Testing Multiple Pi Camera Options With Python #piday #raspberrypi @Raspberry_Pi

Matt writes via raspberrypi-spy.co.uk:

It’s easy taking photos using the Pi camera module using the excellent raspistill command line utility provided by the Raspberry Pi Foundation. In it’s basic form the utility uses a set of default values. I wanted to experiment with the different settings available for EX (Exposure) and AWB (Auto White Balance) and see how they performed in different environments.

Trying different settings manually seemed like a lot of work so I decided to write a script that would take a sequence of photos using all available options. I could then quickly review the photos and see which ones looked best in a particular environment.

The script could be used whenever I needed to quickly check if tweaking the options was worth considering.

Raspberry Pi Camera Board – The Raspberry Pi Camera Module is a custom designed add-on for Raspberry Pi. It attaches to Raspberry Pi by way of one of the two small sockets on the board upper surface. This interface uses the dedicated CSI interface, which was designed especially for interfacing to cameras. The CSI bus is capable of extremely high data rates, and it exclusively carries pixel data.
