What my customers are saying...


A new level

Exposed is really good Gavin Seim. I started in film and had a good working knowledge of the Zone System. You have taken that to a new level for me and helped me learn to apply the deliberate tonal mind set to digital. Especially if the scene isn't fast paced (such as landscape). This however can be used even in weddings if you think about it while setting up the images. Amazing work! If anyone here is considering the purchase, stop what you are doing and go buy this series. It rocks!!!!

Opened my eyes

The workshop did open my eyes. You explain perfectly how to combine all aspects of light, tones and planning can/do make a better picture.

Improved my understanding of light

Thanks for putting together such an enlightening video - Exposed really brought a lot of things home for me. My understanding of exposure and light was enhanced and cemented. Lovely. Thanks

It is 1:17 AM, just finished Ch 1, "Hitting the Road" and I am already intense about the Training. The video quality is absolutely outstanding, and the background music, "America the Beautiful", was a perfect choice and you my friend are inspirational. Love your passion!


Entertaining and Educational

Exposed is both entertaining and educational. It is very much a conversational exposé that takes you through all aspects of working a photograph to capture exactly what see in the field

Best ever

Hey Gav I've just completed the workshop and really enjoyed! It's the best workshop I've ever downloaded!, Some workshops I've previously done show the photographer taking the picture but never show why they've decided on a certain set up,

but you've not only explained 'How' but more importantly the 'Why'
I have to admit the Zones was totally new to me but you've explained it so easily I can put it straight in to practice, It's opened my eyes to a new way of seeing Light, and this can only be a good thing for my photography,I agree with Susan no matter what level your photography is at you will come away learning something from this Workshop, I certainly have and for that I thank you, Keep up the amazing work 🙂

Fun, beautiful, informative...

Was recently drawn to your work through a Facebook ad you did about zone system. Enjoyed both Exposed and PP very much. Fun, beautiful, informative, great music, etc. Loved the passion that went into producing both.

Blown Away

Heather and I had the pleasure of getting a copy of Gavin Seim’s latest video workshop “EXposed” and we were totally blown away. We’ve seen so many video workshops lately on everything from lighting, to business, to workflow and what Gavin has put together really stands head and shoulders above so many others in terms of content and quality

What do you want to know about light? EVERYTHING!

Do you ever struggle getting perfect light? You know what you expect, but the result does not live up to it. EXposed solves that with a hands on study like nothing else in the industry. No matter where you need to improve, Exposed is going to help. It makes EVERY photographer better. Not with magic software or fixing it later, but with history's best techniques gathered into one powerful series.

Most workshops only offer recipes; but they don’t change how you see. Exposed brings something no photographic workshop has done. It helps you understand how light works. How to control it and how to make it magic. We cringe when people miss out on EXposed because it's a game changer. It's the result of decades of techniques developed by master photographers around the world and brought together in one a simple fast workshop.

You CANNOT LOSE with EXposed. That's why we give you a 100% money back guarantee and get a return rate that's only a fraction of one percent. But be warned. Once you're EXposed you never go back." -- Seim

Learn FAST: Unlike recordings of live workshops, Exposed is a production designed to be seen as a video class. It's not gimmicky or cluttered, it's timeless information that's been highly condensed and professionally presented to make it as digestible and flexible. Within a couple hours, you'll be applying what you've learned and adding it to your existing skillset.

The Light! Understanding it's nuances and having the ability to control it instead of it controlling you, is the key difference between boring snapshots and incredible photographs. – EXposed is the first film that looks at every aspect of how we use light in photography. It's like no educational course you've ever watched.

The Journey: Seim has been studying what makes light tick since age twelve. More than fifteen years later, he's more passionate than ever. Inspired by the masters, EXposed is a master class on light for all skill levels as we travel around the USA with the Super Camper and a sack of gear. A decade and a half of learning into the most breathtaking study of exposure ever released. Exposed is a workshop that entertains, educates and explores not only at how to photograph light, but how to truly see it.

The Production: EXposed was produced on location as Seim travels around the United States. Often filmed solo, captured live with wireless microphones while making the shot. Sometimes with a small team. Every stitch of was recorded on location. EXposed a labor of love. No matter what your experience level, you're in for a journey that will challenge everything you thought you knew about light.

Accolades & Awards: EXposed won the coveted Hot One award from Professional Photographers of America in 2013 and has received rave reviews throughout the industry since it's release. It represents a unique study that builds the foundation of our craft and makes the complex things about light, simple.
