Unleash the Develop Module!

Sliders is a simple powerful workshop. You won’t walk away with just a few tips on how to use develop tools. You’ll walk away with concepts that will change the way to process photos. You’ll learn right and quickly with Gavin’s easy to follow style.

No more LOUSY processing!

There’s too little knowledge out there on “quality” processing. No matter what version you use, you’ll learn something new. While this workshop centers on LR, if you use different software like Aperture, Capture One or Bridge; the principles of the sliders work perfectly in nearly any environment.

Get Sharper images.

Seim teaches you how to understand the fundamental nature of a great process and shows how he makes his international award winning images. Great images start in camera. They are finished with skill in the digital darkroom that many photographers are missing. That’s about to change.

Light and Dark.

SLIDERS teaches you how to deeply understand post production tone in your images. How to control light and make shadows rich and detailed. The Digital Darkroom is relativity new and Seim brings years of experience to the table to examine what makes it tick.

Perfect Color & Tone.

Most photographers have barley scratched the surface of what can be done with digital color and light. Sliders take that on simple and effectively. You’ll be doing things that you never knew were possible.

A Speed Learning Course.

Gavin has years of experience teaching Lightroom and award winning photographic classes. Sliders is a concise workshop that gets down to the nuts and bolts of light and better post production; giving you the skills you need to take yourself further. It pays for itself so fast, you’ll forget what it cost.

I'm Gavin Seim. I'm a Shadow Hunter

I started photography in 1997 at age 12. I'm a PPA Master, Hot One and Loan Collection winner and Lightroom expert. My images, tools and workshops have been featured in books and throughout the industry.

I was born in WA USA. I started working pro (using that word loosely as I sucked) using film at age 16. It was not easy to find training then and often I beat my head against the wall to win. 20+ years in the trenches earned me my Masters (M.Photog) from PPA but it taught me that's just the start.

I moved to Mexico in 2017, exploring the magical light of the South, creating tools and workshops as well as the Pro Photo Podcast. There's lots of videos and free things here. If you have questions I'm here to help

You're rightly skeptical of photography tools in today's market. That's why all sales are NOT FINAL here. I guarantee each tool and workshop with my 31 day No-Regrets Guarantee! --
