Nighttime Time Lapse

The next Arduino project is timelapse star photography. I have a Nikon D40 which is controllable via an IR port. I found a library online to use an Arduino with an IR LED to trigger the shutter release. Once the camera is set up to properly take a nighttime exposure, the plan is to set it up overnight to do a timelapse of the stars going by.

First up - figure out how to take a decent nighttime photo using the D40:

D40 Night Shot

This was a 30 second exposure at f/3.5 for 30 seconds, ISO 800. What's with the redness????

Some more reading led me to the theory that my exposure times were too short and the ISO setting was too low. Well, the maximum exposure time on the D40 without using a remote is 30 seconds. Time to build a remote!!!

D40 Remote Arduino

A way overpowered remote - an Arduino Mega 2560 with a MakerShield and an IR LED.


3-17-12 Long Duration

A little better. ISO 200, f/3.8, maybe 100 seconds exposure. Getting there.
