Hi, i am slowly getting to grips with my 7d and BIF ,however today i photographed a kestrel hovering 30/40 ft away on my 100-400 ,the conditions were cloudy(grey) and i had my settings on C1 set up for BIF .....Normaly that would be fine(good sunny day) but i managed to just get a dark bird against a light background now i believe i should be using EV compensation and wanted to know would i loose detail doing this or would trying to recover in lightroom be a option or would non of these options give me full details or a good result......Or just accept that you are not going to get good results from a grey sky and a dark bird.
 
Yes, if you had used a bit of EV compensation (eg +1 or +2) you would have a correctly exposed bird, but the grey sky would be likely to be blown. Not really much you can do easily in those circumstance - a large are of light sky with a comparatively small dark bird, though in PP, with work, you could insert a different more interesting sky.

You could recover some of the detail from the photos you have in PP, but as the bird is under exposed, trying to pull some detail out of it is likely to increase noise.

You could have used AEB and combined a number of shots. Normally combining shots that include movement is not a good thing but some software will handle the ghosting effects of movement, but I have not tried it with birds wings.

Depends what your C1 settings are Den, dark bird & brighter sky could be anything around the +2 EV depending on the metering mode.
 
That's a great link(read) i realy wish i had now used the Ev mode a lot more.....as far as i can see it now EV is a addition to the triangle , if that makes sense.
 
A reasonable place to start is to meter the ground (grass is good) and use those settings in manual ;)

Yar, these conditions are ideal for manual.

Basically you should know (or have now learned) that the metering system does not understand what you are trying to do when you point it at a large expanse of bright sky but want to expose for the small bird in it.

Metering off the grass/concrete/your palm is the best way to go.
