Hope the high tide pictures came out well.  I am sure that they are good.
Love the swirl of the esturary in the first image.

The shapes and forms of the channels are amazing.

I got about 3½ hours of video of the tidal flow, compressed into about 27 seconds!  I have stretched it to about a minute and a half and posted it on YouTube.  The compression is crap, it's WAY better with the original in iMovie.  I may try re-processing the files.

For what  it's worth here is my first attempt of a time-lapse tidal flow, started at about 06:30 am BST to about 11:00 am BST.  High tide was about noon.

I slipped up and didn't charge the D800 battery so when I realised after about 30 minutes, I swapped it out for Eric's Battery.  That did 4 hours of time-lapse and ran out, I had set the D800 to record until noon, high tide time.  I have a 'cheap' plastic motor drive second battery holder, I believe that will allow me to use both batteries to power the D800, effectively doubling the recording time.  Also, I made an exposure every 15 seconds,  I plan to increase that to every 5 seconds, that should produce a smoother video.

I am very disappointed with the poor quality from the YouTube video, I may have settings wrong, I always struggle with video, it's a pretty specialised area.  I very rarely do video so most of the  terminology is gibberish to me.  Anyway, enough excuses, lets see if it works...



BTW, many thanks to Chris, who has made this possible.  I have some horse pix of my own I will post once I have this working.
