Depth Of Field

V-Ray V-Ray for 3ds Max Issues
1

Hello,

I trying to work with a vray camera and the depth of field, but i don’t see the effect.

I don’t understand what “aperture” “center bias” “focal dist” work. So if someone can explain me the correspondance between these options and the camera…

thanks

Lele has a script that will focus your v-ray camera to an object. I have never tried it, but everything else he has done has been wonderful.

To have the DOF effect you need to check On the Depth-of-field checkbox (Sampling rollout). Blades (Bokeh effect) is also part of the DOF effect. The effect is strongly seen when the camera is very close to some object, just like doing a macro photo. So to have a strong DOF effect, the camera aperture has to be “open” - small f-number (f-stop) value. That would lead to a very burnt/bright image, so to preserve the same illuminosity over the whole image), the shutter speed has to be quick. And at last but not at least the focus distance will determine which part of the field will be actually on focus. To get the focus near, you would need a small value and reverse - higher value for far focus.
Exposure: on, f-number: 1.0, Shutter Speed (s^-1): 4000.0, ISO: 200.0, Vignetting: on
