Frame Within a Frame

For this technique i decided to go around london and shooting at various different locations taking photos between buildings and through walls and gates. These act as a frame within the photograph. When shooting between two things, in my photos these are buildings. To achieve this i set my apeture about f5.6 which aided the photo by not letting alot of light in but not to much to over expose it. In addition to this i set my ISO to around 320 as the locations already have sufficient lighting. My shutter speed was low as this meant i could allow the photo to be exposed to a little light without have to end up with a massive blur as my final product.
