I don't know what did it, but my guess would be that it is a digital artifact of post processing.

While I do agree that it is only partly to do with the sensor the D800e has and part to do with the software used. To me though I am continually astounded by the performance of the two in conjunction with each other. I have not tried the CC side of Adobe and am beginning to feel like I am openly resisting it, for some reason.
I know I have never been able to gain this type of detail out of any other combination I have used before.

No they are not anywhere near quality macro shots the amount of detail that is able to be gained from the original image is astounding, to me at least. To see the facets of the eye from almost 20" away blows me away. I was more making a reference to CS and CC than the camera itself. But thanks for the critique.

I used to get a white outline on some areas of an image on over cropped and enlarged images. It's one of the reasons I moved to the d800e where it is seldom seen. At times the color of an adjacent object would seem to bleed into the edge of a neighboring object. It seemed that as the image was enlarged there weren't enough pixels to cover the contrasting lines separating the objects. That's what I thought was a kind of chromatic aberration as it would occur in strong side lighting situations. But I defer to your view on this due to my own lack of technical experience.

I think chromatic aberration would not result in a white line. Sort of by definition, because chromatic aberration is the splitting of white light to the component colors.

I think perhaps you are seeing a demonstration of what DxO calls "perceptual megapixels" (or something like that). The idea is that image resolution is the product of both the lens and the sensor. The sensor Mp sets the theoretical maximum resolution and the lens (every lens) degrades it. A very high resolution sensor with a so-so lens may give more net resolution that a very modest sensor with a great lens. Or it might not. It a case by case situation. Play around with the DxO lens comparison webpage and you can see this.
In the case of the D800 there is also the EV range which is very good. That most likely relates to what you see in the shadows.

I think a white outline in almost any situation would be a digital artifact. Optically, to create white out of colors is quite difficult, to get the exact colors of the rainbow to merge. Monitor manufacturers spend a lot of energy making sure the RGB pixels can produce a clean white. Chromatic aberration does not need the crop/enlarging actions, I think it is optical.
Some of what you are talking about is a resolution limit, where the colors of adjacent items blend together because the lens/sensor combo does not have the resolution to keep them separate.

Is that essentially the same as running out of pixels to foil the space between contrasting parts of the image?[pquote=amehta]I think a white outline in almost any situation would be a digital artifact.

I was referring to the white line around the edge of entire upper portion of the main doorway arch. Some sort of artifact. It is not anything natural.
I see it on the first shot. It's like some kind of sharpening artifact. :?:

I think it would be a combination of running out of pixels and having optical issues which would cause the chromatic aberration.

I've seen a similar line as a result of "sharpening". It would show up on my monitor but was virtually invisible when printed.
