On our most recent visit to Palmer, Mass., in addition to architectural photos of the old Union Station building, I also made some views of Amtrak 448, the eastward Boston-section of the Lake Shore Limited rolling by the building.

I’ve made similar views over the years by day and by night. In recent years the brush along the tracks has partially obscured the view of passing trains. I opted to include the brush in the photo, rather than make a tight view that may have cropped the station, which was the primary subject.

Below are two versions from the same NEF RAW file. One is a JPG converted straight from the RAW without denoise or demosiac adjustment. The second was converted using DxO Pure Raw 4, which includes both denoise, demosiac features that removes/mitigates pixelization and diestracting artifacts as result of using the sensor at high-ISO (in this case 12,800), and also corrects for lens defects that are specific to my 24-70mm Nikkor Z-series zoom

Over the last few weeks I’ve been experimenting with a demo version of the DxO Pure Raw 4 software. This was recommended to me by Tracking the Light reader David MacKenzie. This sophisticated software requires several minutes of processing time for exach file, but cleans up many of the objectionable qualities inherant to high-ISO files, and allows for significantly superior end results.

Over the next few weeks, I plan to display a variety of results using DxO Pure Raw 4, and other processing software.
