There are many fantastic photography websites out there and way more than I have time to read. Here are a few of my favorites. I'll add to this list from time to time when I find something that I begin reading regularly.  In the meantime, chew on these:

Mirrorless Minutes
I'm a little biased regarding this site because I personally know a few of the individuals that run this site, but if you shoot with mirrorless cameras, this site is worth checking out.  They also have a bi-weekly video/audio podcast that is on my podcast list as well.  

Mirrorlessons
Another great site for mirrorless users.  There is a wealth of information here including, in-depth reviews, interviews and tons of articles.

Digital Photography School
If you are just learning photography, this is a great place to start.  There are plenty of articles, how-to's, tutorials, etc.  Lots of well-known contributors with a constant flow of new material. 

Photofocus
Another great resource for the new and seasoned photographer.  They have a podcast as well, although I currently don't have room for it in my listening schedule.  

Digital Photography Review
If you are a photographer and you don't know about this site, you must check it out.  Hands down the best and most thorough gear reviews anywhere.  If you know of something better, please let me know.

Mike Moats
I had the pleasure of taking a macro course from Mike back in November.  I'll be writing a post about it soon. If you enjoy macro photography, check out Mike's blog.  He posts daily and even includes a video tutorial from time to time. While you are at it check out his YouTube Channel for some great macro tutorials. 

Nicole Young
I first found Nicole through the TWIP podcast. She's a writer as well as a photographer and has many books and e-books on various topics including Canon gear, onOne Software, food photography and more.  If you haven't thought about food photography before, you will after reading her blog.

Brian Matiash
Brian is a recent convert to the mirrorless world. Check out his free e-book "Moving to Mirrorless".  He discusses why he made the move to Sony and the images he shares will make you want to drop what you are doing and go out and shoot.
