureRaw, a program with which I’ve been experiementing recently.

Note: in this excercise I made two distinct conversions from the RAF (RAW) image to the DNG format using the two different conversion programs. I did not re-convert the already converted image.

Working with the PureRaw DNG in Lightroom, I found that this conversion gave me much greater latitude to improve detail and color in the sky. While the sky appears nearly white in the unadjusted files, using the highlights slider in Lightroom I was able to draw in considerable detail.

Overall, I found that the PureRaw-created DNG file was easier to adjust in Lightroom and allowed me to create a better end-result.

I plan to continue these experiments.

Iridient X-Transformer created DNG file, scaled without cosmetic adjustment.
Iridient X-Transformer created DNG file, scaled following adjustments to shadow-areas, highlights and color balance. Note the sky.
PureRaw created DNG file, scaled without cosmetic adjustment. This software corrected for a variety of lens defects among other transformations.
PureRaw created DNG file, scaled following significant cosmetic adjustment, including nominal cropping. Notice the differences in the sky detail compared with the other variations.

PureRaw Cotton Candy Sky

There was a cotton candy sky hanging over Strasburg.

I thought this offered an opportunity to demonstrate the advantages of exposing using RAW, then converting the file using DxO Pure Raw softwar and importing the converted file into Lightroom for adjustment.

Below are three versions of the same image exposed using my Nikon Z6 with 28-70mm lens

The first image is the in-camera Jpg (scaled without adjustment). The second is the NEF RAW file after conversion to PNG format using Pure Raw. The last is end result following adjustment in Lightroom.

In camera JPG without adjustment.
NEF file converted using PureRaw to correct for lens defects, reduce pixelization etc.
PNG file following adjustments in Lightroom to make better use of shadow and highlight detail, adjust contrast and color balance, etc.
