Objective :To demonstrate how shutter speed effects movement. Altering shutter speed also determines the levels of sharpness obtained.
For this exercise i selected ‘S’ mode on my Nikon. This is ‘Shutter priority’ mode. I have a range from 30 (1/2 a minute) to 1/200 (200th of a second) with the standard camera. (This can be increased using high speed flash sync to 1/4000th with compatible flashguns.)
Initially I intended to use a fountain as my subject but due to wisdom teeth problems and thunderstorms i decided to use a closer, easier object instead as i wanted to stick to my deadline and not fall behind on further projects.
I will however be re doing this exercise as planned, but for now i think I’ve demonstrated the objective of this exercise.
I have chosen the following pictures that best represent the difference between shutter speeds. these were shot at 30, 6, and 1.6, to demonstrate a long shutter speed and 1/60, 1/125 and 1/200 for the fast shutter speed. The ISO remained at 400 throughout.
1/60th of a second
1/125th of a second
1/200th of a second
As anticipated, a longer shutter speeds makes the water look silky and soft, almost creamy. The short shutter speed captures the water more dramatically resulting in a much sharper image.
I have also noticed that a longer shutter speed shows the background in more focus, whereas the later shots at 1/125 and 1/200 have blurred backgrounds. The background starts to be out of focus around 1.6 of a second.
There were a few issues I faced with this exercise. In theory it was pretty straight forward but i hadn’t taken into account the flash bouncing off the ceramic bath surface, the white background behind the water (my results may have been more noticeable if there was a different colour behind the water – especially for the long shutter speed shots) and the amount of light. For the long shutter speeds I had to turn off the bathroom light and take the pictures almost in complete darkness. I would like to see how this exercise would turn out if I used an outdoor setting with a constant light source. The built in flash became necessary at 1/30 making the pictures look very different to the shots taken with a long shutter speed.
My favourite image is the 1/200th. I love how the water looks sparkly and sharp and the contrast is vivid. It feels much more ‘artistic’ than the other shots.
