LUAS Tram Crash on Benburb, Street Dublin September 10, 2012

On the morning of September 10, 2012, LUAS tram 4010 proceeding westward on Benburb Street toward Heuston Station in Dublin collided with a bin lorry (garbage truck) near the Croppies Park. This accident occurred on my virtual door step, so I reluctantly availed myself of the opportunity to make photos. I say reluctantly because I don’t relish railway accidents and I prefer to portray railways in a positive light. However, the proximity of the crash, and the fact I just completed my first LUAS video the previous day (September 9, 2012) encouraged me to make the ten minute walk to the crash site.

LUAS Crash on Benburb Street Dublin September 10 2012

When in Dublin, I routinely walk the route of the LUAS, and have passed this spot hundreds of times in the eight years since LUAS Red Line operations commenced. In fact, the Irish Railway Record Society Journal recently published a photo I made of LUAS at this location during the visit of Queen Elizabeth II in May 2011.

I regularly ride the trams as well. Normally LUAS is a pleasant, safe, and convenient means to travel into Dublin, which is why I chose to feature LUAS in my video: A Tram Called LUAS. http://www.youtube.com/watch?v=pn7HWp-KbAg&sns=em

These photos demonstrate the crash worthiness of the LUAS’ Citadis trams. Although the front was smashed, glass broken, and tram derailed, considering the impact, the vehicle survived in relatively good shape and appears to have protected people within as best as is possible in such circumstances.

Sperry Train at Islandbridge Junction on August 30, 2012

Irish Rail’s Sperry rail inspection train at Islandbridge Junction, Dublin August 30, 2012.

Camera: Canon 7D fitted with an EF 28-135mm zoom.

Every so often everything comes together nicely. Yesterday (August 29, 2012), I learned that Irish Rail would be running its Sperry inspection train up to Dublin for stabling at the sidings near Heuston Station. This suits me well, as I’m staying just a short walk from Islandbridge Junction, immediately west of Heuston. While I caught the train yesterday afternoon, the conditions were less than ideal, although typically Irish; it was heavily clouded and lashing rain. I racked up the ISO to 800 on my Canon 7D digital camera and popped off a few frames, which I was happy to get. In 14 years of photographing Irish railways it was the first time I caught the Sperry train on camera.

What’s a ‘Sperry train?’ In the early part of the 20th century, a hidden rail fracture caused a serious derailment on the Lehigh Valley Railroad in New York. This tragic incident inspired prolific inventor Elmer Sperry to devise a system of inspecting rails. This consisted of a magnetic induction profile. For many years self-propelled black and yellow ‘Sperry Cars’ have been seen making the rounds on American railways. In more recent years, Sperry Rail devised a testing system using ultrasonic equipment to reveal rail fractures. Today, Sperry provides rail-defect detection services in many countries. On today’s train, Sperry’s detection equipment is in the yellow container riding on a flat wagon immediately behind the locomotive. The yellow tank wagons are to assist with braking.

A perfect sunny day greeted me this morning. I’d heard the train was due to depart the old Guinness sidings at Heuston about 9 am, so I was in place at that time. For this exercise I used my Canon 7D fitted with a EF 28-135mm lens. This arrangement gives me great flexibility, produces high quality images, and allows me to post images very quickly after exposing them. Another benefit is the digital medium allows me to make test frames that I can analyze on site to check for proper exposure, adequate focus, as well as framing and etc. For this image, the famed Wellington Testimonial (located at the east end of Dublin’s Phoenix Park) is featured. I’ve made many photos here before, but sometimes with film I’ve inadvertently cropped the top of monument while focusing on a moving train. I tried to avoid this mistake today, and with digital I could check right away, and not wait days or weeks to find out. With the camera set manually (in ‘M’ mode) I made several exposures bracketing my crop and exposure. This one was made at f6.3 1/500th of second at ISO 200; lens set to about 35mm. I made two files in camera; a large Jpg and a RAW. I made no adjustments to this image, other than scaling the large Jpg to 1024 pixels on the long side and adding my name and copyright information.

I feel I’ve had a productive morning so far! Later, I also caught one of Irish Rail’s IWT Liners, an intermodal container train that runs from Dublin Port to Ballina, County Mayo. Today, this was led by one of Irish Rail’s 201-class General Motors diesels wearing the Enterprise livery. While not unheard of, it is a good catch to see one these in freight service.

Installment 4: Lumix LX-3—part 2: Existing Light Digital Night Shots



Technique: Use a tripod and select a slow ISO; then after making a test shot, adjust exposure to ‘overexpose’ by about one stop, while using the self timer to actuate the shutter to avoid camera shake.

 

On the left an ÖBB steel train led by Siemens Taurus electrics has paused at Schwarzach-St. Veit, Austria . This photo was exposed using a Panasonic Lumix LX-3; ISO 80, lens set at f2.2 with a timed exposure estimated at one second with the camera in ‘M’ (manual exposure) mode and fitted to a portable miniature Gitzo tripod.

As described in Installment 3, the Lumix LX-3 is a compact lightweight digital rangefinder camera that features excellent optics (Leica Vario-Summicron f2.0-2.8/5.1-12.8 [mm] ASPH) and the ability to set functions manually. I’ve found this is a great tool for making urban night photos, and I’ve developed a successful technique well-suited to nocturnal railway images. I made this image with my LX-3 on January 11, 2012, at Schwarzach-St. Veit, Austria, which features double-headed Siemens Taurus electrics on a steel train.

Schwarzach-St. Veit offers a well-lit moderate-size station near the junction of two routes, one of which is the OBB (Österreichische Bundesbahnen/Austrian Federal Railways) main-line over the famous Tauern Pass through the Alps to Villach (with international connections beyond to Italy and Slovenia). Some Irish friends and I were on a week-long visit to Austria. On this evening, after dinner at a nearby hotel, we spent a little while at this station watching trains and making casual night photos. This OBB steel train had come in from the north and was awaiting a path over the Tauern, and so had paused for several minutes, which provided ample time to make some time-exposures (long exposures). Rather than go through all the effort to set up a large tripod, instead I opted for a relatively compact ‘pocket’ tripod with ball head (to adjust the angle of the camera), which I positioned on a snow bank piled at the center of the platform. Instead of using one of the LX-3’s many automatic modes, I opted to set ISO, shutter speed and aperture manually, which is easily accomplished using the ‘Q-menu’ toggle switch at the back of the camera to step through the appropriate selection menus. (Other cameras that have the ability to make manual settings will have similar means of making adjustments — consult your camera manual or guru for details.)

When making night photos, the tricky part is obtaining a satisfactory exposure while keeping stray light away from the lens. For night photography, ‘faster’ isn’t necessarily better and the first thing I did was select the slowest ISO. The slowest ISO results in less noise, offers better exposure latitude (range of exposure captured from the highlights to shadows), while offering a sharper and more saturated image. Through experience, I’ve found that the LX-3 produced its highest image quality at ISO 80, and above ISO 200 its images tend to toward the unacceptably noisy (‘grainy’ or pixilated to the eye). Since my subject is static and the camera was secured on a tripod, there’s little advantage in selecting a Higher (faster) ISO. Its true that higher ISO allows for faster shutter speeds, but in this case the difference of a stop or two would be effectively irrelevant; since the light was so low, my exposures would be relatively long anyway.

To calculate the appropriate exposure, I’ll make and analyze a test image. Here, my process may seem counterintuitive and it requires me to override the camera’s programming. In a nocturnal situation, where the sky is completely dark and there are a variety of hotspots caused by electric lamps (and in this case, acerbated by bright piles of snow), I’ve found that the LX-3’s automatic metering modes tend to seriously underexpose the image (in other words, it fails to allow sufficient light to reach the sensor). This is a result of the metering biased for daylight situations which has tendency weigh the effects of bright lamps too heavily and thus overly shorten the exposure time for a nocturnal setting. Strictly relying on either the camera meter or the basic automatic settings is an underexposed digital image. (Lumix offers some automated programmed settings to serve these situations, but I prefer to do this manually).

Another problem is the camera display image. In extreme circumstances, such as night photography, the jpeg displayed on the camera screen is a ineffective tool for correctly gauging exposure. Not only is this jpeg compressed and optimized for computer-screen viewing, but on-camera it is presented much lighter than the data in the actual file and so doesn’t provide an accurate assessment of the scene. So, what looks great on the back of the camera may in fact be way too dark in the file.

To overcome these difficulties, I make a test exposure with the camera, then carefully observe the histogram to make manual corrections that increase the exposure. In this nocturnal circumstance the majority of the histogram exposure graph may be too far to the left (indicating overall under exposure). Since I want to retain some highlight detail, I’ll make a second exposure, usually between ½ and a full stop over exposed (that is, I make the exposure lighter than that recommended by camera-meter, usually by increasing the amount of time the shutter is open, say from ¼ second to ½ second; or by using the exposure compensation feature, see below), and then gauge the histogram so that there’s a hint of highlight hitting the far right, but with the majority of the image-data filling the central portion of the graph (rather than too far to the left, as in the first exposure).

In a rushed situation, I might skip the test exposure and histogram analysis, and just increase the exposure by 2/3ds to a full stop. This can also be accomplished by simply adding in ‘+2/3’ or ‘1’ on the exposure compensation menu at the left-hand side of the screen (with the LX-3: using the ‘Q-menu’ toggle, go left until the ‘+/-’ is highlighted yellow on the screen, then with the same toggle, move up two clicks for ‘+2/3’, or three clicks for ‘+1’). Then you can use the camera in either aperture priority mode (‘A’ on the top dial) or shutter priority mode (‘S’ on the top dial). This is a great compromise, if you don’t feel confident reading the histogram. If possible, make several exposures, perhaps increasing them in 1/3 stop increments.

Examining the test exposures, I also watch carefully for flare caused by stray light hitting the front element of the lens. Flare greatly reduces shadow detail and may cause unpleasant or unnatural patterns in the image. While Hollywood productions in the 1970s ‘discovered’ the use of flare as a dramatic technique, and I occasionally use this myself for effect, generally speaking it is best avoided, especially in situations such as that at Schwarzach-St. Veit. If I cannot place the camera in a natural shadow (such as that presented by a mast, canopy, or other infrastructure), I’ll carefully shade the lens with my handheld notebook (or anything else that I have handy). It’s important to insure the notebook doesn’t crop the frame.

One last point, to avoid shaking the camera, I set the self timer for 2 seconds, and then gently stand back and remain still while the camera exposes the frame.

In this particular case I’d been making photos on the platform for about half and hour, and prior to the steel train’s arrival I’d already made a variety of images that helped establish my base exposure. The photo displayed here was exposed at ISO 80, at f2.2 for 1 second. I used the camera’s pattern metering to base the general exposure, then gave it an extra stop. (If I’d followed the camera meter recommendation, I’d have exposed the image for ½ second instead of a full second.)

 

Installment 3: Lumix LX-3—part 1 An Everywhere Camera

On March 30, 2012, a northward CSX auto rack train passes beneath the Bear Mountain Bridge near Fort Montgomery, New York, on its way up the Hudson River. This afternoon image was exposed with my electronic Lumix LX-3. This is the in-camera jpeg, made with the ‘vivid’ color profile with the camera set in the ‘S’ (shutter priority) mode using pattern metering. It was exposed at 1/640 of a second at f 5.0.

 Technique: Bring This Camera Everywhere!

I’m a big proponent of always carrying a camera. And as I’ve written elsewhere, ‘If you don’t have a camera, you can’t make a photo.’ As soon as you let this guideline slip, a unique visual opportunity will occur and you won’t be able to capture it. A caveat is: always carry a good camera (why lessen the magic of a unique event with a poor quality photo?). My father had given me an antique Leica IIIa for my tenth birthday and I carried it everywhere and made photos of everything. When I was in school I was ‘the kid with the camera.’ While many of those photos aren’t very good, the point is that I was always ready —constantly going through the motions of making photos taught me how to work under numerous lighting situations. I never relegated my photography to ‘perfect sunny days.’

Over the years my philosophy has resulted in towing around various and different amounts of equipment. Constantly carrying a film-based SLR with a full set of lenses really was pretty awkward, not to mention the big bag of film! It’s one thing to have a camera, it’s another to try to anticipate every possible situation all the time. Beginning in 2001, my ‘everywhere camera’ was a Contax G2 range finder, which had its benefits, but was comparatively heavy, and while it came with interchangeable lenses, these tended to fill my pockets.

In summer of 2009, my digital guru Eric Rosenthal lent me a Panasonic DMC LX-3; I was immediately convinced of its merits and bought one. Since then I’ve made great use of it, and I feel it is as near as perfect an ‘everywhere camera’ as I’ve ever owned. The LX-3 has a variety of kin, including the newer LX-5, as well as the almost identical Leica D-Lux3/4/5 models, with newer models recently introduced. I’ve only used the LX-3, and I’m not intending to compare my camera with the gamut of similar models or its competitors available to photographers today. Rather, I describe its pros and cons, and how this tool has benefited my photography.

The LX-3 offers several key qualities that have allowed me to make numerous excellent photographs: it’s compact, versatile, flexible, fast, durable, and offers exceptionally high quality images for its relatively small size. I can bring it just about everywhere (within reason), and with it I have a dependable tool to make photos. Three of my principle objections to many small. ‘snapshot-style’ cameras are their low-quality optics, an inability to operate the camera manually, and an unavoidable delay from the time the shutter-button is pressed to the time the shutter opens. With the LX-3, not only I can get around all of these problems, but I get performance that rivals that of much larger camera systems.

The LX-3 is equipped with a great lens — a Leica Vario-Summicron f2.0-2.8/5.1-12.8 [mm] ASPH, which is extremely sharp, fast, and offers a nice color palate. While the LX-3 has a variety of modes, it has manual capabilities that allow me to set shutter speed, aperture, ISO, and focus settings (although manual focusing is awkward). Furthermore, when automatic settings are used, these allow for a degree of manual override including the ability to change metering modes and make adjustments with exposure compensation. The degree of delay varies depending on how the camera is set; when the LX-3 is used as a fully automatic camera, or allowed to ‘sleep’ between exposures, there is an objectionable delay. However, when operated manually, setting focus and exposures using the toggle switch, and leaving it ‘queued up’ and ready to go, exposure can be made virtually instantaneously. I’ve used my LX-3 set at 1/2000th of a second to capture a German ICE-3 gliding along at more than 160 mph—no easy feat even with an SLR. If you ever want that ‘deer in the headlights’ feeling, try photographing a truly high-speed train full frame with a standard lens (and no 10 frames-per-second motor drive!).

I’ve found several failings with the LX-3. It lacks a built-in view finder. While there is a separate viewfinder attachment, I’ve shied away from this for two reasons: it’s relatively expensive, and I’ll surely lose it. So while in most situations the window at the back of the camera works reasonably well, it suffers in bright daylight, and I don’t like to stand around with the camera at arms length trying to compose an image. While other models have longer zooms, the LX-3’s range is limited to a view roughly equivalent to 28-65mm on a traditional 35mm film camera. This ranges suits about 85 percent of my requirements, while having the side effect of taking away the ‘telephoto crutch’, which forces me to work with more conventional focal lengths. The battery life on the LX-3 is poor, so as a result I carry three or four batteries with me, especially in cold weather. On a busy day, I can easily tap through three batteries.

Another flaw is slow cycle time, which is partly a function of how I’ve set up the camera. I expose both a RAW and large JPG file simultaneously. While jpegs suit most of my requirements, I’m not just taking photos for today, and I’m uncomfortable with long-term storage problems and compression qualities inherent to JPG format. Furthermore, RAW files offer considerably more data, and this can be valuable both for publication and situations where post processing manipulations are necessary (both topics for another day). But, I’ve made prints from in-camera jpegs up to 13×19 inches that are fantastically sharp and colorful (including the photo displayed here). And I’ve used LX-3 jpegs in books and magazines.

The LX-3 also offers a variety of in-camera color profiles with various color palates and saturation levels; while these are strictly applied to the jpegs, they allow for added creativity when composing images. It has an excellent image stabilizer, which allows for very slow shutter speeds hand-held, and can be switched off when necessary. Another distinctive tool is the ability to control the aspect ratio (external dimensions) in camera; its four standard ratios range from a square to 16:9. In addition, there are myriad controls that enable a high-degree of customization for both user convenience and file output.

Control, flexibility, and high quality are the prized qualities that sold me on the camera. The LX-3 may appear as a snapshot camera to the unknowing observer but it offers most of the control and quality that I’d expect from a high-end SLR. My intended purpose for LX-3 was as a ‘everywhere camera’ to be carried when I wasn’t carrying my full camera kit, but it soon developed into my staple tool for railway photography, as well as urban adventures and other projects. Later installments of Tracking the Light will highlight images made with the LX-3, to demonstrate its abilities as a high quality image making machine.
