LG's G4 cellphone is (almost) perfect for TVL photography

I've just moved to the LG G4 phone, and was excited about its camera's manual mode. Tonight I had a chance to try it out. I photographed this restaurant, which has a line of white LEDs around its windows:

By using the camera's manual settings, I captured this image:

The time-varying behavior of these LEDs is very easy to see with the naked eye, and may well be one of the easiest subjects for vision jiggling.

To get this image, I selected the following settings:

  • Manual focus (so that it would not be trying to focus while taking the shot)
  • ISO 500 (to underexpose the image so that I get the lights, not the whole scene)
  • 1/8 second (to capture for long enough to give me plenty of dashes in the traces)

The primary weakness with the G4's camera is that there's an appreciable delay between pressing the button and the shot being taken, and since you have to keep the camera moving it's unpredictable what you'll capture. The solution is to take several shots until you get what you want. Aside from that, though, and the lack of optical zoom (which isn't too much of a problem for this type of photography), the G4 makes a great pocket tool for the photographer of time-varying light sources. Highly recommended.
