Undoubtedly its photoshop work:Reason 1: the subject and its reflection are always symmetric. In this case, you can see that its unusual and not 100% symmetric.Reason 2: the right wing of the subject is touching the left wing of the reflection. In the angle that this image is shot ie eye level, it is impossible for such a scenario.Reason 3: the reflection is way too clear. Reflections from water are always blurred and impossible to figure out the feathers.Reason 4: No gap between the subject and reflection. No matter how close the gull is to the water, there is always a gap between its subject and reflection unless the gull is in contact with water. If it were in contact then where are the water ripples ?Sad but true, this image has won this competition. Hopefully, those who are voting will vote for real photos and not photoshopped ones.
