What is the NPF rule?

A much more complicated and accurate rule for sharp stars is: (35 x aperture + 30 x pixel pitch) ÷ focal length = shutter speed in seconds. Pixel pitch = the camera sensor’s physical width in millimeters ÷ number of pixels in width x 1000 to measure it in microns.

What is the 400 rule?

Capturing stars as points instead of trails. 400 / focal length x LMF = Max number of seconds before stars blur due to earths rotation. Example: Full frame camera, focal length 28mm. 400 / 28 = 14.3 seconds is the longest acceptable shutter speed.

How do photographers shoot stars?

To photograph the stars in the sky as pinpoints of light, start with as wide an f/stop as your lens allows, and shutter speed of about 20 seconds. Any more time than that and the stars will begin to blur. Increase the ISO as needed for a good exposure.

The 500 rule for a full frame camera requires you to set your camera to ISO 3200 or 6400, Aperture to f/2.8 (or as wide as possible) and your shutter speed to 500 divided by the focal length of your camera. For example, if you are shooting with a 50mm lens, your shutter speed would be 10 seconds (500 / 50 = 10).
