Tips and Technique

Swiss Stadler at Champery.

Leave a comment

The ability to improve my interpretation of Fuji RAW files using Iridient X-Transformer made me curious to re-examine some of my Fuji photos from years gone by.

I selected a photo that I made on trip to Switzerland with photographer Denis McCabe in April 2017. This image was made at the Champery terminus of a TPC branch that extends into the Alps from Aigle. 

Here I’ve presented a comparison between the Lightroom interpreted RAW (scaled and converted to JPG for internet presentation) and the same file converted into a DNG file using Iridient X-Transformer. Since it is difficult to appreciate the improved sharpness when viewed on a small scale, I’ve enlarged a portion of each image that focuses on the LED lamps and rivets on the then new Stadler railcar.

The final image was derived from the Iridient converted DNG and involved nominal adjustments to color balance, color temperature, contrast and saturation that are aimed a making a more pleasing final photograph.

This image is derived from the same Fuji RAW file but converted into a DNG file by Iridient X Transformer before being scaled as a JPG file in Lightroom. There were no changes to color, contrast or level.
