Better Luminosity Masking with the original Zone based actions.

Luminosity masking is usually convoluted. That's why we made Lumist. Integrate luma masking with Ansel's Zones in real time. Easy layer building and auto masking PS actions transform photos fast without the luminosity masking hassles.

Old dog learns new tricks

Gav, your brilliant 'Seim re-touching Effects' video workshop series, coupled with the range of LR pre-sets has given me motivation (and a heightened awareness) to re-visit just about everything I do in the image making process. I can only say thank you - best value for money I have encountered - Gavin Seim is not only a skilled practitioner, but a very accomplished and effective educator who is obviously passionate about every aspect of what he does. As an 'old dog', who has certainly learnt 'new tricks' I totally recommend this site and its resources to every photographer, regardless of their level of involvement, expertise or skill

Lumist reviews...



Awesome is the right word

Mike Jackson

I'm really pleased.

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


Excellent Service

Excellent customer service, and if I got nothing else seeing the Zone Map is making me think more about light and tones. Well worth it!

Lisa Bartek Reynoldson

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.

Phillip Ziegler


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

Works perfect

This set of actions works so perfect! very easy to work with.

Hugh Mobley

I love that it saves me time

Gav, I make it a point to purchase your products and use them with capture one 22. I love that it saves me time having to work on my images.

Raul Bautista

I have to battle to overcome the feeling that I am cheating in some way when I use the actions because it is so easy to use and oh so effective.

David Roby


I finally purchased Lumist, yesterday, and was wowed immediately by the difference it makes. As a novice, it's my first introduction to zones, and I'm thrilled to have the new action.

Ron Hoehn

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

So much faster than V1!

Installed Lumist V2 and works great! So much faster than V1!

Love your actions for photoshop

Hi Gavin, love your actions for photoshop, they're a fantastic time-saver.

Robert Huber

Bought Lumist a while back and have been just too busy shooting to do any serious post processing. Finally got around to it last night and WOW! This is certainly a game changer. Will be interesting to go back to old photos and see what I can pull out of them. Looks like I'll have a lot of reprinting to do in the near future. Thanks for all your hard work Gavin.

Keith Doucet

What an amazing set of actions. I just started playing with these and am totally blown away by the results. Beautiful!

Kimberly Gordon


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

Charles Kinghorn

Another home run Gavin. Toss all my other frequency separation actions. Always trying to get more bang for my buck with actions so I have fewer in my list but they allow me to do more.

Phillip Ziegler

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!

Lorraine Jardim

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

This is amazing! best actions I ever purchased, crystal clear explanation of how to use the actions. thank you Gavin ...

Vipul Patel

Great tutorial...

Thank you for this great tutorial! Very pleased with Lumist 2.5 and this Shadow Hackers workshop!

Daniel k

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!

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.

Who is Seim?

I'm Gavin Seim and I started studying photography in 1997.

As digital arrived, I went all in. I got to study with masters like Ken Whitmire. In 2009 I founded the Pro Photo Show podcast and eventually my YouTube channel. I started creating the professional developing presets when Lightroom V1 launched. Then Capture One Styles, Photoshop Actions and photography courses.

20+ years in the trenches earned me a Masters (M.Photog) from PPA. I've been featured, won a few awards and now I live in Mexico exploring the magical light of the South while creating new tools and searching for shadows.

You're rightly skeptical on online photography tools in a market filled with junk. That's why all sales are NOT FINAL here. I guarantee every tool and workshops 100% with a 31 day No-Regrets Guarantee!  

There's lots of videos and free stuff on the blog too. Look around. If you have questions I'm here to help, just send me a message | Gavin Seim
