This Common Loon was swimming by the edge of the forested shoreline, on opposite side of sun angle with no possibility for me to manoeuvre for better light angle. When it passed by a large area of dark shaded water I knew I may have something different to work with so I put on my "outside the box" thinking cap and created a series of in-camera backlit on black background images ("blacklit"). Most did not work out as envisioned, but this one stood out and was worth processing IMO.
Canon 7D + 500mm f/4 II + 1.4TC, manual exposure, evaluative metering, 1/1250s., f/7.1, ISO 400, natural light, handheld from paddle boat, cropped for comp after levelling the horizon (but wondering if it needs a tad more CCW rotation?), some smudged along the top cloned out, and an area near the tail end of the back darkened via burn tool.
