comment Will any non-AF lens work on a Nikon camera with built in AF already in the camera body?
Wikipedia also has a good timeline and description of Nikon lens technology under the title "Nikon F-mount". To be super brief (and not covering very old or very odd lenses), there are AI/AIS lenses that don't autofocus at all and AF lenses that either have their own motors or use the one in the camera. Note -- on many Nikons you can get focus confirmation with the older AI/AIS lenses.

The phenomenon is known as "banding", where gradients show abrupt shifts

comment How should I specify minimum quality requirements for images submitted to my image archive?
Sorry, yes "dimensions in pixels" would be a better way to word that.

comment Is it possible to share albums privately on Flickr?
Or just create a separate account for just your family photos, if that is the only set of people you are concerned with.

answered Why does crop factor apply with APS-C lenses, and why aren't these brighter than FF ones at same aperture?

comment Is CMYK less blue than sRGB?
Modern color management just asks that all the devices in the workflow to have ICC profiles. That way the computer knows how the monitor displays colors, how the file expects its colors to be displayed and how the printer displays colors. But would a file that uses ProPhoto RGB give different results than a file that uses sRGB when printed? Both files will have the colors mathematically mapped to the device profile, so I wouldn't expect the difference to be huge -- but it is a good question.

comment Did film photography have lens correction counterparts?
Not an answer, but back in the day before computer pagination they would sometimes use an anamorphic lens on a large format copy camera to squeeze artwork (or text, or even whole pages) horizontally or vertically. It was about only way they could do non-proportional scaling.

comment Why image at 400mm is LARGER THAN DOUBLE of image at 200mm? (according to lens formula)
On the subject of 2A (crop factor = subject enlargement), I understand what you are saying, but from the standpoint of the image projected onto the sensor in principal there is no magnification. Here is another website that covers the subject: luminous-landscape.com/tutorials/understanding-series/… A quote: 'From Ansel Adams in his classic book “The Camera” (New York Graphic Society 1980) -- "All lenses of the same focal length give images of the same size at any given subject distance."' It's a technical point, but you seem like a smart, technical person.
