Saturday, I made this view of a former Reading Company caboose at Kempton, Pennsylvania on the Wanamaker, Kempton & Southern.
It was shortly before 3pm and the sun was still high in the July sky.
Using my Nikon Z6 with 24-70mm I exposed the photo in both JPG and RAW. Then in post processing using Adobe Lightroom, I adjusted the camera RAW (NEF format) so that I made full use of the camera’s dynamic range.
Notice how in the adjusted versions you can see detail inside the caboose.
My Nikon Z6 is prized for its dynamic range, in other words its ability to capture detail at the extreme end of the range from dark to light.
Today, I am posting three variations of the same image file.
This is from Sunday’s chase of Pan Am Railway’s SAPPI-3 and pictures the freight crossing Martin Stream near Hinckley, Maine.
The bucolic setting was side lit–a condition that presents a contrast challenge. I made the image using my FujiFilm XT1 with 28mm pancake lens.
Recently, and on the advice of my old pal TSH, I purchased Iridient software, which offers a different interpretation of the FujiFilm RAW files.
Below are examples of the in-camera FujiFilm JPG (using Velvia color profile), a DNG file converted from the Fuji RAW by Adobe Lightroom, and a comparison DNG file converted from RAW using the Iridient software.
All were then scaled and exported using Lightroom. I made identical color and contrast corrections to the two DNG files. (My interpretation, not Fuji’s)
My intent is to compare the Iridient processing with Adobe’s. The Camera JPG is a third reference.
Since this is one of my first experiments with the Iridient software, I cannot claim to be a master of working with it.
Friday morning, 6 September 2019, I took position at the far end of Dublin Connolly Station platform 4 to photograph RPSI’s Empty Cravens arriving from the Inchicore Work in preparation for boarding and departure of the annual Steam Dreams excursion. (More on that tomorrow!).
I wanted to make both long telephoto and wide angle views of the train. To accomplish this I could use my FujiFilm XT1 with a telephoto and then switch to my Lumix LX7 as the train approached.
However, for the sake of convenience instead I opted to work exclusively with the XT1 for this sequence, and fitted the camera with a 18-135mm zoom lens.
There’s no one ‘right’ way to execute an image (or images) but different equipment choices will produce varied results.
One reason for my using the XT1 for the whole sequence was a function of the lighting conditions. My Panasonic Lumix LX7 is an excellent camera in many respects. However, I’ve found that it has a slightly narrower dynamic range, probably owing to smaller file size.
In many situations this subtle difference doesn’t matter, but with Friday’s lighting, I wanted to be able to pull in sky detail in post processing, and from past experience the XT1 RAW files leave more to work with than those from the LX7.
Here’s a lighting challenge: A freight train crossing a big bridge against an overcast sky.
Expose for the train and the sky gets washed out (loss of detail). Expose for the sky and the train is too dark.
So what do you do?
I expose for the sky and then adjust the file in post processing.
Why? Because it is easy enough to lighten slightly underexposed areas, but once highlight detail is lost through over exposure it cannot be recovered.
To balance the exposure in post processing, I lightened the shadow areas globally. This took all of about 30 seconds to accomplish in Lightroom. I also made minor adjustments to overall color balance and saturation. Afterwards, I played with the file to make some outlandish versions for point of comparison.
Of the four, the second from the top is the only image I’d normally present. The bottom of the four is intended to be a little absurd.
