Hi guys.
I tried to model simple room ( my offce), actually 4mx4m and 3m high. I modeled this as a simple box im 3dmax in centimeters. As far I understood, export function can this recalculate in the meters. So than after I configured physical sky, location Prague, timedate= today. ISO=200.
I've got 2 nice large windows there. I've been really surprised with very dark render. Do I need to setup some additional lights??? I thought it should be really very simple with maxwell.
Thank you for your support.

you will need to have a iso of 400 for dark interiors and/ or more lights on the inside of the room. the problem is our eyes adjust to rooms better than cameras. if you took a photo of a room in the day time witht he same settings you have in maxwell then im sure it would also be darker than you thought. be anal and treat it as if you where taking a photo of a real room.

1. Hmm, my office is definitelly NOT a dark room.
2. To switch more lights on??? NO. I don't switch the lights on through the day in the reality.
3. About ISO400, you are right, usually one should take interior pictures with higher ISO.
VERY GOOD IDEA TO TRY TO TAKE A PICTURE AT FIRST.
My point guys is, I just set up 5 minutes scene and would like to see real result. It is very simple scene, rectangular room with 2 windows.
Thank you for your support, i'll try it and give you a feedback.

Hmmm, but why do we render, if we need to take a picture at first ....

your room is not a dark room as seen by YOUR eyes this is why i said the camera will not see as much as your eyes do. so yes your room might not need lights on during the day. but to get a bright photo of said room you will need to adjust the camera settings to suit and/ or turn on some lights

anyhoo never mind adjust the camera and all should be well (maybe)
final note do you want "real" camera photo render or "real" what the eye sees render because this has been brought up a lot here

Ok guys, I tested it and it works fine as you said. I have to read something about taking pictures and take some pictures at first to test it all.
Thank you for your support.

Also, are you using ags or glass material for your windows? Trying to light a room with caustics is next to impossible.

I always wonder why try to replicate what a photo camara captures instead of replicate what the eye sees? I wouldn't make things much more "easy than taking a picture"

I guess the human eye is 1000 times more advanced than any camera, so it might be quite a challenge to create a program that works like you want...

"What settings did you use for the number of rods and cones?"
