Ok, you hate Pop Photo right! Sure - I do. They never say anything bad about an advertiser, and they reprint the same articles over and over. Well, I've got a confession. I've not missed an issue since 1978. Well, it was called Modern Photography for a while, but when Keppler and crew moved over, they changed names. And they have been the primary source of my photographic knowledge (well, in addition to about 50 other magazines, and in the last 6 years, online fora (like this place, DPR before that, and Nikon tech before that)) since digital. But guess what - that old media publication just came up with something new! Well, new to me anyways. It's about calculating the hyperfocal distance, a topic I have seen frequently. And wow! They have reduced the hyperfocal distance - the distance to focus at to get everything from the distant horizon to the closest thing you want to focus on, in acceptable focus, for any given f-stop - to a single 'easy to punch in to your calculator' formula: hyperfocal distance = '(focal length) squared ' divided by 'f-stop times 0.3' Cool, huh?
