In this composite, the photo on the left, dubbed 'perfect shot', was taken by Scottish photographer Alan McFadyen; he spent an estimated 6 years, 4,200 hours, and 720,000 exposures trying to nail the perfect symmetrical shot of a kingfisher diving into its reflection. Whereas the photo on the right of a diving Common Tern was taken by me, spending about an hour by a pond in one windy afternoon when the sun was still high on the sky. Moral of the story: if you don't put in time, don't expect to get the result you hope for.
