Still in Arnside

Arnside, Stone Jetty Bench, originally uploaded by Bay Photographic.

Freezing action in a single frame is usually achieved by setting the shooting menu to shutter priority and using as fast a shutter speed as the available light and the lens will allow. However, when I take bracketed shots for later processing as an HDR there is the possibility that movement may be recorded across the three (or occasionally five) frames required despite being frozen in each individual picture. The reflection under the silver birch in the post below this is an example.
This is a particular difficulty around water, and since many if not most of my photographs have water in them, is a particular difficulty for me. Or to be more exact, for my copy of Photomatix. There is a menu which includes an option for 'Attempt to Reduce Ghosting Artefacts', but there is a price to be paid for selecting this. To be honest I'm not really sure why, but it reduces the overall quality of the image and changes the tonal range.
The photograph above has no such issues however. The water is millpond still, there are no people walking through the frame, no cars driving along the promenade and no trees waving in the breeze. Even the two men talking outside the chemist kept obligingly still. So all three frames are monozygotically identical.
Except for a single seagull, which was photographed three times in different parts of the frame, thereby giving the impression of three seagulls flying over the promenade on Saturday morning when there was only one.
So I am identifying the other two as false readings.
I think it might be best to declare every contribution at the outset, rather than have to blame poor accounting later on.
