Set the virtual camera's sensitivity.
- To change the brightness of a rendering…of course we can adjust the intensity or exposure…of the lights.…We can also adjust the exposure on the camera,…to let in more or less light.…In the camera viewport on the viewport panel toolbar,…there's a button labeled camera attributes.…It's a camera with a little gear icon.…Click on camera attributes…and in the attribute editor,…let's close the camera attributes…and the film back sections…and open up the Arnold section.…
And here we've got the exposure value…to control how much light gets into the camera.…To see the results, let's open up the Arnold render view.…I've got focus on camera one viewport.…Go to Arnold render…and with the default exposure of zero…it looks a little bit dim.…If this was the only light I was going to use in the shot…then I would probably want to increase the exposure.…Click and drag on that slider…to open up the camera's virtual iris.…
And each whole number here, let's in twice as much light.…So if I set it to zero,…I get a pretty dim rendering.…
