Time-lapse video is fairly straightforward simply calling for lots of images to stack together but to successfully make a nice time-lapse which covers the extremes of exposure from true dark night to full daylight isn't that easy because simply putting the camera on fully auto will give unpredictable and unacceptable results. The changes from dark night sky to full daylight need a more subtle approach.
I have discovered software which can control the cameras exposure from the computer. You can set the parameters and the computer (or tablet or 'phone) calculated the exposure adjustments needed to maintain a smooth transition from dark to light over a large dynamic range of exposures. The computer sets the aperture, shutter and ISO according to your instructions.
The software is part of LRTimelapse.

Which as the name suggests, works with Adobe Lightroom to create time-lapse video, right through to the final rendering.
I am hoping to try it out tomorrow with the intention of using it early on Tuesday morning when I think the tides, the Moon and the weather will all combine to provide a working stage for me to capture the dawn.
I would like to create a motorised head to mount the camera on so I could slowly pan the camera as dawn approaches but first things first... I need to get the exposure technique right first.
