How I shot and edited it: The Second Severn Crossing

Second Severn Crossing - how I shot and edited

The image above is a long exposure taken of the Second Severn Crossing, a motorway bridge that crosses the River Severn, just outside Bristol, England.  I have been asked a number of times how this image was processed, what software/plug-ins were used, so I thought it would be a useful exercise to explain it here.

Shooting the image

I had been thinking about this shot for a while and I knew that there were a couple of important elements that I needed to consider when trying to capture the image:

  • I was really keen to get low, relative to the bridge, and shoot a wide-aspect image across the river.   Fortunately, there is a footpath that runs along the river bank, under the bridge, that is easily accessible by car (Google maps link).
  • I wanted to capture a long exposure so I could contrast the movement of the clouds against the static structure of the bridge.  Therefore, there was no special planning in terms of weather or time of day, as I was happy with a cloudy sky in the middle of the day, as long as there was a strong wind – fortunately, over the 2012 Christmas period, the UK offered those conditions in abundance.
  • I wanted to fill the frame with silky-smooth water, so as the River Severn is a tidal river with one of the largest tidal ranges in the world, I ensured that I would arrive at the location around high tide.

The image, as captured straight out of the camera, is shown below:

The image was taken at ISO100, 12 mm, f/10, with a 5 minute exposure (299 seconds to be precise).  I used a 2-stop graduated neutral density filter to evenly match the exposure of the sky with the river, and used a 10-stop neutral density filter to produce the long exposure.   As the highlights of the scene were easily contained, I over-exposed the image to ensure that I captured the maximum amount of movement in the clouds, knowing I would be able to correct the exposure/contrast during post processing.

Processing the image

The processing of this image was performed in Adobe Lightroom 4.

The first step was to convert the image to black and white using the B&W selector in the colour panel (on the development pane).

Given the significant amount of foreground, I decided to crop the image at this point, using a 2:1 aspect ratio, to give the wide-aspect image I was after and to stop the foreground being a distraction during the rest of the processing.

Cropped to a 2:1 aspect ratio

I then needed to address the lack of contrast and over-exposure of the initial image.  Therefore, I set the white (+33) and black (-40) points and adjusted the contrast (+40) to set the overall exposure for the image.

Initial exposure adjustments made

I then applied a graduated filter to the sky (shown below) to adjust the exposure (-1.74), contrast (+100), clarity (+100) and highlights (+12).  I wouldn’t usually increase either the contrast or the clarity to +100, let alone both, but in this instance doing so acts to bring out a full range of tones within they sky and so emphasise the movement captured in the clouds (the increase in contrast/clarity is also a very good way of highlighting any dust spots present in an image!).

Next, I applied a graduated filter, from the bottom of the frame, to the water (shown below).  I used it to increase the exposure (+0.80) and reduce clarity (-100) in order to brighten the water and reduce the local contrast to give that bright, smooth water effect that can be key to an image such as this.

When applying the graduated filter to the sky, it also acted on the bridge in the top left corner of the frame, making it overly dark, losing detail.  Therefore, I used the adjustment brush to paint a mask over the affected portion of the bridge, using a low flow, in order to be able to build up the desired effect gradually.

To the adjustment mask, I applied an increase in the exposure (+1.08) and shadows (+18) to bring out some of the detail in the bridge that was lost after applying the graduated filter over the sky.

I then applied a graduated filter to each corner on the right hand side of the image, shown below.  The top graduated filter was required to subtly blend a vignette caused by me stacking the 10-stop filter and the ND filter holder.  The bottom graduated filter was required to tone down the water at the edge of the frame.  The exposure was reduced in both instances.

The final edit that needed to be made to the image was to remove all of the dust spots (you’ll be glad to know I’ve since had my sensor cleaned) and hot pixels (the bright white pixels that result from the extreme exposure time) to give the final image:

So there you go, using a few relatively simple edits, it was possible to produce this high-contrast black and white long exposure without the need for any additional plug-ins or software packages outside of Lightroom 4.  The initial image may have lacked impact and that can often be the case with long exposure shots, however by shooting in raw, you can exploit the captured detail to create the image you had envisioned.

    Superb image and explanation……i liked the way you explained it step by step with its effect on the image….!!

    Great image thanks Elliot! I’ve been planning for a while on getting over to the bridge to get a long exposure shot and this should help me get my butt into gear (I’ll be on the better side of the bridge though over in Wales haha)

    Really nice photo mate

    Excellent post Elliot! I really enjoyed learning how you use the graduated filters in your post-processing. I never think of it except for exposure.

    i’m just a beginner in this digital photography world having been newly acquired my nikon dslr d3100 and seeing this kind of shots really amazes me…when should i work also with this kind of shot and produce a good edited copy of it like sir hook had done wonderful and really amazing! i really love arts especially photography…thanks for your much informative lecture on shots processing really complete step-by-step…more power!

  • Joe N

    I’ve read lots of “How I Shot” posts, never seen one that made me feel like i was actually watching them edit it. Thanks for providing the shots after each step, and the numbers! Only thing I would have wanted more would be higher res versions so you can really see the effect each step has. Thanks!

  • Andy

    Thank you Elliot.
    Really great to see an accomplished photographer sharing knowledge like this. Most of my photo friends are not willing to pass this sort of info on. Respect!

  • jumbybird

    Relatively simple edits… :)
