I am often amazed by the amount of free information to be found on the internet if you know where to look.
Creative Live hosts live classes on subjects such as studio lighting and HDDSLR film-making with pro photographers such as Zack Arias, Vincent Laforet and Chase Jarvis. These are not short tutorials but comprehensive courses of around 20 hours.
The classes are free to watch live but you have to pay if you want to download and watch them at your leisure. At US$80-120 though, I think they are an absolute bargain considering the amount of information they contain. I’m looking forward to watching the What’s New in Photoshop CS5 in the morning with some coffee and cake.
The next free course is July 23-25 with David duChemin and Chase Jarvis on improving your your photography and post-production. Details here
