| Dec 30, 2017 at 20:54 | comment | added | Alchimista | Sorry too insist . Perhaps your question has fully to do with photography optics. If I take a photo with a smartphone or a cheap compact camera I get something like in your picture. We perceive the moon much larger than its angular size independent of its position in the sky. And that is amplified more down to horizon the Moon is. Have a look at Stellarium, a free package. | |

| Dec 29, 2017 at 23:32 | comment | added | kinkersnick | All those distances are in km, I wrote ‘m’ because I was translating them into meters (for 1000:1 scale), nothing to do with miles. | |
| Dec 29, 2017 at 22:41 | comment | added | Dr Chuck | You have the Earth moon distance in km, not miles. So it’s closer and so would be bigger - but still small. | |
| Dec 29, 2017 at 19:21 | comment | added | Alchimista | Let me add that even well known astronomical programs have a setting option called "realistic moon" to force the moon look bigger. | |
| Dec 29, 2017 at 19:17 | comment | added | Alchimista | Moon paradox . Somehow our brain interprets the Moon as larger than really it is . Paradoxically rendering a more realistic view. You can easily Google that. | |
| Dec 29, 2017 at 17:16 | comment | added | kinkersnick | OK, makes sense. It's a field of view thing. I've tried re-creating the scene in three different pieces of software and it's not consistent, because it comes down to the settings of the virtual camera. I'm trying to create this for VR in Unreal Engine, where you can't really mess with the FOV, so I may have to take some artistic license adjusting values to make the result look 'correct'. Thanks for all the suggestions everyone! | |
| Dec 29, 2017 at 17:14 | comment | added | AtmosphericPrisonEscape | Take @barrycarter's comment and take into account which field of view in degrees your program is simulating. If you'd zoom all the sky onto one piece of paper, then the moon would look small indeed as well. | |
| Dec 29, 2017 at 16:19 | comment | added | user21 | The moon (and the similarly sized sun) really are surprisingly tiny-- you can cover it with a dime held at arm's length. They both have a diameter of about 0.5 degrees, and the human field of vision is roughly 72 degrees (source: Commodore Sky Travel), so expect the moon to cover about 1/144th the width of the image or about 5-6 pixels for a pixel width of 800. mathematica.stackexchange.com/questions/153600/… is vaguely related. nikonians.org/reviews/fov-tables also suggests 24mm has a largeish field of view. | |
| Dec 29, 2017 at 16:00 | comment | added | kinkersnick | I just tried changing the dimensions to the actual 1:1 dimensions of the Earth and Moon, and it looks exactly the same, so I don't think it's anything to do with the receptor of the virtual camera. | |
| Dec 29, 2017 at 15:27 | comment | added | J. Chomel | Maybe receptor needs to be 1000 times smaller too? | |
| Dec 29, 2017 at 15:10 | comment | added | kinkersnick | I assume you mean as a reference? I plan to if I can tonight! Unfortunately, it's very cloudy here at the moment. But I feel like I must be doing something wrong here... | |
