f-stop is an abbreviation for a camera lens aperture setting that corresponds to an f-number, which is the ratio of the focal length of a lens to the effective diameter of its aperture.
With Christmas comes a reminder that the beauty of creation touches the soul of all us, with opportunities to capture images of the season. The Times welcomes readers to send us their best photographs; whatever they capture, an unusual image, person, place or thing, we want it. Photos can be of any subject, but we especially like people.
Please send photographs to David Adlerstein at firstname.lastname@example.org. For more information, call 653-8894.
