[QUOTE="Horoscope Fish, post: 503661, member: 13090"] We can certainly make it relevant! :D Active D Lighting is applied to JPG's only, or I suppose if you use Nikon's post-processing software (NX-D, et al) the effect can be applied to RAW files. I'm a little unclear on the details of that since, 1. I shoot RAW exclusively and, 2. I don't use Nikon's post processing software; not that there's anything wrong with it. Fact is, I don't like ADL and that's because in my limited experience with it, I saw it introduce a lot of noise in the shadows; the more strongly it was applied, the more noise I saw in the shadows. Used sparingly, I guess it could help but in my estimation, and this is just me talking here, ADL is solution in search of a problem. If you've decided you want to control your highlights, shadows and midtones, shoot RAW and go nuts; and I say that without taking anything away from those that shoot JPG. I like JPG's just fine. But we also have to be honest and the simple fact is, you gain a huge degree of control over your exposure when you shoot RAW and that's why most of us turn to it.
