Just to address this part of your post, I don't have evidence at hand to back this up (I've searched), but I'm fairly certain that today's incandescent bulbs are not substantially different from those made 50, or even 75 years ago for that matter. Despite much vaunted "technological advance" in things electrical, tungsten is still tungsten, and incandescent bulbs are pretty simple devices. No great magic there, so I think the results one would get with that source of illumination would not have changed much, if at all.

Oh I don't know, David. Just a 30 second search has produced this site:
http://www.lightbulbs-direct.com/article/colour-temperature/
where you can clearly see the differences with modern lighting. It provides technical information on the actual colour temperature of many light bulbs that you can get at the local shopping. Check for example the light saver bulbs and their colour temp: I guess 6500K is a bit different from 3200K, no?

At first look you are absolutely right, tungsten is tungsten. But there is such a thing as glass and mirror coatings. Once again: check that site carefully for many, many examples of classic light bulbs with completely different colour temps. For example, these:
http://www.lightbulbs-direct.com/product/2540/m258-12v-50mm-4000hr-cool-white-50w-38-degree-4500k/
are what I use in my house spotlights. 4500K, dude.
What can I say? Perhaps tungsten is not tungsten after all?


Like I said, folks: open your minds up! Standards of 50 years ago are NOT today's standards. We need to rethink all those "recipes" of yore, in a modern context.
