Requirement 1 & 3
I took this photo in discovery park and satisfies requirement 1 & 3. I put steel wool into a whisk and connected by a rope. And then i rotate the rope. I set my camera to manual control mode so i can control all the settings. I set aperture to f/11 because i took this photo during the golden hour so there is a sufficient light, which means i need a small aperture to do the long time exposure. And then i set shutter speed to 30s, which gives me a plenty of time to do the light painting. Then i set iso to 100 to get a less noise photo. I did the post process with Lightroom by increasing the sharpness and saturation.
