Painting with lights Evaluation

For my Final Portfolio, I choose Painting with lights. I put the ISO to 100, Shutter speed to 2.5 seconds and Put the focus on manual. We used a torch to create the light and a dark area to make it stand out more and so  you could see the light more clearly without any other light crossing over it.

Crop the images
Make sure all other light objects are out off the way
