The thing that makes this an exceptional shot is the almost mirror like reflection from the windows - leading one to believe that it might be some new form of patterned tinting. We can see the reflection in the paintwork, and that may be a clue that it is actually a reflection. But without being told as much, the illusion is convincing.
But actually… I am always really curious to try to figure out WHY exactly an image (mine or someone else’s) makes an inpact. Trying to find words to express that has (for me personally) alwys resulted in a deeper understanding. That is why I am pushing a bit.
Beautiful family memories shots of what must have been a fun day. The line of people from the side and the matching line of dolphins gives pleasure with the repetition. The freezing of the action, water drops and dolphon bodies and expressions lets the viewer enjoy details that would otherwise be missed. One of the pleasures of photography. The sequence lets us follow the curve of the dive. Actually, I think we have at least two dives here that have been arranged in sequence.
Much as I think the photos are fine, I don't like animal trained acts however.
