Basically it expands the dynamic range captured. It brightens the dark areas of an image while preserving the highlights. The higher the level of DRO you apply the brighter the shadow areas of an image are. It works similar to the HDR concept but it is more limited. I have some friends who are black or hispanic and have played with on them in white shirts and it does work if you expose for their face it will not blow the highlights in the shirt unless there is an extreme lighting condition. It does have an impact on white balance and you will need to manually correct this in Photshop or you can try test shots and adjust the whit balance manually. It DOES NOT work well if you shoot in raw as all it does is grossly underexpose the RAW file. DRO uses a gain type adjustment and not an actual shutter/aperture adjustment It can be fooled if you have a bright light in your image as it uses matrix metering regardless of the metering mode you choose and will attempt to retain the brightest part of your image which in some case may not be what you want which is why there are different levels on my camera. Not sure about the levels on the A100 as I have the A700. Practice turning it on and off, using on friends with different lighting conditions to see how it changes the images you are capturing. Since I only use it for snapshots of friends and family I can't give you too much more advice other than to play with it and see how it fits into your style.
