No PS work here except crop. This is a single exposure photo. I used a children's toy in complete darkness to expose the sensor on my camera. The light ball in my hand was done by holding the toy above my hand for about 5 seconds of the exposure-then I made the swirley line that moves and changes color across the photo. The "galaxy effect" balls are short pulsed in different spots of the camera's field of view. Keep in mind this is a single shot and no Photoshop done except a crop. Please critique.
