This image I took sometime ago at an underpass in Canterbury. I loved the symmetry of the structure of the bridge supports and the colours and vibrancy (is that a word?) of the graffitti. I tried to get a good symmetrical image by cropping after taking the original. I also boosted the shadow detail to create a balanced image and then optimised contrast and boosted the colours. Getting front to back sharpness in low-light with a compact point-and-shoot 4MP digicam was tricky..getting enough light in demands a more open aperture, which in turn means shallow depth of field. Using a smaller aperture (higher f) gets the depth of field, but lets in less light, and thus camera shake is an issue. So, I bumped up the ISO to 200, wedged myself into one of the support structures for stability, used a moderate aperture of 5.6 (which on a digital compact with a shorter focal length means greater depth of field than the same aperture on a DSLR), and shot in RAW (yes, it had RAW, which was a major benefit and almost unheard of then on such cameras) to get a sharp image with detail in the foreground and rear. I really like this image.
