In desperation, I went to the harbour this afternoon to photograph our flock of Purple Sandpipers. The light (or lack of it) was depressing, but with the aid of a bit of white-balance adjustment and a fair dose of 'shopping, I got some half-decent images, but no sparkle from the sun.
The problem with the Purps is that they go there to roost at high tide so just sit there asleep with heads tucked under their wings. You just have to hang about until one moves!
All images were taken with a Canon EOS 1D Mk IV, F4 500mm IS II lens and 1.4 Mk III converter on a Gitzo tripod.
1/30th sec @F14, ISO 1600.
All other images 1/250th sec @ F5.6, ISO 1600.
