I had been wanting to take a 24-hr timelapse of the tides for over a year now, ever since I began playing with the 24 hour technique last last summer. I had recently obtained the necessary battery gear and fisheye lens, and on December 2-3, 2017, I had the (almost) perfect conditions to take this timelapse. There were more clouds at night than I would have liked, but on the other hand, there was a supermoon falling across a weekend (early Sunday morning, technically). Not only were they some of the largest tides of the year, but I didn't have to be at work, so I could stand outside on Campus Point (Goleta, CA) for over a day babysitting the camera (occasionally wiping seawater off the lens)!

Of course I couldn't pitch a tent on the beach because it was on campus, so I will say that it wasn't fun to be out there, but I had periodic fast food deliveries from my roommate, and a lot of layers on at night. I biked out to the location Saturday afternoon, and the camera ran uninterrupted until sunset on Sunday.

One of the most perplexing things to me is the lunitidal offset in Santa Barbara. The highest tide follows the lunar meridian by about 8 hours. It seems like the tides are almost 90 degrees out of phase. I can only assume that's a local effect due to being at the mouth of the Santa Barbara Channel headed into the Pacific.

If anybody that's read this far into the description knows how to remove sand from the focus ring of a Lensbaby Circular Fisheye, please message me here or on reddit!

Anyways, enjoy the timelapse! I've also posted my equipment/settings below if any other photographers are curious! I know I've learned a lot by reading EXIFs...
