Judith and others,

Just another point on choosing a camera. It should be able to accept filters. I find a polarising filter invaluable for reducing the background reflection off water when photographing waders and seabirds afloat. The trick is to frame the image, half press the shutter button and rotate the filter to get the best effect. If you don't do this the automatic gain control on the camera compensates and brightens the image in the electronic viewfinder or on the screen, making it hard to decide when the polarising effect is at its maximum. Then release the button and take the photo as usual. If I get time over this weekend I will post a link to some "with and without" images to show the difference
