When conducting my research I discovered that a useful technique in night photography is the long exposure. The effects that can be captured with a long exposure can producestunning results and have as well as producing good quality images. The most important tool that I needed for this type of shoot was a sturdy tripod, and as well as my DSLR camera that allows for long exposures.
Below is a perfect example of a long exposure by Tom Anderson. I came across his work on blogger. He evidently knows how to use different apertures and shutter speeds to come out with very good exposures.
But the most important thing is I did try.
I still have a long way to go in terms of knowing the different exposures especially how they relate well things such as f stops, aperture, etc. I'm hoping to achieve this by the end of the semester so that I will be able to take much better pictures. This will also help me get a better understanding of how aperture and shutter speed together are used to control the different exposures.
Mortion Blur
Lower ISO ratings produce color-accurate, smooth and aesthetically appealing images and this requires ideal lighting conditions. However, there are some subjects that you want to photograph in low light conditions. Or, you may want to stop fast-moving objects (a humming bird, a race horse or a carousel). In both situations, you need higher ISOs to capture those images with an acceptable exposure. Unlike film, with a digital camera you can increase the ISO with the touch of a button, and this flexibility makes it much easier to get the image you want. So with the higher ISOs, you can use faster shutter speeds to eliminate motion blur and/or camera shake. In the event that you want to use motion blur creatively, then decreasing the ISO is simple, and you can then decrease the shutter speed (less than 1/30s) to achieve the desired motion blur and still have smooth, noise-less images.
