An interior with bright views out of the windows has a very high contrast.
Taking several photos (underexposed photos for the windows, overexposed photos for the interior) will allow you to see both the interior of the room and what is outside the window.
The basic technique for taking the exposures is detailed below. It assumes your camera has an AEB (Automatic Exposure Bracketing) function that allows to take at least 3 photos in 2 EV steps or 5 photos in 1 EV step.
A tripod isn't absolutely necessary with the basic technique, but is still highly recommended.
The next page details the advanced technique. Use the advanced technique when you need to ensure that all details in the view are rendered, or if your camera doesn't support AEB with 3 photos spaced by 2 EV (or 5 spaced by 1 EV).
If you are not familiar with the AEB functionality of your camera, consult your camera's manual or this webpage.
You now have bracketed photos, ready to load into Photomatix.
If you need to ensure that all details in the view are rendered while the interior remains bright, then use the advanced technique (the main difference with the basic technique are in steps 4 to 6 listed above).
