Lighting an Exterior Daylight Scene - Photographic Rendering with V-Ray for SketchUp - page 128

mination in a shot, we can set our aperture at F16 and then simply set our shut-
ter speed to be one over the film speed or the ISO setting being used. So if, for
instance, I am shooting using an ISO value of 100, my shutter speed should be
set at 1/100 th of a second. With an ISO of 200, this would be 1/200 th of a second,
and so on.
With the V-Ray option editor open then, let's perform the following steps:
1. Click to open up the Camera rollout.
2. Set the Shutter speed to a value of 200 , F-number (or F Stop) to 16 , and of
course Film speed (ISO) also to a value of 200 .
3. We can also set our camera's white balance control to match the earlier sug-
gested values for reference capture, so H 227, S 6, and V 255 it is.
Tip
It would be good to remember that no matter what setup values we use
here, we should always fully expect to have to revisit and tweak most if
not all of the camera settings once we start to approach the point of cre-
ating our final renders on the project.
Now we aren't quite finished with our exposure settings here, but before we can go
ahead and finalize them, we really need to set up the first of the light sources that we
will be using in this particular set of shots. Typically, this will mean setting up the key
light for the scene.
