During my walk last night through Old Town Bratislava, the sky showed some interesting patterns. My camera had a prime 50mm f1.8 lens on it. I placed it on a rail of a bridge that faced the Bratislava Castle. The exposure was 4 seconds long with an ISO of 100 and the aperture set at f8. When just walking around town, I will frequently put on my canon 50mm f1.8 lens. It is very light and captures excellent pictures. Last night Bratislava was hopping with several musicians performing throughout Old Town. There is a music festival (one of many throughout the year) going on until Sunday night.
