I have been depending on the high sensitivity of my camera to take many photos in poor light. However, I realised that I missed out a lot of details and richer colour if I could just lower the ISO, close the aperture down and increase the exposure time. So tonight, I experiment with low shutter speed, low ISO of 100 and small aperture and here are the results... all taken at the Miri city fan ... time: 6:35PM to 7:00PM. As it was raining slightly, black cloud everywhere, it was quite dark.
f/18, 6 sec
f/18, 15 sec
f/10, 30 sec
f/10 15 sec. Notice that I halved the exposure time and the difference was not really great.
f/8, 8 sec
I cropped the bridge from the picture above.
