NO!

Did they come straight out of the camera looking like that?

No, off course not, but there's no "manipulation" if the image itself involved. It''s simply filtering layers and enhancing what's already in there.

OK, I get it. Each 'filter' process accumulates into those kinds of effects. It happens to me a lot. The edge enhancements are particularly bad for that sort of thing, especially if you then apply contrast increases and or color saturations afterwards.

I'd go right back to the originals and start from scratch with nothing more than straight enlargement until there's nothing to see but the pixels of the medium that recorded it. One single contrast multiplier may be ok at that stage but don't keep on applying process to it.

The use of the word "filter" in digital photography is very misleading because each filter IS actually an image manipulation algorithm that will start off the process of artifact abstractions that will then be further exaggerated upon further use of processes.

Well, they're not Pixel Anomalies if that's what you mean, not at all.

But... I am not in the convincing game, purely in the sharing one. Think what you like, I will not think any less of you.

MS, I agree and accept your train of thought, not to dissimilar to findings elsewhere. Also the lake may have been created as a cover, as the details look incredible technical.
