Steel Wool Exposure

On the first early days of starting photography, we were experimenting with the shutter speed on our cameras. This is basically changing the time in which the shutter allows light into the sensor. The longer the speed the more light let into the camera. This means quite a few things. Firstly if you dont change any of the other settings it means the overall image is brighter. However there are a few other effects this has on the picture. If you reduce the ISO to as low as possible (100) and then improve the aperature to a high number such as F22 it allows you to take photos with a shutter open for multiple seconds. The pictures tend to come out a lot clearer and in focus in comparison to other shots, so these are perfect for landscape photography.

Another good thing this allows, is capturing light trails.  The photos below are myself and friends expecting with capturing the light trails of burning sparks. The pictures are created using sparks of steel wool being swung around on the end of wire, while being in a metal container (whisk), which would project the sparks in multiple directions. I can then set the camera on a long exposure and capture the trails and shapes it creates when coming in contact with different surfaces. 

Below are a few photos from several locations I did this in. The photos had to be dark areas or at night to make sure you could see the sparks.
