Daily Post; Washington Summit‑30 years After Exposure.

Modern Technological Miracle: Post Processing.

In mid-July 1984, I heard the distinctive roar of EMD 20-cylinder engines working an eastward train on the west slope of Washngton Hill. My friends and I were positioned at the summit of the Boston & Albany route, as marked by a sign.

We often spent Sunday afternoons here. Rather than work the more conventional location on the south (west) side of the tracks, I opted to cross the mainline and feature the summit sign.

As the freight came into view, I was delighted to see that it was led by a set of Conrail’s former Erie Lackawanna SD45-2s! While these locomotives were more commonly assigned to helper duties at Cresson, Pennsylvania on the former PRR, during the Summer of 1984, all 13 of the monsters worked the Boston & Albany.

I have a number of photos of these machines, both on the B&A and PRR routes. However this image of engine 6666 never made my cut. Back lighting and hazy afternoon light had resulted in a difficult negative. My preferred processing techniques of the period didn’t aid the end result, and at the time I dismissed the photograph as ‘unsuitable’.

The other day I rediscovered this unprinted view and decided to make a project of it. Now, 30 years later, I felt it was worth the effort. I scanned the negative and after about 30 minutes of manipulation using Adobe Photoshop, I produced a satisfactory image.

I made a variety of small and subtle changes by locally adjusting contrast and sharpness. These adjustments would have been difficult and time consuming to implement using conventional printing techniques, but are relatively painless to make digitally. I’m really pretty happy with the end result.

DAILY POST: Contrast on the Bayshore Cutoff.

February 4, 2014 brian solomon 1 Comment

A San Francisco Slide Challenge.

I’ve long been intrigued by the short section of the former Southern Pacific Bayshore Cutoff at the old Potrero Wye, where the railroad runs beneath I-280.

This location offers a graphic contrast; the immensity of the highway shadowing the railroad both literally and metaphorically.

The location also poses a photographic challenge. During high light, the tracks are completely within shadow, so I’ve found the best time to photograph is early in the morning or late in the day, when sunlight is below the bridge.

Yet, low sun also poses a problem, as calculating exposure is neither intuitive nor can a camera meter be relied upon. The overwhelming highway structure will tend to result in overexposure as a camera meter tries to compensate for the darkness, yet the side of the train reflects the full brightness of the sun (which to further complicate matters, may be less than sun at midday).

I made this photograph of an inbound Cal-Train ‘Baby Bullet’ in April 2008, using my Canon EOS 3 with a 50mm lens on Fujichrome slide film. I used my Minolta Mark IV handheld meter in reflective mode to sample the exposure on the side of a gray highway support column, and preset my camera accordingly. (I didn’t make note of the exposure, but it was about f5.6 1/500^th of second.)

The resulting color slide looks just about perfect, but my exposure/contrast problem was repeated when I went to scan the image.

My first scan of the slide result in this unacceptably dark and contrasty image. Specifically there was compression of the exposure curve that resulted in highlights that are too dark and a serious loss of shadow detail. I'd made this scan using my Epson V600 with the auto exposure 'on'. Obviously to get a better scan, I'd need to take exposure matters into my own hands. — My first scan of the slide resulted in this unacceptably dark and contrasty image. Specifically there was compression of the exposure curve that resulted in highlights that are too dark and a serious loss of shadow detail. I’d made this scan using my Epson V600 with the auto exposure feature ‘on’. Obviously to get a better scan, I’d need to take exposure matters into my own hands.

Here, I found the scanner software’s auto exposure had the reverse problem of my in-camera meter and tended to underexpose the scan. The result was not only too dark, but unacceptably contrasty.

I switched off the auto exposure, and instead used the software’s exposure histogram to set exposure manually as to better balance the highlight and shadow areas. Using this setting, I made a another scan. Afterwards, I fine-tuned the improved scan using Photoshop to make for a more pleasing image by adjusting both contrast and color balance.

This is my second scan. To capture the full dynamic range of the slide, I've broadened my exposure curve manually. Notice that there is considerably more detail in the shadow areas than in the original scan. I've allowed the over all image to appear relatively flat in order to obtain as much detail as possible between the extremes of highlight to shadows. This is an intermediate stage, as the image still doesn't please me. — This is my second scan. To capture the full dynamic range of the slide, I’ve broadened my exposure curve manually.

I still wasn’t satisfied. The image was neither as I remember it, nor as it appears in the slide. So went back to the second scan and made a new set of modifications, see below.

Here is the fourth version of the image, and in my opinion the version that most accurate interprets the scene as I saw it. I've further manipulated the exposure curve to improve the highlight and shadow contrast while retaining detail in both areas. I was also slightly less heavy handed in my color adjustment because I felt that a warmer tone suited the scene. — Here is the fourth version of the image, and in my opinion the version that most accurately interprets the scene as I saw it.

This image is an exception; most of the time I’m satisfied with my first scan. Incidentally, the pictures reproduced here are scaled Jpgs from very large Tiff scans. The file size of the Jpgs is just a fraction of the original scan size, which is adequate for small-size internet viewing.

DAILY POST: Amtrak Heritage P40 at West Warren, Massachusetts!

February 2, 2014 brian solomon 4 Comments

Light! Camera! Action!

Here we have an instance where everything came together nicely.

Amtrak heritage locomotive — Amtrak 449 at West Warren, Massachusetts, 2:03pm January 24, 2014. Canon EOS 7D fitted with a 40mm pancake lens exposed at ISO 200 f5.6 1/1000th of a second. Camera RAW file converted to a Jpeg in Adobe Photoshop.

On Friday January 24, 2014, I’d got word that Amtrak’s heritage locomotive number 822 was working the westward Lake Shore Limited, train 449

This was the second time in a ten-day span that I’d be alerted to a heritage locomotive on this run. As noted in my January 18, 2014 post, Amtrak’s Lake Shore Limited, the weather wasn’t cooperative on my previous attempt at catching an Amtrak heritage locomotive.

By contrast on January 24th it was clear but very cold. I opted to make the photo at West Warren, where it’s nice and open and there’s a distinctive landscape.

Normally, Amtrak 449 passes East Brookfield at 1:30pm, and Palmer about 1:50pm. West Warren is roughly halfway between them, so I aimed to be there no later than 1:35pm

As it happened, 449 was delayed on Charlton Hill and passed more than 15 minutes later than I’d anticipated. Other than resulting in my nose getting a bit cold, this delay produced little effect on the photograph.

I opted for a traditional angle because I wanted to feature the locomotive as the primary subject this scenic setting. I picked a spot on the road bridge over the Quaboag River where I could make a view that included the old mills and waterfall, as well as a side view as the train got closer.

Working with my Canon EOS 7D fitted with a 40mm pancake lens, I set the motor drive to its fastest setting, and exposed three bursts of images as the train rolled east on CSXT’s former Boston & Albany mainline.

Since the camera’s buffer will quickly become saturated when making multiple photos in rapid succession, I was careful to wait until the train was nearly where I wanted it in each of the three sets.

DAILY POST: Kodachrome Afternoon at West Springfield, February 1986

January 26, 2014 brian solomon 3 Comments

Making and old Slide Even Better.

Here we have a typically New England scene; a fresh blanket of snow has fallen and the sky has cleared to a clear blue dome. Perfect light right?

Not exactly. The great contrast between the brilliant bright snow and the shadow areas makes for a difficult exposure. Complicating matters was Conrail’s rich blue paint.

While I was fortunate to catch Conrail’s TV9 leaving West Springfield Yard, I faced an exposure conundrum. If I exposed for the train, I risked grossly over exposing the snow, furthermore if I simply set the camera based on the snow on the ground, I’d end up with a pretty dark slide.

In the end I compromised, and stopped down enough to retain detail in the snow, while leaving the rest of the scene reasonably exposed.

However, 28 years later I’m still not satisfied with the slide.

There are three problems. I was concentrating on the exposure and the moving train (while trying to manipulate two cameras simultaneously) and I missed the level by about two degrees. Secondly, the Kodachrome film had a decidedly red bias, which resulted in pinkish snow (hardly what my eye saw that day).

I was easily able to correct these flaws after scanning the slide. I imported it into Photoshop and made three changes.

1) I cropped and rotated the image to correct for level.

2) Using the red-cyan color balance sliders, I shifted the highlights and mid-tone areas to toward cyan to minimize the excessive red in the scene. (cyan is the color opposite of red)

3) I made a localized contrast adjustment on the locomotives by outlining the area I wanted to change and then making a slight change using the curves feature.

I’ve illustrated the original unmodified scan two intermediate steps and the final image.

Here I've corrected the level; and using the color balance sliders I've shifted the color balance in the highlight and mid-tone areas to eliminate the pink-cast. — Here I’ve corrected the level; and using the color balance sliders I’ve shifted the color balance in the highlight and mid-tone areas to eliminate the pink-cast.

The last step requires a subtle localized contrast adjustment. I selected the area to be adjusted and made a very minor change to the contrast and color balance. For this example I've grossly exaggerated the area selected strictly to illustrate where I've made the changes. — The last step requires a subtle localized contrast adjustment. I selected the area to be adjusted and made a very minor change to the contrast and color balance. For this example I’ve grossly exaggerated the selected-area strictly to illustrate where I’ve made the changes. Obviously the extreme contrast change looks absurd when viewed out of context.

Here's the final image. One last change require the use of the burning tool; I made a few light passes around the seem between the area of localized contrast change to minimize the effect. My feeling is that if you can quickly perceive the adjustment, then the effect is too extreme. — Here’s the final image.

Sunrise at East Deerfield Yard, October 18, 2013

October 22, 2013 brian solomon Leave a comment

Applying an Old Technique with Today’s Technology.

The other day I arrived at Pan Am Southern’s Boston & Maine East Deerfield Yard shortly after sunrise. Although not a wheel was turning, there was some nice light and I made a selection of images.

My challenge was in the great contrast between the ground and sky. With my Lumix LX3, I found that if I exposed for the track area, the dramatic sky was washed out (too light), and if I exposed for the sky the tracks area was nearly opaque.

Railway yard. — East Deerfield Yard, Massachusetts at Sunrise. Unmodified ‘in camera Jpg’. Lumix LX3 photo exposed using the ‘V’ (for Vivid) setting.

With black & white film, I would have compensated my exposure and film development to maximize the information on the negative, then dodged and burned critical areas on the easel in the dark room to produce a nicely balanced print. I’d done this thousands of times and had my system down to fine art.

I applied this same basic philosophy the other morning at East Deerfield. I made several exposures from different angles. In one of these I slightly overexposed the sky to retain some detail in the track area.

The in-camera Jpg from this still appears both too dark and too contrasty (from my perspective having witnessed the scene). Rather than be content with this inadequate photograph, I took a copy of RAW file that I exposed simultaneously (one the benefits of the LX3 is it allows both a Jpg and a RAW to be exposed at the same time) and imported it into Photoshop. (I always work from a copy and I NEVER manipulate or alter the original file).

Under the ‘Image’ menu, I selected ‘Adjustments’ and then ‘Curves’; I then adjusted the curve to produce a more balanced over all exposure. This is possible because the RAW file has more information (detail) in it than is visually apparent.

While this improved the image, I still wasn’t satisfied. So I selected the ‘Dodge and Burn tool’ (which appears in the tool bar as a angled gray lollipop). Using the ‘Dodge’ function, I very slightly and selectively lightened track areas and foliage that I felt appeared too dark.

Then I used the ‘Burn’ function to selectively adjust the sky areas. If I’ve done this successfully, the scene should appear very close to the way I saw it. Similar techniques can be used to make for surreal and unnatural spectacular landscapes. While I may do that later, that’s not my intent today.

East Deerfield, Massachusetts. — The same image as above, but from a modified RAW file using Photoshop to adjust contrast (both across the entire image and locally). Lumix LX3 photograph.

While modern tools, like those of the traditional darkroom, allow for improvement over in-camera images, the effort does take time. I estimate I spent 10-15 minutes adjusting this photograph.

Because this adds time to the work on the photograph, I don’t want to have to do this any more often than necessary. Most of my photographs are ready to go ‘in-camera’ (as it were).

Conrail, Middlefield Massachusetts, October 3, 1993.

May 10, 2013 brian solomon 4 Comments

Salvaging A Dark Slide From the Archives.

Sunday, October 3, 1993 was a fine autumn day. I was visiting New England, after some eight months in California, and met my friend Bob Buck along the Boston & Albany route at Palmer. He was reading his Sunday paper, and looked up, “Are you interested in going to the West End?”

Silly, question! Bob had introduced me to the old B&A West End a dozen years earlier, and as the living expert on the B&W, there was no better guide for my favorite line. So off we went in Bob’s Ford van, via the Mass-Pike to Westfield and then up the mountain. The railroad wasn’t especially busy that day, but we saw a few trains.

Our first stop was Chester. Then we went up to Middlefield, a location that Bob had found way back in 1946. On that day he’d watched B&A’s mighty A1 class Berkshires on freight. Those days were long gone, but Bob spoke of them as if they were yesterday! We walked west to the famed Twin Ledges where Bob had made many great photos of steam power, then as the daylight faded returned to the old Middlefield Station location (the building was demolished decades earlier).

Middlefield is a peaceful bucolic place and an idyllic setting to watch and photograph trains. Toward the end of sunlight, we heard a eastward train descending. Since I’d made dozens of photographs at this location over the years, I thought to try something a little different, and so I framed the train with these leaves around it.

Shafts of rich afternoon sun illuminated the golden foliage, casting a bit of golden glint light on the rail. It was a stunning scene. But, just as the Conrail train crawled into view, clouds obscured the sun. Poor show.

Not withstanding, I exposed this frame of Kodachrome 25 with my Nikon F3T, making a last second exposure compensation; f2.8 1/125. K25 was a forgiving film, but this wasn’t enough exposure, and the slide came back from Kodak looking dark and uninviting. Not much use in a slide show. I put it away and haven’t looked at it since. Until today that is.

Yesterday’s photographic folly has become today’s project. I can’t exactly catch a set of Conrail C30-7As working the Boston & Albany route anymore, and this image retains strong composition despite its flaws. What was merely a dark slide in 1993, can now be adjusted with Adobe Photoshop.

Below I’ve displayed four images. The original ‘Dark’ image. Plus three altered scans. Option 1 involves little more than a quick adjustment with the ‘curves’ feature to compensate for under exposure, while Options 2 and 3 involved varying degrees of manipulation to compensate for exposure, color balance and apparent sharpness. I’ve used various masking, layering and other types of selective adjustment. Which is the best image? You decide. I make no apologies, It’s an old dark slide, there’s no right or wrong.

This is an unmodified scan of the original Kodachrome slide. By my estimation its about 2 stops under exposed. — This is an unmodified scan of the original Kodachrome slide. By my estimation it’s about 2 stops under exposed.

Modification option 1, the quick fix. I simply adjusted the 'curves' feature in Adobe Photoshop to compensate for underexposure.

Modification option 2, this is a heavily modified scan, using layers and selective tools to make localized as well as global adjustments.

Modification option 3, this is the most modified of the three scans. Again, I've used layers and selective tools to make localized and global adjustments, paying special attention to the sides of the locomotive, highlight and shadow areas. I could have toiled over this for another half hour, but would it make that much difference. Pity the sun hadn't stayed out, but so be it. No one said the Photoshop fix was easy. — Modification option 3, this is the most modified of the three scans.

Boston & Maine Slug Set at Rices, near Charlemont, Massachusetts; June 26, 1986.

April 14, 2013 brian solomon 1 Comment

A Kodachrome View of Boston & Maine’s West End

Yesterday, April 13, 2013, Pan Am Railways hosted a passenger excursion over the historic Boston & Maine route from Boston to Mechanicville. My father, Richard Jay Solomon, was among the passengers, and he sent me regular updates on his progress. This inspired me to revisit images such as this one.

Boston & Maine railroad along the Deerfield River. — Exposed on Kodachrome using a Leica 3A fitted with a 65mm Elmar and Visoflex.

Scouring the archives, I found this Kodachrome slide from the 1980s. It shows Guilford’s Boston & Maine mainline at Rices, near Charlemont, Massachusetts at 11:05 am on June 26, 1986. A westward freight led by B&M’s lone GP40-2 slug set (on left) is holding at the signals for an eastward train coming from Mechanicville, New York.

This image was never among my best photographs. At the time, I was using my old Leica 3A fitted with a 65mm Elmar using a Visoflex reflex arrangement. To gauge exposure, I used an antique hand-held General Electric photo cell. The camera arrangement allowed for a sharp image but was awkward to use. More to the point, the meter wasn’t very accurate and my sense for exposure wasn’t highly tuned. As a result, this slide was overexposed, as were most of my efforts from the day.

Thankfully, my choice of film at the time was Kodachrome 64, which was relatively tolerant of inaccurate exposure. So while, this slide appears too bright when projected on screen, the emulsion retained sufficient detail to be recovered digitally. I scanned the slide using my Epson V600 scanner, then corrected for my flawed exposure with Adobe Photoshop by manipulating the ‘Curves’ function. The end result isn’t objectionable.

Kodachrome with Montana’s Big Sky

February 7, 2013 brian solomon Leave a comment

Big Sky on the old Great Northern — Changing skies on Montana’s Marias Pass. On July 6, 1994, an eastward intermodal train approaches Grizzly on the former Great Northern mainline. I exposed this image less than a week after announcement of the Burlington Northern-Santa Fe merger. Nikon F3T with f1.8 105mm lens; exposed on Kodachrome 25.

Kodachrome 25 film exposed with a Nikon F3T with 35mm PC lens.

Look up, take in the heavens and transform a railway scene in to a cosmic image. That’s a theory anyway. During my 1994 visit to Montana, I was awed by the amazing skies for which the state is famous. Big sky and wide-open vistas can make for impressive railway images, yet getting the balance between right between atmosphere and railway is no easy chore. Here, I’m offering two of my most successful attempts. Both were exposed on Kodachrome 25 using my Nikon F3T. The peculiarities of Kodachrome’s spectral sensitivity made it a great medium for working with textural skies and dramatic lighting. Not only did Kodachrome 25 benefit from exceptional dynamic range, but also the way it translated blue light I found conducive to dramatic images featuring impressive skies.

While these slides look great when projected on a screen, and both were successfully reproduced in my 2005 book Burlington Northern Santa Fe Railway, I found they required a bit of adjustment using Adobe Photoshop to make them look good on the computer screen.

Different tools yield different results and I wonder how I might I use my Canon 7D or Lumix LX-3 in similar lighting situations.
