Before the Decisive Moment

by Aaron Hockley on April 21, 2006

Doug Plummer has posted a good little piece about the “Decisive Moment” in photography, specifically how to recognize it before it happens.

It got me to thinking about anticipating the moment as it relates to railroad photography.  In the examples Doug gives, he is able to spend time thinking about the scene, make an observation, switch lenses or equipment as needed, and then take his photo, often offering up the line of “Please continue to ignore me” to his subject.

Depending on your railroad subject, a similar approach can work.  If one is taking photos of a static subject such as a signal, depot, or stopped piece of equipment, then the notion of a decisive moment is lessened and one can take several versions of a photo only to later cull and reveal the best.

If you want to shoot a moving train, there’s only one chance to get the shot. Unless it’s a planned runby, that train isn’t going to back up and come by again, so planning the shot and anticipating the decisive moment is crucial to ensure the best photo possible. Here’s a few of the things I try to think about as I plan a shot… some are railroad-specific, some are more general:

  • Lighting: where is the sun? Is it cloudy? What parts of the train will be well-lit? Are there shadows along the tracks that might cause problems?
  • Moving objects: is there a chance of an automobile, person, or other moving object coming into my photo at the last minute? Can I compose the photo to avoid this?
  • Roof growth: are there power poles or other objects that will be behind the train? Can I compose the photo to prevent a transmission tower from “growing” out of the top of the locomotive?
  • Train size: how tall is the train? This sounds obvious, but being able to recognize the height of a locomotive or piece of rolling stock is essential when planning the composition.

Occasionally a gem will appear from a grab shot, but doing a bit of thinking and planning helps one to anticipate the decisive moment.

    I just made my first attempt ar rail photography this afternoon at the Sacramento Amtrak depot. I was able to photograph the departing Capitol Corridor 357 and arriving 701, plus a passing frieght.

    At this point, I think my biggest problem is camer shake. I was using a Canon 75-300 mm lens at about 200mm to photograph a UP frieght passing through the depot on track 2 without a tripod. I’m not sure if it was camera shake or locomotive shake. Four units led the frieght!

    It’s also my first attempt at RAW. I’ll process and post a few pictures on my blog tonight.

    It think the decisive moment for shooting moving trains (or other moving objects) is not just the topics you and Mr. Plummer point out, but also when will the moving train be in the most attractive point in the photograph. Take for example http://www.dogcaught.com/2006/04/13/slow-gorge-evening/ below. On your photograph of the garbage train coming through the truss bridge you had to decide what is the moment I want to capture?

    Technology has allowed us to cheat a bit on that moment with cameras that shoot upwards of 5 frames per second. If you rattle off a few you can usually get one that is just right. However, I firmly believe the ideas you and Mr. Plummer bring up still have to be considered to be sucessful.
