Well the title says it all - I have tried battling with grey skies and nearly every time I come away with drab and empty looking photos. Being that I live in the UK this sort of weather is far from uncommon and so rather than just not shoot on such days I would far rather learn to deal with such lighting. Add to that the fact that on such days the diffused light means that highlights are not a worry - something that on bright sunny days is a constant battle against. I know that lighting is everything and that one cannot get "perfection" without the "correct" light, but there must be tricks and ways of dealing with such lighting without changing your subject matter. I don't intend to move wildlife/zoo shooting indoors - my landlord would have fit .
