John Peltier

I've been teaching in-person photography lessons since 2017, primarily to beginners using various camera models. Everyone has the same struggles, and I'm sure you do too. I've brought a proven method of addressing those struggles to these online courses.

Aside from teaching, my photography passion is storytelling. I've completed photodocumentary projects worldwide over the past 15 years, in locations such as Haiti, Guatemala, and Uganda, and have been featured in publications including New York Magazine, the Los Angeles Times, and the U.S. National Park Service.
