Slow shutter speed:
This image was shot at the default 1/60th second shutter speed setting. The camera shutter speed is too slow to 'stop' the club in mid-motion. Movement that occurs while the camera shutter is open is reproduced as a blur. To resolve this issue, set the shutter speed on the camera to 1/1000th second or faster.
This example shows what happens when the shutter speed is too fast for the amount of light where you are filming. This video was shot with the camera set to 1/8000th second. To resolve this issue, move to a brighter location or reduce the shutter speed setting on the camera. You do not need to anything faster than 1/2000th second to record a perfect swing video.
This picture was taken under the same amount of light, using the same camera as the two pictures above, with the camera shutter set to 1/2000th second. The club appears sharp, however the image is not underexposed.
The overall 'fuzzy' appearance of this example occurs because of the low resolution of the original video. This example is 320x240 resolution. The second picture shows what the image will look like if the resolution setting on the camera is increased. Please note that some cameras do not allow you to change the resolution setting.
Samsung SC-D372 (720x480), 1/2000 shutter, highspeed ballast fluorescent lighting.
Because of the flickering nature of standard fluorescent lights, the camera is unable to adjust to the rapidly varying light levels. This problem can only be corrected by filming under a flicker-free light source such as natural light, incandescent/halogen lights that use a glowing wire filament, or "flicker free electronic ballast" high speed fluorescent light fixtures.
A mix of fluorscent and natural lighting will result in a slightly more stable picture, however the white balance circuit on the camera will still be affected and will result in the color shifting effect visible here.
