The Old Town Square is one of the main highlights of Prague, so it is visited by many tourists during the whole year. So street artists perform all kind of stunts there. And people also play with soap bubbles. This photo was taken at the end of the afternoon when the sun was down, which gives an interesting mood to the image. At the background it can be seen the Old Town Hall Tower.
This is cool. I like how the color of the bubbles stand out. Really cool shot.
I am glad that you liked the photo. The idea of the composition of the photo is that the bubble stands at the centre covering some of the people and the tower and at the same time, and it reflects some nice the colours. Thank you for your nice comment.
