Another great resource for photographers is the Lastolite School of Photography. Lastolite is a company that manufactures an array of high end photography gear, and their “School of Photography”, although is mostly geared towards Lastolite product knowledge, does provide great tips on photography (lighting, portraiture, etc.). The format of this School is online videos, hosted by the very knowledgeable, professional photographer Mark Cleghorn.
The tutorials can be downloaded from iTunes, or from the following website:

You can spend hours browsing the videos, so what are you waiting for?
