Ok, here is my problem (one of many!). When I create a scene I have trouble making things inside of the scene look "Life Size". Trees never have that "actual size" look. It's not just trees....It's everything!!!!! Here is an expample. See what I mean??? I am going nuts. Is there something that I can use as a guideline for real-world size?? Please help me oh mighty renderers!! Thanks for any info in advance! extrusiontek

Depth of field gives a very powerful illusion of scale. with no other clues to guide, the more DOF used, the smaller objects will appear. (I reckon the more blurred the forgeround, the closer it will appear and the more blurred the background, the future away it will appear.)

Well what you have to do is settle on a measurement for each unit in Bryce. I like to use for outdoor scenes 1 Bryce unit = 1 foot indoor 1 Bryce unit = 1 inch once you decide on a scale for a bryce unit then create all your objects to that scale. Usinf DOF and haze and some optical illusions you can "cheat" somewhat too.

other than what has been said already: If you mean materials? In the material editor you can scale the size of textures. Otherwise you will just have to develop an eye for this. ... don't rush it.

You can use several objects of different sizes in a scene like a small poser-figure in front of a huge building to give a sense of scale. You can also use haze to give the scene a sense of depth. You can, for instance, let the haze play with the mountain in the background to let it look realy huge (it seems to me that that is one of the things you are trying to accomplish) you should also let the background mountain get more blurred (or you should get the front less burry), otherwise the mountain looks like it is much closer to the camera and that results in the collums losing their size.

The point of view is also important. If you want that something in the foreground appears bigger than it is try to set the camera looking from bottom. ( Like the video of Kylie Minogue or Anastacha, they seem very high ;P)

vasquez is right, and if you try this at a human figure and you place the camera at a slight angle so that you look a bit to the side of the figure you get an even bigger effect, and you can let the figure look like he/she is really an important and powerfull person. This trick is often used in propaganda-video's like in WW2 and Houssein.

I think vasquez hit the nail on the head.
