 <color red>Remember:</color> if you don't set the pins to low after shooting, it's the same as keeping your finger on the shutter button, the camera will just stay in shooting mode (but the shutter will close) and you won't see your preview image or be able to take any more shots. <color red>Remember:</color> if you don't set the pins to low after shooting, it's the same as keeping your finger on the shutter button, the camera will just stay in shooting mode (but the shutter will close) and you won't see your preview image or be able to take any more shots.

 We have used a simple program to fire the camera, but more useful would be to have some options. The following code prompts the user for two inputs, the first input is the number of desired photos to be taken, the second is the delay between photos. We have used a simple program to fire the camera, but more useful would be to have some options.

 This code will form the start of my Raspberry Pi Intervalometer. This will be a great tool for static time lapse photography. Once this is done then I can move on to my camera slider project. However the actual slide rails for this will I think take me some time. This code will form the start of my Raspberry Pi Intervalometer. This will be a great tool for static time lapse photography.
