Here’s an archived digital view I made in the summer of 2011 at Smithton, Pennsylvania along CSX’s former Baltimore & Ohio mainline.
Bad luck, just as this eastward freight came into view, a fair weather cloud muted the afternoon sun. I made a sequence of photos with my Canon EOS 7D.
Working with Lightroom, I re-worked the image starting with the camera RAW file. Unlike the camera Jpg which is compressed, the RAW file contains greater amounts of information than maybe immediately evident.
By making nominal adjustments in post processing, I was able to create a more pleasing photograph. I worked on the sky, locally bringing in highlight details in the clouds by moving the highlight slider control to the left, which scales back the relative brightness of the highlight areas.
On a global level (for the whole file), I brightened shadows, warmed the color balance, increased saturation and adjusted contrast.
Lastly, I focused on the train and made very slight (subtle) adjustments to the exposure by lightening and changing contrast.
For comparison, I’ve included both the unaltered in-camera JPG and two versions of the altered camera RAW file.
Here’s something different. I had my FujiFilm X-T1 set up to record monochrome with a digitally applied red filter to alter the tonality. Working with a Zeiss 12mm lens, I made this view at Arlington, Massachusetts of two MBTA buses passing on Massachusetts Avenue.
My Lumix LX7 has an ‘high-dynamic range’ feature. Otherwise known by its initials ‘HDR’, high-dynamic range is a technique for digital imaging that allows greater detail in highlights and shadows by combining several images of the same subject that were exposed at different values.
The LX7 includes the HDR setting as one of the options in ‘scene mode’ (SCN on the selection dial). This rapidly exposes a sequence of images and combines them in-camera to produce a single HDR JPG. Obviously you need to hold still when you make the photo.
Also it helps to photograph a static scene or the result my get a bit weird.
In this instance, I photographed some flowers on the platform of NI Railway’s station at Whitehead, Co. Antrim (Northern Ireland).
There are other ways of accomplishing a similar result.
So I decided to compare the HDR with some manipulated versions of a camera RAW file that I exposed of the same scene. With the RAW images, I’d adjusted the file with Lightroom post processing software, selectively altering contrast, gamma, and colour saturation and colour temperature to make for a more pleasing photograph.
Specifically I applied a digital graduated neutral density filter, while making global changes to highlights and saturation.
The output of the RAW is also as a JPG, which I scaled for presentation here.
I made two versions of the RAW interpretation.
In both sets of images I’ve intentionally focused on the flowers and not the NIR train.
June can be a challenging time to make photographs. There can be wonderful rich sun for couple of hours in the morning, and again in the evening, while during the day high-light presents difficulties with contrast and deep shadows. (Topics for future posts)
Last week, Rich Reed, Paul Goewey, Felix Legere and I arrived at Ayer, Massachusetts in good morning light.
MBTA and Pan Am Railways kept us busy for a little while. And I made these images using my FujiFilm X-T1.
I gauge my digital exposure using the camera’s histogram (a graph displayed in-camera that shows pixel distribution), and as a result I aim to capture the maximum amount of data by balancing the highlight and shadow areas.
If need be I can then adjust the exposure and contrast in post processing to make for the most visually appealing image without sacrificing the amount data captured
I’ve listed my exposures below each photo to provide a frame of reference.
