hi guys,
At the moment i have some problems getting the dimensions for building a dojo. I need a camera (value setting) that should represent the human eye, so to say, the camera should show the world just as an human eye.
I know I could change the room to fit the sight, but in 3dmax, the room does always look eighter too big or too small, in my case.

So my question to you is, what are the correct settings for the camera (FOV and lens in mm) to imitate the view of an human?

If I'm correct, a 35mm lens has the same ammount of perspective as a human eye. Though have in mind that the effect of perspective on the object also depends on distance between it and the eye. The closer you are the, the more intence the perspective. Having that in mind might be useful for your project.
If I understand your plan correctly and that is that you want to model the dojo from live reference in the perspective view (not sure wether I got it really), then you don't really need to know the lense, you need the distance, since a function of the lense is to marely take a certain ammount of FOV to fit onto a 2 surface. shooting an object in 35mm and 50mm fromt he same distance won't change the perspective. Only the object will appear to take up more of the screen in 50mm.

There's also some stuff about the human vision beeing a 1x1.618 (golden number right there) elipse. But this is more for compositional purposes, I don't think you need this.

And btw, next time Please post in the correct cathegory. Non-software-specific questions about how to do this'n'that and what works how go in the general CG discussion. Thank you.
