i would change it to what looks right to you. i would say that you are trying to simulate nice photography. if you are unexperienced, you leave the camera in auto mode, and as you pan around, the camera automatically adjusts the exposure based on how much light is coming into the lens. if you are experienced, then you have a decent idea of the exposure settings you need, but you would adjust them per view.

....i am not sure that you can for physical correctness since our eye adjusts depending on the condition also. it makes it hard to say what is physically correct.

i would say that beauty and photographic correctness should be paired together.

In PhotoShop... File... Open As... select Camera Raw, and then locate your TIF file. It gives you a lot of the settings that Adobe Aperture has. Pretty sweet.

Yes, hard drive space is cheap. We have about 200 people in our office, the majority on Revit, and several people rendering. Hard Drive space seems to go really fast, and I often have a couple of gigs of undeleted EXR's on the server, so I was trying to move away from them.
