Just a few scenes of the Adelaide CBD at dusk, mainly around the Central Markets area. The light was really nice as the sky got darker, and I got to play with some cool colours and lights on the street.
These were taken with a Nikon D70s and Sigma 30mm f/1.4 prime lens. I ended up returning the lens after a few weeks due to frequent focusing problems, but when it did get it right, the results were quite outstanding. With such a large aperture, I was able to handhold all these photos at ISO 400 with a useable shutter speed, shooting at f/1.4 much of the time. This allowed for some decent quick street shots, which were getting quite dark toward the end of this photo series.
I could have bumped the ISO up higher, but even for the standard at the time, ISO 400 on a D70s started looking fairly noisy at night if you underexposed a scene. With the current full frame Nikon digital SLRs like the D3s and D700, the quality of low light, high ISO images is streets ahead of the 6 year old D70s.
Using a tripod for night scenes, which allows sharp longer exposures, would result in quite a different look to these images. However, since almost all of these shots feature moving people or cars, there's no way to get photos like these if you're doing a 5 second time exposure.
