Take control with authentic Platinum and darkroom emulsions!

I'm Gavin Seim and my career started with film. I moved to digital but returned to film and started to connect it to digital in new ways. I became passionate about the magic of silver and early era emulsions like Platinum and cyanotype. I said.. "Wow, I'm going to make that for digital." The result is the emulsion system for Photoshop.

My emulsion action system is my most popular among photographers who want to create artisan gallery quality B&W art.

This is an action pack that lets you create iconic darkroom like emulsion tints like nothing else. It started when I saw traditional platinum prints at an exhibition

What actual Emulsion users are saying...


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

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

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

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

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.

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?

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. I started promoting tone-focused editing, then I started developing presets, Styles, Photoshop Actions and photo courses to make our photography better.

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.

Everything here is lovingly crafted by a photographer, not a marketing agency! You're rightly skeptical on online photography things. That's why all sales are NOT FINAL here. I guarantee every one of my tools and workshops 100% with my 31 day IRON Guarantee!
