Not to be a spoilsport, but... photo? That's just a bit of digital art,
isn't it? A fantasy world with a giant moon, a distant sun, and an unknown sea.
Pretty, yes. But fantasy.
Be thankful the Moon (the real Earth's moon) is only half a degree wide in
our skies. If it were close enough to appear even two degrees wide, the ocean
tides would rise and fall with an average range of about 200 feet. The
tide-generating acceleration is proportional to the mean density of the
tide-producing object and also proportional to that object's apparent angular diameter
cubed (2 degrees is 4x bigger, so tides 64x larger in range).
