My Chosen Theme - Documentary Photography

Based on looking at the V&A Theme Tours, my chosen theme is Documentary. I decided to choose this area of photography as it allows me to focus on a chosen subject in more depth. Originally, I was interested in doing Landscape Photography but then changed my mind as I do not live near the countryside and do not want to take photographs of city landscapes. I am thinking of focusing on the subject of nature for my Documentary Photography as it allows me to explore landscapes when I get the chance but also close up of flowers and plants.
