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.

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

comment Image in focus at the back (LCD) but not when shown in computer
How are you looking at the image on the camera LCD to assess sharpness? Are you looking at the whole picture, or are you zooming in to a section to see pixel-level detail?

comment How does a modern DSLR camera and lens actually adjust its aperture
Lacking a DoF preview, you can also just set a manual exposure that's long enough to observe the lens stopping down, e.g. 1 second at f/16.
