I have a problem I've been thinking on for some time.
I have mounted a Canon Eos 30D on a pan & tilt system for panorama footage.
I input degrees and time and such and the Arduino handles the rest.
The rig moves a certain degree before stopping and triggering the camera to take a photo.
This it repeats as long as I setup with the intention of sunrise to sunset.
Now the problem is that I must have automatic shutter speed on in the camera, because it has to be able to shoot in unknown light conditions during the time. This means between milliseconds to 30 seconds max.
Since the connection to the camera is, let's just say it, primitive (stereo-jack with only shutter and focus), the Arduino cannot know which shutter speed my camera has chosen. And I want to know it, roughly at least (to trim down wait time between photo and moving servos).
So my question is if anyone in here has a creative solution to this problem?
For example: My current idea is to attach a light sensor to the display on the back of the camera and, since it blackens during photo, just check when it gets back online. But that has its own problems.
Is there anyone with a better idea? Or more fun?
