Sunrises Dec 2020

Shown here are 4 sunrise sequences taken by my webcam during December 2020. No music, just color. Technically the webcam is a bit special. With the help of a friend, I have followed the idea of using a normal camera as a webcam and my iMac for control. Since it is basically very easy and not expensive I thought my experiences would be useful to someone who has a particularly good view for his webcam. So here is sort of a step by step procedure. 1. Camera, Canon Powershot A510 or other compatible camera. See a list here. http://www.gphoto.org/proj/libgphoto2/support.php I had trouble with my powershot A30 so I bought a used A510 on Ebay for about $20. 2. Buy a USB cable (powered) to reach from computer to location, Maybe about 15 m. 3. Buy 110-240V adapter for Canon camera DC 3.15V supply; mine is called ACK-800. Batteries last only a few hours. Mine cost about $15 and has been going steady for 5 years. 4. Mount camera in protected box or inside a window. I am using a small plastic refrigerator box with a window cut out and plexiglas glued in. This is mounted on a covered balcony. 5. Download and install gphoto2: This is done by first installing Homebrew ( http://brew.sh/ ). I am able to see the photos as they are taken with Preview on my Mac and to send them to other websites on the Internet. Contact me if you want to know details about programming with gphoto2.
