comment What is the relationship between focal length and minimum focus distance?
The manufacturer's web site will usually list the specifications for their lenses, including minimum focus distance.

comment Astrophotography, image stabilization on or off?
I'm not sure that really answers the question, as such advice surely refers to a fixed tripod, not one mechanically connected to a tracking motor that could induce vibration. (I also find such advice to be an oversimplification in general. I've been in situations where high winds made stabilization helpful even on a fixed tripod.)

comment What are the differences between D-76 and Xtol?
I used Xtol regularly, and the only film that didn't give me enough grain to focus on was Agfapan APX 25, which has been long discontinued. I don't think you'll have any problem with 400-speed film.

Guess as to the meaning of "in gron"

revised How does a camera artificially decrease DoF of a shot from a single position?
Adding DoF would mean more of the scene is sharp. A blurred background = decreased DoF

comment Why change to open-aperture metering when this causes the need to stop-down for old lenses
I'll add that in the Pentax system, the mechanism needed for old lenses to meter wide open is called an "aperture simulator," and Pentax/Ricoh have never put one in any model of DSLR.

Upvoted for the Steel City, the most photogenic of skylines.

comment Does lens age affect color produced?
My "negativity" (read: downvote) was because you used the word "nonsense" about a real phenomenon. Even if you consider it rare, it's certainly not nonsense. Here's a Super Takumar 35/2 that I briefly owned... the discoloration was apparent by looking through the lens, or in shooting with different lenses. dl.dropboxusercontent.com/u/20239870/20140202-K5ii-04903.jpg

comment Why does “bulb” mode usually rely on holding the shutter button?
I think you're confusing bulb mode with F/FP/M synchronization for flash bulbs. en.wikipedia.org/wiki/Flash_synchronization
