Great Blue Heron: York County, Maine, USA, October 2023 — I think this is the last shot from my session with the Great Blue Heron in the Mousam river rapids that I will share for now. Fishing the rapids is a delicate balancing act, as many a fly-fisher who works this stretch of stream, can attest. OM Systems OM-1 with ED 100-400mm zoom at 472mm equivalent. Program mode with my custom birds and wildlife modifications. Processed in Pixelmator Pro. ISO 5000 @ f6.3 @ 1/640th.
