I have a little infrared remote control that I can use to trigger my camera. I use it all the time for photos with long time exposures. It helps reduce any vibration that I might give the camera by pushing the shutter button.
- I think there is some potential for some interesting photos with flash light shining in the camera to block certain features. This allows the viewer to use his/her imagination to fill in the missing part of the photo. I may explore this theme some more.
