ISO and Shutter Speed – Workshop work

Following on from the presentation we had about ISO’s and shutter speed we were told to experiment with different techniques using the different settings we had learnt about. Using faster shutter speeds of around 1/160 to begin with, I attempted to capture movement in a crisp image, showing minute details missed by the human eye. This sort of shot is used in nature photography and sport.

For slower shutter speeds such as 1/80 and lower a tripod or something to balance and steady the camera would be required. These long exposure shots show movement as it happens, with the camera capturing the light bouncing off the subject throughout the movement.

On top of the shutter speed work, we were tasked with taking shots at different ISOs, which allows for different amounts of light in the photograph. The results being in the slideshows below.

These photographs worked well, the initial image shows the subject stood still using a standard shutter speed of 1/125. The subsequent images show the subject photographed at shutter speeds of 1/180, 1/200 and 1/350. The movement in the photos at 1/180 and 1/200 shows similar results to that of the initial photograph, however, there is still a slight blur around the right-hand shoe of the second image. This shows that the movements in the photograph, although captured, were not captured as crisply as they could have been. This could be down to the fact that the only movement was the initial jump, with little extra movement. The photograph at 1/300 also shows this, however captured the quick flick of both legs upwards without any blurring making for a relatively crisp image.

The photographs taken using slower shutter speeds were taken at 1/80, 1/15 and 1”. I feel as though these showcased how more movement is captured using slower shutter speeds. The photograph at 1” is a good example of how much movement can be captured and the blurring effect that can be created when movement overlaps over a longer period of time. I realise that to photograph shots of light graffiti and natural structures (such as rivers and waterfalls) shutter speeds can exceed 30 minutes with ease and I would like to experiment with this sort of photography in the future.

The photographs I took changing the ISO outdoors worked really well, they showcase the difference in light that ISO settings make by changing how light saturated the image is. They were taken at ISOs of 200, 400, 800, 1600. I then continued taking photographs at higher ISOs of 3200 and 6400 to really show how high ISOs affect images. The images showed the way in which photographs can become distorted from the amount of light.

These photographs from inside whilst using different ISOs were extremely dark, taken at ISOs of 200, 400, 800 and 1600 they didn’t have as much light to capture as the ones taken outside. This low level of lighting definitely impacted the images, causing some to be completely unrecognizable with the final photograph at 1600 being slightly visible.
