I will buy Popular Photography and Photographic on the stand if I see them and happen to think about it, but if I don't, I don't mind missing them; they're mostly ads, junk, and reviews that I have little respect for.
It costs a mint to subscribe to B&W Magazine in the USA - it is a weekly magazine. Well worth it, in my opinion. I read it primarily for Ivor Mantanle and old-what's-his-name who graces the back page. Pure dynamite, and greatly enjoyable.
Shots is the best magazine of hardcore B&W photography that there is, period, say no more.
Lenswork is the best magazine of art B&W photography that there is.
All in my humble opinion, of course.
But for pure photo-magazine brilliance - I paw through my growing collection of photography and camera magazines from the 1900's through the 1970's. They grow in brilliance and relevance starting in about 1942, and topping out in about 1972, then they begin their decline to the sad state they maintain today.
You have NO IDEA what a photography magazine can be like until you've picked up a 1958 issue of Popular Photography or Modern Photography or The Camera and read through it. Great articles, great interviews, equipment is reviewed without that need to call everything 'great' and 'fantastic' and 'breakthrough' and so on - superlatives seem to be held back for actually cool stuff. Amazing to see what they were predicting for the future of photography back then, too. I've read articles from the 1950's where they were talking about using electrically-charged plastic film to hold an image - no, they didn't have the concept of the ultra-tiny computers on board or the CMOS sensors, but they understood well enough where things were headed. INCREDIBLE! And you can buy a stack of the musty old things from shutter bugs who are moving to old-folks' homes and need to clear them out - 5 bucks for a couple year's subscriptions. Great good fun, for a geek like me.
