rob its not a case of looking through old pics for settings as i have virtually none of b.i.f with this camera i like ..as i said its not just me the concensus is coming in not to use matrix though so thats one part settled .


Doesn't matter what camera you have used the exposure on a given day with that lens setup should be a good starting point.


one thing puzzles me if your taking a manual reading of the sky it will surely meter for that ,yes/no


Never said take meter reading of sky, You need an ambient light reading, either use a traditional incident light metre or take a reading off grass, your hand or maybe a grey board.



.you will then still need to dial in a positive exposure compensation for when a bird flies through that sky yes/no.


With an incident light reading, NO. With Manual exposure you don't need to add compensation, THAT is the point.



it will STILL be guesswork on how much positive compensation to dial in yes/no



YES, but when you get the hang of it it will be far more controllable and predictable. Using TTL metering with a tiny object against a bright sky is no more than a lottery, prone to error, the odds are against you.


so unless my thought process is entirely wrong its still pure guesswork and i'm back to square one :banghead::banghead:


In my opinion you need to go back to basics. The selectivity of the metering system isn't intelligent/fast enough to cope with a tiny dark (unlit) object (bird) against a bright sky. The metre reading you need to expose the bird correctly will be very close to the exposure you need for somebody's face 6 feet away in the same direction as your subject. Try it...
