Radiantvista daily reviews photoshop workbench etc

Since i've started teaching digital photography to the elders, i have found some really fantastic educational sites about photography on the web. Radiantvista is currently my favorite. The front page has random photos that are very inspiring so that each time you drop by there's a new one.
Everyday i check out their daily critique. Brave souls send in their shots and the fellas give a detailed critique. They start with what they like best (quality of light is a big one) and go into detail about what's good about the shot. Then, about one third to one half the way through the presentation, they switch to what could be improved about the photo. It's interesting the way they can make a photo that was good look really great with a simple crop, color correction, or creative use of the spot healing brush! Then, right before the end, they summarize what's good about the photo and they always thank the folks who submitted the photo.
I love these critiques because for me it reinforces that close critical eye that we need to use when taking the shot and when editing in photoshop. (I also like to guess what improvements they will make and it's fun when I'm right)
Speaking of photoshop, there's another section of the site dedicated to showing in detail what you can do to improve a photo in photoshop. Some are basic techniques, like how to drop in a new sky, and others are more advanced, showing consistent workflow, use of masks, color correction with adjustment layers and so on.
Another part of the site has video tutorials. These are long and amazingly detailed. Like the daily critique, the videos run on quicktime which is so much better than windows media player. All you Mac users already love Apple's Quicktime but for you all still using windoz go here to download it:

My absolute favorite tutorial is the tutorial on composition. This is the class that i had the hardest time teaching because every resource that i found had yet another take on it. But this tutorial is so comprehensive yet clear and simple it's accessible for everyone.
They also have PDF tutorials for those of you who miss reading. Seriously though, these are good for opening up photoshop and working along side. Also in PDF format are some articles, or at least the first one about "The Myth of Talent" which makes the point that you need to work at it and even if you are not that good to start out, if you keep at it you can get really good. I'm not sure this is always true. I don't think it would matter how much i practiced singing for example.
Radiantvista also has podcasts. I feel like such a techie when i download these to my iTunes and play them. Yet it's a real throw back because it's like listening to the radio. I don't own an iPod, but i suppose if i did i could listen to the shows on the run. The shows tend to go into depth about a technical subject like the one about using the RAW format to your best advantage and the latest one about how to use charts that tell you when different stages of twilight will happen where you want to shoot, so you can know when to get out and get that great landscape in the best light possible.
Why do these guys give away so much knowledge? Well besides being in love with what they do, the site also promotes their workshops. Unfortunately for me they are not giving one in my area anytime soon, but i'll be the first to know when they do! What could be improved in a perfect world? Well getting a woman photographer on board would make me feel more at home, but that's just me!
So I give the site an enthusiastic five stars.
