Light painting is a photography technique, it is made by using a hand held light source such as a flash. You can make a light picture using a long exposure that looks like graffiti made with light.
How it works
Light painting is made by a flash of light freezing the subject and then a hand held light draws a picture over it. You have to have to put the camera on a tripod because of the slow shutter speed. You have to put it on the tripod because if you don't put it on a tripod then your picture will be blurry due to the long shutter speed. The camera records all the light that comes through the lens a long or short period of time allowing multiple exposures and light trails. Aperture settings
Light Painting
This was our first ever light painting, as you can see it didn't go as we thought. The painting was too exposed to the flash, which meant that we couldn't see the subject that well also in the background you can see the creases in the back drop as in the other paintings it is fully black. Another thing that was wrong with this painting was that the shutter was open for too long so we could of improved this painting by less light from the flash and closing the shutter speed on the camera.
We thought about what went wrong with our over painting and we improved on it for example we made the shutter speed faster also we didn't expose it as much a last time. We experimented with different shutter speeds we started off with eight seconds then we moved on to fifteen seconds but we decided that we would try a multiple shutter speed which is literally how long we want it to be but the longer you keep the shutter open then the more light gets in. We also learnt about aperture settings. When you are in a dark room or a very light room you have to adjust the aperture settings. For example when you are in a dark room you widen the aperture (the widest is usually f1.8 depending on the lens) and in a very bright space you might need to narrow the aperture (f22 is a very small aperture setting).
