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.

If you want to get a better picture of the design of modern multi-element lens ... I'm really not sure where to go. A starting point might be advanced amateur astronomy, where there are still folks who shape their own lenses.

comment Exposure compensation or ISO sensitivity?
Assuming you have been correcting your underexposed images in post, I wonder if a better phrasing of the question might be, "What is the difference, if any, between changing the ISO and underexposing and then correcting in post?". Does that make sense?

revised Is f/number more relevant than aperture and/or shutter speed?
Suggested clarification that some modern lenses do have mechanical aperture rings.

Certainly -- I still have a Nikon FM2 and used to be a huge darkroom snob. I'm sure as long as Leica is in business and view cameras are sold there will always be mechanical aperture rings.

You might have better luck at the GIS stack exchange site.

comment How can I tag my photos with electric compass info giving direction my camera was facing?
The problem, I think, is that Surveyors are going to use theodolites (very accurate, a lot more expensive than $10) not DLSRs and for most photographers elevation/depression is mostly pass/fail (is the camera level or not). So the thing that you are looking for is very rare and/or expensive. Looking on Google, I could only find one example of someone rigging one up on their own and only one theodolite (a total station) that had a digital camera. It is a Topcon IS-3, which looks to be a US$ 14,000 machine. But, there is an iOS app called "Theodolite" that seems to do what you want.

comment What advantages does 35mm film have over high-end digital?
I guess I'm looking at this from the standpoint of an old film guy, who expects camera companies to carry the exact same model for decades. Nikon's F1 came out in 1959, the F2 in 1971, the F3 in 1980, the F4 in 1988 ... oh heck -- ever since they invented the integrated chip everything has gone to hell ;-)
