My camera aperture was set at 6, and the shutter speed varied from 8s, 10s, and 6s.
To focus I had my cousin shine the flashlight on his phone auto-focussed the camera and then switched it to manual.
My first shots werent as sucessful because I messed up the focus.
The fourth and fifth shots were the most sucessful
When we lit the steel wool I took the photo and for some I tried two photos but I found the steel wool burned from 6-15 seconds and capturing more than one photo was really challenging. I also found the effect of the sparks was more dramatic when the steel wool was separated and pulled apart rather than compact. In the first picture, the steel wool was compact and the later ones we separated it more.
