This is not a new technique by any stretch, and it's honestly not new to me either but it has been like 10 years since I visited this craft! What exactly is PwL? Well, it's basically a super long exposure taken in the dark (either a blackened room or during the late midnight hours) and the subject matter is then 'painted' with light by something like a flashlight, glow stick, or even with the pop of flash in the dark. The end result can be quite dramatic as the different lights hit the cameras naked sensor.
Here's a few examples that I played with in my home with the help of my kiddos. (Please keep the laughter on the subject matter down to a minimum as it was only by some massive amount of begging that I got the kiddos to help me at all! .. and some bribery with Oreos always helps!)
Questions like, How can we shoot these people to look more like the comics they were portraying? Would it be possible to create some stop action motion to replicate the energy in anime in addition to the neon looking stripes. How can I do this in my typical style of little to no post production work?
So a few test shots later on that idea, and I came up with these images that I captured all by myself ...
