This could have been an exposure nightmare, but using fill-flash in this situation helped retain details in the blacks as well as keeping some detail in the snow. Not your typical "RWB on a cattail singing and flashing epaulettes" photograph, but that is one reason I like it:).
Canon Rebel XT +100-400L @400mm, 1/1250s, f/7.1, ISO 400, no EC, fill-flash @ -0.7 FEC, handheld.
Great pose Daniel with the raised foot just adding that hint of action. Good work on keeping detail in blacks and whites. (As you say, an exposure nightmare)!!
What is the RWB?
