In week four, our workshop was focused on shutter speed. Shutter speed is the speed at which the shutter of the camera closes. A faster shutter speed means that the lens is open for a shorter amount of time, and thus less light enters the lens- creating a shorter exposure.
Whereas, a slower shutter speed gives the photographer a longer exposure, meaning that more light enters the lens.
For our task we went outside and experimented with both fast and slow shutter speeds.
I liked the effect the wind movement created in this particular shot. Although Sapphire wasn’t moving, the wind was strong. I chose to use a fast shutter speed meaning that the photo was clearer.
For this shot, I took a photo of Sapphire mid-jump. I used a fast shutter speed in order to achieve minimal blur, meaning that the photo was clearer. A fast shutter speed achieves an effect that freezes action, and is often used to photograph moving objects-such as birds.
Shutter speed- 1/40 F.13
For this photograph, I used a slower shutter speed which meant that the image was brighter.
For the portraits of Sapphire, stood in front of moving vehicles, I used a slow shutter speed. I asked Sapphire to stay still. The busy road behind Sapphire provided a background with lots of movement which created an interesting, motion-blur effect.
Slow shutter speeds are often used to help illuminate darker scenes.
I used the same busy background for this shot with Rai. But this time, the participant was moving. This created an interesting effect.
ISO Task- Extra Credit
As part of the extra credit task, we were instructed to set our cameras to manual mode, set the aperture to a middle F stop and put the shutter speed to 160.
I then experimented with different ISO levels.
ISO is the camera’s sensitivity to light, it is a setting which determines whether the photograph will be brighter or darker.
For the three photographs shown above, I used a low ISO setting. A low ISO meant that the camera had less sensitivity to light.
For the shot above, I used a higher ISO setting. The high ISO value meant that the camera had a higher sensitivity to light.
