Shutter Speed Exercises


In this picture, I was by the umbrellas and the steps. The problem was that the picture kept getting taken at the wong time- either too early or too late. This picture is a good example of stop action because the person is frozen in mid-air and it isn't blurry. Before this shot, we used a slower shutter speed and it wasn't high enough. There was a lot of blur and we also had to set the ISO higher as we made the shutter speed faster so the image wouldn't be dark. To improve this image, I would take the picture from another angle so the viewer can tell that the person is really off the ground.
We were by the lunch courts for this picture. There was a problem with the ISO and shutter speed because when we turned the shutter speed up, the picture became way too bright, so we had to lower the ISO. It was on the lowest setting but it was still way too bright, so we had to lower the shutter speed as well. This is a good representation of this skill because the person is running but is stopped without being blurred. Before getting this shot, we tried higher ISOs and high fstops and the exposure was higher. But since it was too blurry and bright, we had to lower the exposure and make the shutter speed higher. Maybe the picture could have been zoomed in a little more so it's easier to see details.


This was taken by the office and umbrellas. The problem was that the picture was taken at the wrong time, so the leaf had either fallen or hadn't fallen yet when the picture was taken. This was a good representation of stop motion because the leaf is frozen in the air and it isn't blurred, like motion's occuring. We used the same settings for every picture we took of the leaf because the images didn't come out too blurred, bright, or dark. We could have picked a different location to drop the leaf because the leaf kind of blends in with the background.
The picture was taken by the gym. Some problems we had were the person would run too fast, so by the time the picture was taken, they were already out of the shot. Since the background is in focus, and the person is blurred, it was a good representation of motion blur, showing what's stationary and what's not. We used higher ISO and shutter speed settings before taking this shot, but it wasn't working out because the person kept coming out sharp and in focus. The person could be a little less blurry so they don't seem like a random blob in the picture.

We took this picture by the lunch courts. Some trouble we had was we coudldn't get the lighting to turn out right. When we had a fast shutter speed and a medium ISO, the picture was too overexposed. Then we lowered the ISO to the lowest setting and reduced the shutter speed, and the image turned out a little darker and the person running was more blurred like we wanted. The person is blurred, so it is a good representation of action for motion blur. Before getting this shot, we had higher ISO and shutter speed settings. The shutter speed could still be lowered, since the image still looks a little bright.
