I had a vague idea that if you took a sequence of pictures there was some way of joining them up, so without much idea what I was doing took a set of the harbour on my Olympus C5050Z. Back home I found that PixAround software was free and a couple of quick experiments showed it did a reasonable job. Bit of cloning to remove boats and their wash that showed up multiple times in the different frames and Bob's your uncle!
I just revived my Flickr account, triggered mainly by the big increase in storage allowed and am gathering my panoramas there
