Painting With Light
Photography Club have been learning how to paint pictures with light by adjusting camera settings to make light trails.
Using the manual setting on a DSLR (Digital Single Lens Reflex camera) enabled them to take full control of the camera’s settings. They desensitised it to unwanted ambient light by selecting an ISO of 100 and minimised background light interference by using an aperture setting of F/22. Most importantly, the shutter speed was set to remain open for a period of 15 seconds and to avoid "camera shake" during such a long exposure time the camera was mounted on a sturdy tripod.
These settings allowed the children to create various light trail effects by slowly swirling coloured torch-light in front of the camera.
