You can be very creative with photography, either in camera or in post. Long exposures, double exposures, light painting. They are the kind of things you can do in camera. in post you can do all that in theory and then some.
This is both light painting and long exposure. Very simple really, just make sure your camera is on a tripod the room is dark. With a touch while the shutter is open light paint. Going over areas you want to stand out more.
Shot with flash and low ambient light to bring out the subject. I then moved the image into photoshop and edited in the sparkle effect. You can do sparkles in camera but that would mean doing a long exposure and over exposing the subject, not the look I was going for.
In photoshop you can create actions and even purchased action from website. This image was created by using an image from Unslash.com and the Energy action by Seven Style.
