Still in Arnside

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.

High Water


Ullswater 4, originally uploaded by Bay Photographic.

Ullswater.
Not quite within the Morecambe Bay area, but if the water in the lake rises much more it may well join up with Windermere and form a new sea loch with its entrance near Grange. In some ways an appealing idea, but with Arnside Knott a small isolated island and the nearest harbour halfway up Ingleborough, one that is likely to be more popular with boatbuilders than landowners.
I don't know if climate change is responsible for the water level in the lake, but I am old and cynical enough to think that giving up my Land Rover for a Toyota Prius isn't going to do much to resolve the issue of global warming. Is it an unavoidable historical cycle or did my participation in an irresponsible societal attitude towards emissions bring it about?
In any event, is it as pressing as the problems of Aids, the easy availability of weapons, creating sustainable economic growth, and providing a clean water supply.

In Basingstoke as well as Burundi.

The photo above, shot on an environmentally friendly Fuji S2 pro, using a recycled memory card, was three RAW images, processed in Photomatix. The three reflections under the silver birch were more than the software could reasonably be expected to resolve into one, but it would have helped if the (rechargeable) batteries in my camera hadn't chosen to fail just as the sun came out on an otherwise dull day.

I had a spare set, but by the time they were in place, the moment, as they say in Kyoto, had passed.
