Panning with different shutter speeds
This exercise was practiced using a car repeatedly driving forward down a quiet road. The car was driving around twelve miles per hour. I used the same car and scene to make the images easier to compare and to achieve a more consistent set of results. I set the camera on a tripod and loosened the head so as to be able to move the camera in a panoramic fashion. I hoped for a cloudy day to minimise reflections and highlights and to enable me to shoot at slower shutter speeds without running the risk of over-exposure.
I used a Nikon 18-200mm lens, a tripod, a shutter release remote and a neutral density filter. I shot twelve images with shutter speeds ranging from 1/2000s to a one second exposure. The shutter speed was lessened by four stops with each image and was compensated for by contracting the aperture or lowering the ISO. I used a neutral density filter on the last two images (1/2s and 1”) to correct the exposure. I flicked between cloudy and shady white balance depending on the nature of the light.
I have labelled each image with the shutter speed used from fastest to slowest. The settings are as follows:
The car in this image does not appear to be moving at all. The image is completely focused and sharp and has frozen every moving part in the image. The same also applies to the next two images.
If you look very closely, you can see that the wheel hubs and the edge of the tyres on the car are starting to blur only very slightly, almost un-noticeable. The background is also starting to suffer from motion blur. The image is correctly exposed. The same applies to the next image although slightly under-exposed.
You can really begin to see that the car is moving now as the wheels and the background adopt some motion blur. A correctly exposed image.
The car is quite sharp and focused in this image while the background is very blurred resulting in a strong suggestion of speed. This is probably the best result.
The background is now streaking through the image quite dramatically and the wheels are very blurred. The car is a little blurred but is by far the sharpest thing in the image.
Well framed as slightly sharper than the previous image.
This is my favourite image in terms of aesthetics. I like the image as it portrays a sense of erratic movement, it is almost unpredictable. I find the impressionistic effect very appealing.
After looking at this image you can clearly see the difference between the fastest and the slowest shutter speeds and what each of them conveys.
