I have a pretty negative view of all the mainstream photography magazines. They have some decent articles for beginners, but rarely anything for even a moderately experienced photographer. Their equipment reviews are just glorified ads. I know that all magazines exist to sell advertisement, but the division between editorial content and advertisement seems particularly week in photography magazines.
I currently get two photography magazines. Rangefinder and Photoshop User. The first is geared towards pro wedding and portrait photographers. It might not be a bad magazine for them, but I find it to be absolutely useless. I got a free subscription and have no intention of extended it. Photoshop User is part of the Kelby empire. I find it to be a reasonably good source of articles on using Photoshop and other Adobe apps. I preferred Layers, but the closed it and folded it into Photoshop User.
Honestly, I think the web has nicely filled the hole that photography magazines would have traditionally filled. There are so many great sites (Luminous-Landscape, Fred Miranda), blogs (Stobist, Joe McNally's), review sites (DPReview, The Digital Picture), forum (Texas Photo Forum, DGrin), and sharing (Flickr, Google Plus). I've been told that there are some excellent high end magazines, but I haven't subscribed to any.
