Following on from last week I’ve chosen another image generated by tonemapping a single RAW file. This is an example of a shot that’s not possible with traditional HDR techniques because the train is moving. Normally HDRs are built by combining multiple separate exposures, but since the train is moving, it would appear in a different place in each exposure, resulting in a great big mess!

I took this shot while I was in Galway for a few days for a conference. The weather was mostly terrible, and there were very few trains per day, but I managed to find a moment when the weather was good, I was free from conference duties, and there was a train due none-the-less. The sky also really co-operated, putting on a spectacular show.

The train is the last InterCity service of the day from Galway to Dublin-Heuston. In this case it was made up of a single six-car Diesel Multiple Unit (DMU) set. Irish Rail only have a few of these Class 22031 DMUs, which are the big brothers of the much more common Class 22001 three-car DMUs that run many InterCity services. I quite like these modern looking trains, though I do miss the old days when InterCity services were made of up regular railway coaches pulled by locomotives. I prefer the sound of the big powerful locomotives, though I think the locals prefer these near-silent DMUs 🙂
