Tweaking exposure
As we close in on finalizing our exterior lighting setup, (at least for the time being), we
have reached the point where we may want to consider revisiting the exposure set-
tings that we been working with up to this point and see if there are any tweaks to be
made that could perhaps benefit the final render in some way.
We can ask probing questions, such as, are the values being used perhaps making
things a little too bright or overexposed? Do we want to push the hotspots in the image
a little more, giving the suggestion that we are looking at a setting found in an ex-
tremely hot climate?
Whatever our initial answers to these questions, it would probably be a good idea at
this point in time to go ahead and render out a series of shots, one from each of the
available camera views so that we can make a thorough evaluation of the scenes cur-
rent lighting.
In fact once we have those renders, one exercise we may want to try would be to take
our images into an image editing application such as Photoshop and make use of
the histogram function that can generally be found there. This can be used to visually
evaluate the overall spread of tones in the scene and also experiment with brighter
and darker exposures
