There’s something to be said for NOT having a plan. I tend to plan my photo excursions, so as to incorporate all the big sights I want to shoot. Really, you have to do that, or else you wander somewhat aimlessly and directionless while time slips by. However, it also helps to build in a little cushion, so that you can wander a bit after shooting the big sights, so as to explore and see what you happen upon.
This is a perfect example of that. I had just been shooting at Trinity College in Dublin, and having been kicked out for using a tripod (stupid rule!), I ended up with a little more extra time and thus began wandering a bit. I was somewhat aiming myself toward St. Stephen’s Green, and en route came to this bank building. I just loved the light and the architecture, and the gentle curve of the road.
