An interesting blog post with fantastic photos by Darren Jew (who I hadn't heard of before) Humpback Heat Runs: How to Photograph the Biggest Courtship Battle on Earth | Running Ponies, Scientific American Blog Network with a link to a video, which is actually a commercial for a certain camera manufacturer, whose products I have never used. It's a pity that the image quality of the video can't match the stills. Alan
Thanks for the link! Amazing work. Though my favourite photos are from this well-known video: (not just because I like pinnipeds).
