Better than Luminosity Masking, the original Zone actions.

Luminosity masking is usually convoluted. That's why we made Lumist 2. Integrate luma masking with Zones in real time. Easy layer building, and auto masking actions let you to advanced edits fast without hassles or confusion.

Love these

I have these - by far the best set of actions I've purchased in a long while. Credit where it's due, I love them!

Lumist reviews...


Good stuff

Good stuff... Your actions are the basis of my workflow - for many years now.

Jean-Claude Louis

Wow another great tool Gavin! Time to revisit a few images for sure!

Doug Parks


This is a great plug-in for Photoshop and doing exposure correction. It takes a lot of the mystery out of the Zone System of exposure. It is quite easy to work and to deal with. I highly recommend it. Also, Lumist works with the Alchemy actions also from Seim.

Mike Perry


Awesome is the right word

Mike Jackson


Your Photoshop actions and Lightroom presets are excellent, much deeper, and more involved than others I have seen

Charles Kinghorn

I love all of them...

I have NHDR 4.0, BlackRoom, and Lumist. I love all of them.

Vipul Patel

Highly reccommended

Lumist gives you an easy way to see and adjust every tone value in your image with surgical precision, and that's just the beginning. I can't recommend this product highly enough. Thanks for all the work you put into this, Gavin!

Changed the way I now expose and create images.

Lumist is the set of Photoshop actions which helped me see and adapt both the light and the shadows using the Zone System. Having these new tools changed the way I now expose and create images.

Thank you for your pragmatic approach by explaining and porting ‘old school’ techniques, like the Zone System, into the modern digital era where Photoshop rules the way we create photos.

Daniel Kinner

I'm really pleased.

I bought Blackroom and Lumist and I'm really pleased.


i bought Lumist a few weeks ago. And wow it has really been a great tool in Photoshop. If you pay attention to tonal levels and want to make quick powerful action adjustments by selecting tonal levels rather than the blunt tool of luminosity masks you will love this set of actions.

Luminosity Masking, Retouching and Zones made better.

LIVE Zones and Tones are a game changer. Lumist actions take the concept of Luminosity masking, merged it with Ansels Zone System. It's smarter and easier to use than panels. Other tools have tried to copy Lumist, but none have done it. Lumist 2 takes tone control in PS to new level. Epic effects, and controls combined with the new LIVE TONE system that lets you see and edit ZONES in real time! 

What started as simple effort, trying to better map and visualize tone, resulted in Lumist 1. Lumist 2 is a system in itself, allowing a level of simple, intuitive control over tone that we've only dreamed of until now. It's what Photoshop should do already, but cannot. Lumist 2 uses zones to give you visual feedback on your light, helping you make better images in camera. It also allows you to manipulate that light in real time whether it's with portrait effects, color tones and overlays, burning, dodging or perfectly masked curves and levels layers that effect only the parts of the image you want.

Lumist 2 is a complete system. But it doesn't stop there. Whether you use a Lumist action, make your own or apply any other layer, Lumist can see your tones and let you mask and make creative edits and controls on everyone. Lumist 2 takes Zones, Luminosity masking and Photoshop and makes them what they were meant to be all along.

Live Tone Map: The Total Map changed the way we edited images and gave us deeper insight into our light. With the new, faster Live Tone, the Total Map updates in real time as you work. It works exactly like it sounds. Lightened your image? darkened it down? Live Tone shows your changing tones so you can decide how to use them.

Perfect Selections:  With these tools, you can choose any part of the light and apply it instantly to any layer, group or intelligent effect. Select Zones, skin tones or colors and apply effects and layers fast with the beautifully designed non-destructive vertical editing system developed to give you better results.

Effects, One Clicks and Silver: The next generation of Lumist's Color Luma. Detailed color control for specific areas of your image. Live Tone showing that one spot that is just a bit off? Luma Painters can fix that, no problem. Need actions for Silver? Or maybe a quick, powerful one click? All here, and you are gonna love'em.


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 publications 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 there's a lot more to learn.

Wanting something calmer, I moved to Mexico in 2017, exploring the magical light of the South while creating new tools and workshops as well as video and the Pro Photography Podcast.

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! There's lots of videos, podcasts and free things here. So look around and if you have questions I'm here to help --
