IMHO, the Luminous Landscape should be on every photographer's reading list.
Michael Reichmann, the original Editor-in-Chief (now decreased, 5/2016), had a long career in photography and technology, and offered some of the most insightful commentary around on industry trends, gear, technique, composition and shooting venues. Michael's camera and lens reviews emphasized pragmatic usage in the field, and always offered a unique perspective.
The site offers many articles and tutorials, as well as training videos on a variety of subjects, and is updated regularly with new material. Many good photographers inhabit the forums, which are active and well-moderated (i.e., not over-run with trolls). The site has been around since 1999, and currently has well over a million visitors a month from all over the world. The site still has a lot of free material, but some is only available to members ($1/month subscription fee).
Michael was well-known in the industry, and had industry relationships that enabled him to comment authoritatively on industry trends and products. He was opinionated and no-nonsense in his commentary, but willing to change his views in the face of new information. Or just when, in the passage of time, he saw something differently - I found that refreshing.
|Digital Photography Review||
Digital Photography Review is the largest camera-gear-head site on the planet, and well worth getting to know.
It offers the most comprehensive camera reviews around, and has a nice side-by-side comparison guide, which allows you to easily compare 2-or-more cameras. It also has useful Buying Guides for various types of cameras including a DSLR Buying Guide, a Mirrorless Camera Buying Guide, and a Compact Camera Buying Guide.
The forums have a lot of useful information and good folks but, IMHO, are not particularly well-moderated, as trolls hijack threads there a bit too much for my taste. Definitely visit and use the forums - just be prepared to sift through the chaff to get to the wheat. (In dpreview's defense, I'm sure part of the reason is that its just very hard to keep up with the volume of forum traffic. The site has been a smash hit and gets millions of visits.)
Phil Askey founded the site in 1998, which was relocated to Seattle from London and sold to Amazon in 2007. Phil left in 2010 to pursue other interests.
|Imaging Resource||Imaging Resource is a great site for camera reviews and lens reviews. But it also features many Photographic Interest Items on its main page, and is well worth visiting regularly.|
|Camera Size||Camera Size is a little gem that allows you to visually see the size of two different cameras side-by-side. So, if your question is "how much smaller is Camera X compared to my current Camera Y?" ... then this is the site to visit.|
|DxOMark||DxOMark is a great site for camera lens ratings.|
|Sightsmap||Sightsmap is hot! When you go there, press the "heat" button at the top and you will see a "heat map" of the entire globe, wherein the "hotness" of a given location depicts the total number of photographs taken from that location. Its a very interesting and informative way to see which locations on the globe have been photographed-to-the-max and which locations haven't. Some of the locations will surprise you, and others not so much. Have fun with this one.|
|Photography Life||I've been reading Photography Life for several years now. Nasim Mansurov and his team do a great job of covering a wide variety of interesting photographic topics. Well worth visiting.|
