after rendering all white

here is my very first test with Vray final 1.5



rendered in medium mode (960*720 pixels)
rendertime : 1m18s with 2 monocore Xeons 3.2Ghz.

i'm subburb

i'm a physical settings lover..
So i always use VrayPhysical cam, sky and sun.
Settings very standard
sky and sun at default values (1.0 intensity)

my exterior daylight settings:
camera :
f-number 16
iso 100
shutter speed 100

if you're not working in gamma 2.2, then try f-number around 8

exactly the same settings on my minolta dimage on bright daily exterior scene

for interiors, low down shutter speed, raise iso (i.e 200 or 400 for darker scene), and lower f-number to catch even more light.
Be careful, f-stop plays a important role in DOF.

Best regards.

You're welcome.
