It's definitley not a process to just throw any photo at. Not baggin' on Joe here, but you can clearly see the difference in the specific shots that Minh chose to work on. Also in the night time front-of-house shot (see, that was Joe's ). If not done with the right imagery it will either not seem much different from a regular shot or go into trippy psychedelic land And yeah, you could literally do as many exposures as you'd like
