I wanted to practice using my camera’s shutter speed to capture motion, and I thought King’s Island Amusement Park was the perfect place to do it.
I attempted to use a technique called panning on this photo. I used a slow shutter speed (1/30) and physically moved my camera with the object I was trying to capture. So as the merry-go-round went around, I turned my head and camera at approximately the same speed as the horse I was shooting. The background blurs, but the horse is in focus, sort of.
This has an even slower shutter speed at 1/13. It just means the time that the aperture was open was longer, allowing more light in, but also capturing movement.
In this case, I was trying to capture the motion by allowing it to blur at a slow shutter speed of 1/8.
This one has even more blur, not because I changed the settings, but because the Scrambler was going around faster. You can see that the people in the background are pretty well in focus because they are mostly standing still.
These swings are actually moving around, but I froze the motion by using a very fast shutter speed at 1/4000. Because this speed didn’t allow very much time for light to enter the camera, I opened the aperture up to f/5.6, and changed the sensitivity of the receptor (ISO) to 800. The higher the ISO number, the less exposure to light the receptor needs. You might remember buying 100, 200 or 400 ISO film before digital cameras became so popular.
I wanted more motion or blur, so I changed the shutter speed to 1/60, which is a lot longer speed than the above photo was taken with. I had to change the ISO and f-stop accordingly, or the picture would have gotten too much light, turned out very dark, and been over exposed.
I froze the motion of this fast roller coaster called the Vortex, by using a fast shutter speed of 1/800.
And I blurred the motion of the cars going around the loop by using a slow shutter speed of 1/30. Again, I had to reduce the sensitivity of the ISO, and close the aperture to a 1/29 so as not to get too much light into the camera.
I froze the motion here, but this photo also points out a problem I was having with the exposure. The camera has to be able to measure how much light is out there so it can know how to adjust the settings. If I change the shutter speed, the camera automatically adjusts the f-stop so that the picture has the right exposure. (I could adjust everything manually if I wanted to, but why?) The camera measures the amount of light by metering. I’m going to talk more about this later. The problem I was having was that the sky was so very bright, the people on the car did not come out clearly or with much detail.
You can really see the problem with this photo. The sky is so light, it caused the meter to read the scene as a very light location. You can see detail in the clouds, but the leaves and ride came out almost black. The camera didn’t have enough time to gather the information from these darker objects.
In this picture the people are a lot more detailed because the surrounding area is about the same brightness as they are. It has to do with the way the camera meters the light and I’m learning how to better control this. More later.
Another frozen shot with a fast shutter speed. I did a better job of metering the light on this one so that the people in the car are visible. Can you see how this roller coaster doesn’t have actual cars to contain the passengers? Each person has their own little seat with a small toadstool in front.
Not in a million years.
This is as close as I will likely ever get to this big boy.
I enjoy the roller coasters very much from my viewpoint on the ground.
