Nikon’s ACTIVE D-Lighting

Nikon Coolpix P6000 Active D-Lighting Comparison

Now I’ve sorted out the difference between Active D-Lighting on the Nikon Coolpix P6000 camera (and other Nikon cameras) and the plain D-Lighting, I thought I would try a comparison of the former.

I took a picture using each setting: Low, Normal, High and Off. I thought the scene covered a wide range of tones from highlights to shadows.

Like yesterday’s comparison with post-processed D-Lighting (in camera) I made one file with the four pictures and their histograms from Lightroom.

I cannot see a major difference between the pictures: certainly not enough to warrant the extra processing time incurred on the slow camera. I think I could get comparable results with a Curves adjustment in Photoshop.

However, I am concerned about my experimental technique. I tried to ensure that neither Lightroom nor Photoshop processed the work the camera did. I wanted to show the pictures with only the camera’s processing. I am not sure if in the ‘printing’ process where I put each of the four images in a single JPEG file Lightroom tried to be helpful.

I have seen that when Lightroom imports files that I have exposure bracketed. It tries to adjust them to the same exposure, adding up to 4EV in the process. In this case ‘No! Please leave it alone!”
