As a new D3100 owner I have been trying to read all I can about my new camera.
I'm wondering if the D3100 Active D-Lighting is really useful?
To date, the reviews I have read have not really answered this question.
For example "Active D-Lighting is Nikon's dynamic range expansion option, designed for use when faced with high contrast scenes to maintain shadow detail without blowing the highlights. It's a feature shared by all of Nikon's current DSLRs, but unlike models higher up the product line, the D3100 only has two settings - on or off. The effect of Active D-Lighting differs depending on the scene, so this test, performed using our 13-stop wedge, isn't necessarily an accurate indication of 'typical' performance. It does clearly show, however, the way in which ADL is designed to work, extending the visible dynamic range by lifting shadow areas and darkening highlights, to get the most detail out of these areas in a single exposure."http://www.dpreview.com/reviews/nikond3100/12
I hope someone has done some real world tests!
