Right. Lots of piccies, with a little commentary. This one is straightforward:
This is the first time I have 'doctored' a picture (other than simply cut out an area) - it was too dark, so I've started to explore some of the 'lightening' features on Irfanview.
This is evidence of the high tide this lunchtime - the highest that I've seen it since being on Mersea.
This is my own footprint, from two days ago...
And these are some close ups, as I was experimenting with the zoom lens.
