The bonus of arriving at a location early, and when it’s a non-event day, is that you may have a chance of capturing something different. This is a 25 second exposure taken on the platform at Buckingshire Railway Centre using a 10 Stop ND Filter. I like the way the clouds look like they’re following the track. This is still an a active freight line, unfortunately a train passed through 10 minutes later.
KIT TIP: I’ve been using the ND Filter Calc App (available from Google’s Play Store for free), to calculate exposure times, and I have to say for me the calculations are pretty much on the button. That said, you can always play with increasing or decreasing exposure time once you’re familiar with your kit performance.
