Hello from another Duncan
There's something weird about your images here on LL.
I clicked through to your website they are MUCH better.
E.G. The first one looks like there is little shadow detail (already commented by others), but the same image on your website looks significantly better.
It may be something to do with that Flash plugin - check the colour space is set up for a web friendly sRGB when used to post link outside of your website; other than than that I don't know what to suggest!
I'm not a fan of Flash plugins as they take forever to load on my 1Meg broadband (I almost gave up on yours); I've got one on my website too, but at least the menu is not in flash, so people can navigate without waiting for Flash to load.
Some very nice images on your website from one of my favourite parts of the UK - I love the wild west coast of Scotland. I was on Canna for a fortnight in Jan and will be back in May for a week in Knoydart and a week on Eigg - Woo Hoo
