A Sunny Beach Day – Solution
With so much going on in the photo, you would be excused for missing the differences in the rock formation. The rock in the top photo has what looks like an advertisement posted on it, which is missing on the bottom photo.
The guy in the red shorts standing near the rock formation is also missing in the second photo. The third difference is located in the horizon on the left-hand side of both photos. One of the extensions forming the mountain range visible in the distance is missing from the top-most photo.
