RFI- camera gift

["Roger Giller" <>]

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
Roger.
