Shutter speeds photography and evaluation

Above my first attempts at playing with light and slow shutter speeds,the camera only captures singular short lines of movement in my first attempt. This shows the shutter speed was to fast to capture any significant movement with the torch.

I then adjusted the shutter speed to a slower speed of 4 seconds,this allowed the camera to capture many light streaks created within the four seconds of movement. This showed me that i the slower the shutter speed the more movement the camera can pick up allowing the light created to become more interesting and intricate.

This therefore made me wonder if recognisable images could be created using light and coloured tourches. I decided to be creative and create intricate imagery with the torches to see if the camera could capture the movement of the torch.

 I then set the shutter speed to 30 seconds and waved multiple coloured torches around which created an overexposed effect. The picture looks very layered with the different widths of the light streaks and opacity of the light streaks. For example the orange streak is almost see-through wear as the green and blue light streaks are closer proximity to the camera making them more overexposed creating a bright white 'glow' effect.
