Last Friday, 11 March 2016, I went up to my favored Irish local location; Islandbridge Junction. This is a handy place for me.<\/p>\n

This\u00a0is great place to catch a freight train exiting Dublin\u2019s Phoenix Park Tunnel on a bright clear day, yet can be visually problematic on a dull day.<\/p>\n

On this day, I thought it would be a good place to experiment with a Lee graduated neutral density filter as a means of controlling contrast and allowing for a more effective overall exposure.<\/p>\n

The filter I use offers subtle 2\/3s of a stop gradation. This is adjustable both up\/down and rotationally left\/right.<\/p>\n

I made a few test photos with and without the filter to gauge my exposure before the IWT arrived with Irish Rail 088 in the lead.<\/p>\n

A similar effect can be accomplished digitally, yet the digital effect doesn\u2019t add information to the RAW file, but only makes a visual adjustment in the final image.<\/p>\n

In other words to apply the filter digital may be viewed as a \u2018correction\u2019 rather than an in-camera technique. Yet, it is often easier to apply a filter in post-processing than in the field.<\/p>\n

I\u2019ve used both methods depending on the circumstance.<\/p>\n

Below are some results.<\/p>\n

\"Test<\/a>
Test photo to gauge comparative exposure. This was made without the filter. My concern is getting adequate exposure in both the sky and foreground.<\/figcaption><\/figure>\n
\"Test<\/a>
Test exposure with the graduated filter. Here I’ve been able to lighten the foreground slightly while holding detail in the sky.<\/figcaption><\/figure>\n
\"Here's<\/a>
Here’s a test view using the filter. I’ve achieved a good overall balance. (Sorry, the filter won’t make the sun come out.)<\/figcaption><\/figure>\n
\"Here<\/a>
Here we have the ultimate objective. To make a balance image of Irish Rail’s IWT Liner. It really about making the most of a gray engine on a gray day.<\/figcaption><\/figure>\n

This gives a nice overall of my experiment, but in the middle of all this I got a little greedy. Using my zoom lens on the FujiFilm X-T1, I made a tight view of the IWT (with the filter).<\/p>\n

As is often the case with last second changes, I didn’t get my exposure quite right. My feeling was that the RAW file was about 1\/3 of a stop too dark.<\/p>\n

\"Nice<\/a>
Nice try, but my exposure was a bit dark.<\/figcaption><\/figure>\n
\"I<\/a>
I imported my RAW file into Lightroom and made a variety of small corrections. First I altered the level. I also lightened up the entire image slightly and warmed up the color temperature. Is this an improvement?<\/figcaption><\/figure>\n

As with most of my photography, I consider this a work in progress. In all likelihood, before long I\u2019ll be back at Islandbridge Junction to further refine my experiment.<\/p>\n
