Here are the images commenting on AD-L with the D7000 (from 'that other forum')
EXIF data doesn't show. ISO 100, f11 at 1/100th on first shot, 1/200th on the shot with AD_L enabled. ISO was 140.
This was obviously too far for a flash to reach the distant end of the railway car. The bright and shadow areas would require another technique to even out the dynamic range.
That kind of dynamic range and spiffy detail in the AD-L shot were commonplace in the '30 & '40s when news cameramen carried a 4x5" graflex press camera. Astonishing dynamic range and crisp, crisp resolution. You could see it often in Life and Look magazines during the WW-II era.
