<how about a spotmeter and preparation - set up a grey 'spot' out of frame for exposure reference - maybe just a jam jar lid painted grey, white whatever poked onto a metal stake and arranged toward the hide that you can take a current reading from?> Karl Not a bad thought either for certain situations. With a long pointing at a set up I'm not going to want to have to keep swinging it out of shot so it's a separate spot meter - 1 degree or better probably. But absolute perfection would be an "ambient exposure mode" setting on the camera that when selected took it's reading from the remote meter automatically. That way you wouldn't have the iterative process every time a cloud passed ... TTL is as good as it can be OK most of the time Crap for black cats in coal mines Crap for swans in a snow storm TOTALLY rubbish for blackbirds sitting on a twig against a bright white sky.
