“I was born in 1977 in Warsaw, Poland. I had graduated from the High School of Art in Warsaw. My journey into the world of photography began in the early 90's, but at that time my biggest passion was painting. Painting helped me develop vision that was hard to create. Unfortunately I had to leave the paintbrush and canvas. A few years ago, I opened “the door” to my own world with help of a different key”... – Michal Karcz. Photo: “Last Outpost”.

“A Cornish pasty, sometimes known as a pastie or British pasty in the United States, is a filled pastry case, associated in particular with Cornwall in Great Britain. It is made by placing the uncooked filling on a flat pastry circle, and folding it to wrap the filling, crimping the edge at the side or top to form a seal. The result is a raised semicircular package”. – Wikipedia
