Hi! I am not sure how long this will be available - but the iPhone Photography School has released one of the videos I created for their Masters Course and you can watch it for free!
Typically you have to pay to be a part of their Masters group (although I have heard they're discontinuing this) and you get access to a grouping of 6 videos each month. This is one out of the six I did one month on Nature.
Enjoy!
