| Jun 18, 2015 at 21:46 | comment | added | Sarmes | @Peltio ok i am speaking about cases where one is not that far away, like in the example movie at around 11 minutes, you could see somebody walking on the beach. Your example is nice, but its time lapsed, and even for that it is time lapsed, the details and waves at eg around 3:30 look more like it was in slowmotion, then fast forward. I expect very noisy details in a time lapse, not a frozen like water surface. But it appears i am the only one for who this is surprising. | |
| Jun 17, 2015 at 20:28 | comment | added | Peltio | But you are too far away to see that sort of detail. You are only seeing the 'big picture': ocean waves with several meters of wavelength. Ever flown over a lake? It's been a while but if I remember correctly they look like mirrors. (Great lakes do not apply :-) ) First video - and maybe not the best: youtube.com/watch?v=_enqzMqsnMg | |

| Jun 17, 2015 at 17:18 | comment | added | Sarmes | @Peltio I understand that when things are far away they appear to move more slow. But im surprised that if many things like waves are far away their relative velocities with respect to each other are also small, while when you are close those waves are interfering all the time. | |
| Jun 17, 2015 at 16:54 | comment | added | Sarmes | Is it really only that? for example in youtube.com/watch?v=GUDV7oVm76k at around 10:45, its like the places where the waves are braking are completely frozen. Whereas normaly they "break" then you have to wait a bit, and then the next one breaks. Maybe its an illusion but i like to understand why i and the video camera see it that way? | |

| Jun 17, 2015 at 16:05 | comment | added | dmckee --- ex-moderator kitten | This is a bit of a hobby horse of mine, because few people seem to be aware of just how heavily edited, filled in, patched together, and outright wrong what they "see" really is. Your eyes lie to you more egregiously than any of your other senses. Treat their reports with considered skepticism. | |
| Jun 17, 2015 at 16:03 | comment | added | dmckee --- ex-moderator kitten | This isn't really a physics question at all. It's about the human perception system---how you deduce information about movement from visual input. When far from land, you have no stationary references against which to judge the motion of the wave crests, so your visual interpretation system punts. | |
