I worked for a year on a book “Cracow, city of treasures”; it was a fabulous time, although hard at times. Narrow streets of this medieval city, as beautiful as they are, were nightmare to photograph. Constant struggle with converging vertical, quest to find some steps or boxes to give myself some height, search for some elevated positions and some “windows” between the houses allowing me to take interesting shots occupied me from dusk to dawn. Cracow’s treasures, the best examples of buildings of the High Renaissance architecture north of the Alps, as well as outstanding medieval buildings can be quite overpowering. To soften the images, I was adding where possible some human elements or greenery, be it some little courtyard gardens, trees growing in the street or single flowers left on benches. It was on my part a subconscious search for colour. Strangely enough, six years later, my memories fade and I see in my mind eyes only black and white images. Flowers and trees lost its appeal and only the monumental buildings and their details matter. Therefore I have converted the pictures into black & white and enjoy looking at them, less colourful but more intimate, as colour does not distract me from viewing intricate patterns, decorations, lines and shapes. This transformation made me feel very philosophical, our memories fade, we fade, sometimes too soon, but let’s hope the ingenuity and the work of architects, builders and artists will never fade.
