interior lighting with sun and sky only

[sdds]

I'm playing around with lighting interiors for animation with just sun and sky, physical cam. Would be interested in how others achieve a balance of enough light without blowout.

You can go with the Reinhard or Exponential color mapping to avoid this.

(The blowout is kinda natural.. take a real world pic. and it will happen.)

these tut vids are very helpful when it comes to vray sun, sky, physical cam.

indeed, main focus is exterior but principles apply throughout

 

hope it helps

thanks deanomagino, I've been looking for an explanation on that technique. Still dont know exactly how to apply it. set output rgb level for every materiel, is there a way to globally do this?

here are some of lele srcipts i havent tried all of them but you may find what your looking for.

there is a script written by Lele, it isn't on scriptspot.com, but there is no need for it anymore, as the newer versions of vray, 1.5 sp2 and more do not have the same issues as the version presented in that tutorial.

I use exactly that method, except for the part where you have to darken the materials, as i'm quite happy vith the results. sometimes i use reinhard instead of linear (in color mapping) to control the burn.

Hi

 

I'm working on a couple of interiors at the moment using the same technique.

 

Like others have said, control the 'blow out' with the f-stop / iso etc + use reinhard colour mapping with a burn value of approx 0.2.

 

I'm assuming you are using gamma 2.2 settings ?

 

It really depends where you are postioning your sun....this makes a huge difference especially if you have large window openings.

 

Good luck

[andstef]

yes i use gamma 2.2

 

of course the position of the sun is affecting the scene, it's like in reality when you have to take a picture in a room with windows facing north where you need a higher iso, larger aperture, etc, and in a room with windows facing south with sun shining through where you can have lower iso values etc and even a different white balance.
