View Full Version : How to show great distance in outer space?

I'm workin on a scene of the solar system here, and I have everything just about where I want it except for one thing: everything looks about 1/2 millimeter deep!

my shot in reality would prbly span a billion miles or so, but there's no feeling of great distance.

I thought maybe an asteroid belt or some kind of hazy space dust might do it.

I'm not going for Astronomical accuracy here; other elements in the illustration are primary. but I need to do a better job of showing what are truly enormous distances.

any suggestions?

Can you show us where you are at the moment?

Having the milky way in the background would help. Put the camera close to one of the planets to set scale.

Use a wide lens on the camera and keep its motion relatively slow.

A suggestion regarding huge scenes, by the way: Animate around the origin. If at all possible, keep the subject at origin and animate the world around it. You get horrible precision errors only a few dozen miles from origin.

Hey, thank you all for the responses...I'll post a pic of what I've got soon (still doing a test render)

this particular project is a still image (tho I'll prbly animate it down the road).

basically I have: planets from Mercury to Saturn, in order, but not in astronomically-correct relative size, and the distances are..well..heh..

you know how you must alter "reality" in a 3D illustration sometimes to suit the purpose.

I have a large poly surface with a home made star field to indicate "space," but no galaxies, no debris fields, no asteroids, no haze no nothin.

I can see how a putting a galaxy in there would help greatly.

but maybe haze and "dirt" would help, too..

I'll post as soon as render allows.

thanks again.

A couple other things that are involved in depth attenuation are a slight blur (but not depth of field) and desaturation - those are of course in-atmosphere effects, but they might help make it look more real to the viewer.

In regular still photography, it helps to think "foreground, midground, background". By placing something with a known scale or aspect ratio in the foreground, and using a wide-angle lens that gives the foreground object a bit of spherical aberration, you provide the viewer's eye with hints regarding the "vanishing point" in your composition, which sets the scale. Having something immense in the background (like a galaxy) can confirm the vanishing point.

So, having the planet in the foreground and galaxy in the background (as suggested by IZZE) might be your best bet. A model of a satellite, spaceship or probe in the foreground might also work, again using a wide angle lens so it's slightly distorted. I like to compose space scenes from the surface of a "moon" or "asteroid" to give the viewer some perspective.
