I'm currently gearing up to produce a number of external rendered images in Revit.
Tests I've carried out are coming out too light.
Has anyone had similar problems and if so what did you do to overcome the issues?
Does anyone have reliable exposure settings?

Try adjusting the time of day--for exterior renderings, the sun/angle is key to good lighting. If your are too light, they may be getting bleached out by too much sunlight--try changeing time of day to a bit later in the afternoon or early evening.
Exposure controls and saturation can also help, but use these conservatively--it's always bets to get the lighting correct, render, and then fine-tune.
One other thing to check is the callibration of the monitor - uncallibrated or out of date callibration can cause images too appear to light or too dark.
The exposure controls works quite well for recovery of bleached out or over-dark areas. Some scenes present conditions in which it is near impossible to obtain a perfectly exposed render direct from the render (particularly part internal, or interiors with external views).
Another thing that is sometimes overlooked by people doing renders, is that there is often far more detail in the render output than is visible on the screen. Using the exposure controls can help to pull detail from shadows or bleached highlights that you think has been missed.
In this instance it wasn't desirable to correct the sun position in all instances so I adjusted a couple of the exposure values slightly, midtones to 0.8 and saturation to 1.2, not perfect - but good enough!
