For when you want to create epic early era emulsions like platinum and cyanotype.
Watch the video and see how.

The first time I saw a platinum print I was amazed! - I'm Gavin Seim, my career started with film. But I was young and digital was new. I started to connect film to digital in new ways and became obsessed with the magic of silver prints, then early era emulsions like Platinum. I saw that print and said.. "Wow, I'm going to make that for digital."

So I built Emulsion so we can create deep emulsions easily!

... It was that moment admiring real platinum prints at national competition.  My mind started working. Not to take away from the beauty of this classic process; but to honor it by re-creating the aesthetic that real metals in prints could give us.

So I started studying what make these classic printing methods beautiful and deep. I wanted us to have more than just tints and color filters.

Years of that study, led me to the techniques that are used in Emulsion 3 to give your images a look like nothing else but the darkroom can give. I've spend years making a system to give us an easy digital emulsion darkroom within Photoshop.

What actual Emulsion users are saying...


quite pleased...

I am quite pleased with the results. Thank You Gavin.

Ernst Ulrich Schafer

I especially like the Platinum look. It's so great, I converted the results of the action into a LUT. What's missing? A nice sepia tone.

Glenn Mitchell

I just bought the package and tried it with one of my photos and the results are pretty amazing.

Andreas Heuer

I just tried the Platinum action on scanned 4x5 images

I just tried the Platinum action on scanned 4x5 images, and it looks gorgeous on-screen and printed on Japanese Washi paper. This is the look I have been looking for. Thank you.

Richard Man

Love it. Takes a bit of getting used to. Almost darkroom, but not quite

Kerry Blakeney-williams

This is the look I have been looking for. Thank you.

3 Dimensional Chemical Toning

The reason Signature Emulsion has always been so impressive goes back to the very first version which only had the Platinum effect. This was my first print from digital platinum.

I took complex layer building and tone separation using masks to give a rich complex look that's not possible in RAW software like LR. Then we made it simple.

In V3 we've taken that further with dynamic luminosity masked 3D tones. Adjust the base layers and tone curves, and the tints alter in real time to give you a different mix and a more darkroom like result.

Platinum, Wet Plate, Cyanotype Looks

These looks were are hard to achieve on digital until now. But these actions give you epic emulsion and then let you control every aspect of the result.

V3  brings amazing update to the Platinum and Cyanotype looks as well as the epic new wet plate look inspired by the classic celluloid processes of the past for a rich, ultra detailed look that takes you back to the roots of great photography.

Integrated Texture tools in simple actions!

Textures are a pain because you're always going to find files and then deciding how to overlay them.

In Emulsion 3 we made that better with classic papers and chemical inspired textures that can be instantly added on top of your emulsion effect thanks to our new seamless texture patterns that are included in Emulsion 3. Add a texture on top of your effects at any time and have an instant overlay while retaining total control.

Easy... Watch the Emulsion 3 actions Workshop!


The truth is that people get upset that I made Emulsion work so well.

"Gavin it's manipulated, it's fake!" - "You're a fraud" The passion people have for darkroom prints is part of why I started this project.

But these comments are only from those that have not yet used the process.  As I work to make it better with each version, I study realism and the darkroom. 

The old masters used paper and chemicals in the darkroom to create effects and manipulate light to their vision. Digital is just our new way of using the light.

It does not feel fake or staged because it's not. Emulsion is a natural deep processes that works with digital and prints.

You're going to be blown away.

Emulsion 3 creates looks for your personal vision each time. Honestly, it does it so well I thought of keeping it only for myself. But I wanted you to explore tone and share what you create.

Emulsion honors the organic processes of the darkroom, while creating a new process of it's own with infinite tonal possibilities.

You get a unique result every time as the process creates layers and responds uniquely to the tone of every photo you process. Creating a darkroom like experience that's your style, but simple to use.

V3 brings all those years of work and testing and failures into a PS action pack that lets YOU create Platinum, Cyanotype, and now Wet Plate.

Go create your looks now. Whether you publish digitally or print on art and rag papers for astounding signature wall art. Your result will be authentic and amazing.

What makes Seim products different?

Everything here is created by a Master photographer, not a marketing agency!

When you use good formulas and craft tools, you create better results because you waste less time. A lot of people diss tools like mine because they say they only use their own recipes.

That's like saying you should only use one film because you need to create everything yourself. Or that it's cheating to use your special lens because it gives you THAT look. Professional photographers use Seim tools. Why? Because they make you more creative and give you more control, guaranteed!

As a PPA Master Photographer, I'm always challenging myself to create better. That's how every tool I make starts out. With a hunt for better edits for my Light Tribe community.

You're rightly skeptical. That's why all sales are NOT FINAL here. I guarantee my tools and workshops and I'm confident my products they will become the ones you use and love.

Buy any of my products and try them for 7 days. if after that you feel dissatisfied, send me an email any time within 31 days of your purchase and let me know the problem. I'll fix it, exchange it, or refund your money

I'm Gavin Seim :)

Glad you're here.

I'm from WA State USA and started studying photography in 97. I started work as a pro (using that word loosely because I sucked) using film at age 16. I learned fast but was not as easy to find training then. Sometimes I just beat my head against the wall until I figured stuff out.

As digital came, I went all in and got to study with masters like Ken Whitmire. In 2009 I founded the Pro Photo Show podcast. I started promoting tone-focused editing and when Lightroom arrived, I started developing presets, Styles, Photoshop Actions and photo courses to make editing and workflow easier.

20 years of study and photography in the trenches earned me a Master of Photography (M.Photog) from PPA. I got to see my workshops and tools featured in publications across the industry. Once I even won the prestigious HotOne award for my "EXposed" light and tone workshop. But I learned a degree means nothing, results are what count.

Wanting something calmer, I moved to Mexico with my family in 2017. It's a land of magical light. I'm here now exploring light and trying to master my weak areas. I make videos of that for my Light Tribe YouTube channel, sharing what I learn. 

I hope you'll stick around and be part of Light Tribe... Gavin Seim
