Lowestoft Ness on PAN-F in Rodinal 1+50[/caption] On Monday 22 May at 0810, I stepped on to a half-submerged concrete jetty in Lowestoft, Suffolk. Awash with seawater and slick with seaweed, this tiny walkway is the easternmost point in Great Britain – and journey’s end for my trip to the four extreme points of the mainland. I looked out to a glittering horizon beneath the blazing sun as my trusty OM-4Ti’s timer beeped behind me. At 0815 the shutter clicked, setting the seal on a personal project that has seen me travel nearly 2,200 miles by road, rail, foot and flight. Many of the pictures I’ve posted about this project so far have been digital, but my chosen medium for the actual project was film – specifically Ilford PAN F, a low-speed, fine-grain black and white film. 35mm film was the dominant photographic medium for much of the 20th Century, and most readers will remember having used it for holiday snaps at some point. For a film enthusiast, though, the attachment to the medium runs a little deeper than holiday snaps, and it involves quite a bit more thought.
