In my understanding ADL compresses the dynamic range of the highlights on the nikon cameras. I normally leave it on at normal setting and it is a part of my work flow. Would there be an advantage to leaving it off. Thanks!

Since I always shot raw, I left ADL off on my Nikons.... ADL is one of those settings that only affects JPG's processed either in camera or by Nikon software.

I also shoot in raw, but if processed in nikons NX 2, the settings are applied to the mix when exporting as a jpeg, correct?

Yes, the Nikon software detects the settings like ADL and applies them to the raw.

I was using Apple Aperture when I shot with Nikon, then moved onto Lightroom - they did not read the Nikon specific settings, so for me they were useless.

I also like some nikon custom picture style presets. If then exported from NX2 as tiff for further editing in my favorite app. Am I missing something, in my reasoning, there are so many ways to do this.

Actually ADL does and does not alter raw files depending on how you have the camera set. There are setting combinations in which it will reduce exposure and reducing exposure is a real impact for the raw file.

Interesting, I never ran into those combinations as I stopped using ADL early on.

It affects only the camera’s JPEG.

It does not alter the ISO or exposure regardless of any auto setting so it does not change the raw file.

That is incorrect. It works exactly as I said it works. It does or does not alter exposure and subsequently the raw file depending on how the camera is set. Here's the proof. The camera set to A priority so the camera set's the shutter speed. Meter is set to matrix. Two photos taken moments apart with the only change to turn ADL on (ex-high) for the second shot. The camera changed the exposure by changing the shutter speed and the raw files are different showing the exposure change.

You example shows an exactly one stop change in exposure.

ADL is not simply turned on and off. It has several different levels depending on the Nikon model. The Df offers off, low, normal, high, extra high 1 and extra high 2. There is no apparent adjustment to auto exposure for the first ADL level but the exposure is decreased by about 1/3 stop for each level after that. This compensates for the additional brightness applied to the camera's JPEG by the different levels. The effect is a decrease in apparent contrast in the JPEG while holding the mid-tones constant. The D610 has only four levels of ADL.

You can also use ADL with full manual exposure (with manual ISO). And you can apply different levels of ADL after the fact in the camera to a single raw exposure.

Sony has a different name for it and handles the levels in a similar manner.

Fuji does something altogether different.

Yes, and so the key point: ADL can alter exposure which does change the subsequent raw file.

But it doesn’t change the shape of the raw histogram. It just moves it to the left the same way that EC -x would.

The purpose of ADL is to change the contrast in the JPEG assuming you don’t want to bother with the raw file or that you might want to apply a separate EC +/-n.

If you shoot raw ADL serves no purpose.

It does apply a tag to the RAW (.NEF) file. When that RAW file is opened in Nikon software - Capture NX-D, View NX-i it will apply in-camera settings to .jpeg files.

It also gives you a preview of what you might be able to do with the shadows on your computer. But the preview on the camera’s LCD is too small to make that very helpful, especially out of doors.

Huh! meaningless. In fact nonsensical.
