Just because you didn’t get to go to that awesome photography conference doesn’t mean that you can’t learn something from the pros! Occasionally, we’ll be featuring a recommended photography lecture or interview on Phototuts+.

French photographer Pierre Gleizes has shot some of the organisation’s best known photographs over the three decades he has worked for Greenpeace. In this video, you’ll see photos from Greenpeace boating activities including documentation of baby seal hunts. Gleizes talks about his approach and how he considers himself both part of Greenpeace and a documentarian.

You can see more videos from Greenpeace on their Facebook page.
