comment Projector Design and lenses
Why is it necessary to build your own projector? You could get a 35mm slide projector off eBay, even a nice one should cost under $500.

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.

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.

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.
