What Emulsion users are saying...

Switch tones, create advanced atmosphere, thin your bath, re-mix.

I took this photo and did 8 different chemical edits in a couple minutes. Every emulsion and tone you apply in Emulsion 4 has an out-of-the-box look. Then you can insanity adjust tint intensity with the intelligent master tint layer. Or mix it with gold dust mods, and other instant layers. Or do a re-mix with 1-click. Even real paper and texture that uses select seamless variants from Naked Darkroom.

In version 4 everything is simple - Run the master action and get the Classic Platinum look. Switch it to any of the other tones, or you can mix them up to create a more complex atmosphere. Don't like what you see, with a click you can reset and keep playing.  Emulsion 4 lets you tone and mix without limits as if you have the actual chemicals in your own darkroom.

Perfect folios and prints

With modern digital prints, we can have true monochrome. But that can be sterile. In the real darkroom, different chemicals produced different tones, shadows, and complexity. Emulsion 4 re-creates that.

If you only want pure monochrome my BlackRoom system is perfect. But if you want black and white that goes further... Rich natural chemical tones that are created from the darkroom, Emulsion is your new favorite tool.

Emulsion 4 is based intense study of each early chemical mixes. Whether tones and details of a wet plate. The classic ratios of a Selenium bath. The dimension shadows created in the Platinum and Pallidum process.

Color grading and RAW split toning can't hold a candle to this. Emulsion 4 creates an atmosphere and authentic tone. Because you want to give the most authentic result possible in digital processing.


They rock!

I very much like your pre-sets and actions. They rock!

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

Richard Man

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

quite pleased...

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

Ernst Ulrich Schafer

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.

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.

Your iconic platinum has arrived!

The deep 3-dimensional richness of Platinum and other early era toning is not easy to replicate. So Emulsion 4 uses the power of Photoshop and now with a gradient mask toning. It makes tones rich, intelligent and adaptable for every tone in your photo, in real-time. You simply run the action and it gives you all the control you want with no secrets.

They came from the darkroom.

Every look in version 4 system has more authentic darkroom tones sampled from real chemical prints. Thanks to the master tone layer, inspired by the Gradient Mask system of BlackRoom. In fact, Emulsion 4 works great alongside BlackRoom. It even includes the Live tone map from Lumist 2 give you real feedback on what's happening with your light. Use Emulsion 4 by itself, or use it beside our other action packs with smooth integration. 

Advanced edits, even if you don’t know Photoshop!

Emulsion eliminates the limitations and slowdown of a plugin. It uses Photoshops native tools to master your photo fast. Emulsion 4 builds everything with a click. Then you can just it as needed and add mods like tone and variants with another click. Even paper textures and water stains are easy. Emulsion 4 adds the included seamless textures. Because selections from the Naked Darkroom texture pack are integrated into the actions.
