I've been experimenting with 10 stop neutral density filters and long exposures. Here I am twirling in a string of blue Christmas lights. My body is invisible and you should be thankful as I was nude. Yes, I am a dirty old man! I was hoping for a blurry ghost but ended up with Tinker Bell on crack cocaine. The Nikon remote app Snapbridge cannot control exposures longer than 30 seconds: disappointing. When will photo app developers get it through their thick Millenial skulls that the user, (photographers), should have absolute and unquestioned control of their cameras? If I want to set the device to self-destruct it is none of your business!
