Night Photography

Suggested Homework Due April 20th, 2016: Shoot a series of images outdoors at night. Here are some past student assignment examples: Below is a selection of images shot by students for the Night Landscape assignment.  Some fun things to try:

  • Try using a High ISO (as high as your camera will go) and no tripod (remember to keep your shutterspeed at 60 or above so it's not blurry). This will create a lot of graininess.
  • Try using a tripod and a lower ISO (like 200 or 400), but a very long exposure (perhaps a couple seconds).
  • Try having some motion in the shot for a long exposure (like this flashlight motion around the tree, below)
  • Try a long exposure combined with a flash (perhaps having the flash light up a person in the dark while the long exposure shows detail in the dark background). Try having the person run through the frame and the flash will "freeze" them.

These 2 photos by one of my students, Gary Prideaux, perfectly illustrate the difference between a long exposure night shot and a high ISO night shot. A high ISO often produces graininess, but doesn't require a tripod:

Long Exposure, low ISO, more clarity. Photo by Gary Prideaux
This long exposure shot by Mira Zaslove shows some motion on the water,
but the architecture is crisp since she used a tripod.
Here are a couple fun photos by another student using a long exposure, tripod and a flashlight:




The 2 photos below are by my student Chuck Thompson, taken in Palo Alto at Bowden Park. His Shutter Speed was 1/5 sec (which allowed for the motion of the cars). The aperture was f/8.0. The ISO was 1600, which is somewhat high and added a bit of graininess in the darker areas like the tree trunk and the roof of the train station.

Graininess is common in night photos (because of the high ISO). If you want to avoid graininess you can use a lower ISO (like 400) and a longer exposure (maybe like a half second, with a tripod), and perhaps a lower number F-stop (wider aperture), something like F 2.8.
