Is it possible to take photography lessons online for free?

"There are luckily many photographers providing helpful tips, hints, and tutorials around the World Wide Web. In fact, a lot of the photographers that you will find are self-taught themselves! Thanks to the internet, you can easily self-teach a basic knowledge of camera functions, lighting, and timing. Unfortunately, more in-depth training online you will most likely have to pay for. But if you're willing to be patient and take the time to learn basics, and then develop your self further through trial and error, there's no doubt that you couldn't be offering online advice yourself one day!"
