Nathan Walsh was born in 1972 and is a contemporary realist painter living and working in Wales, United Kingdom. Walsh is known for his large-scale paintings, some measuring up to nine feet in width. He travels abroad to large cities like New York to research his compositions, and then returns to his studio in Wales to create each piece. He sketches the basic composition of each painting on a postcard-sized piece of paper. Then, he photographs specific areas of the city that he chooses to paint. When he returns to his studio, he compiles as many as 1000 images to prepare a composition for a new painting. His underpaintings are very intricate and architectural.
