Deep Dive on Cullen Kelly’s New Genesis Plugin

March 17, 2026

Explore Genesis, Cullen Kelly's film emulation plugin for Resolve, with tips on negative stocks, development controls, bleach bypass, & more.

Quick Summary

Genesis, Cullen Kelly’s film emulation OFX plugin for DaVinci Resolve, offers deep customization of negative stocks, print stocks, development settings, bleach bypass, halation, and grain – going well beyond plug-and-play film LUTs to replicate authentic photochemical processes.

Why this film emulation plugin feels more like a digital film lab


In the world of color grading, there have traditionally been two kinds of tools: those that allow customization and those that don’t. This distinction has been especially evident in film emulation, where for many years LUTs, grain scans, and similar fixed solutions dominated the landscape.

That landscape has shifted. With tools like Genesis and other emerging solutions, I believe colorists now have a solid foundation that can also be tailored to specific needs through adjustable parameters. Genesis feels less like a conventional plugin and more like a digital film lab – its default behavior already delivers strong results, but its real potential lies in the depth and flexibility hidden within its settings.

In this Insight, we walk through every major section of Genesis, from project settings and negative stock selection through development controls, bleach bypass, printer points, halation, grain, and LUT export.

Whether you adopt Genesis or prefer other tools, understanding the processes it emulates will sharpen your approach to film emulation.


“Of course, Genesis also works as a plug-and-play option, but I think the beauty and the real power of Genesis relies on how customizable and also how robust it is while doing so.”

Rafael Bernabeu has an ongoing professional collaboration with Cullen Kelly. But this is not sponsored content – Rafael approached us wanting to share his honest assessment of the plugin and demonstrate techniques he has developed through regular use. Evaluate Genesis on its own merits.

Key Takeaways

By the end of this Insight, you should understand how to:

  • Navigate Genesis’s full parameter set – from negative and print stock selection through development, interlayer, bleach bypass, and texture controls – to build custom film looks rather than relying on defaults alone.
  • Understand the photochemical processes Genesis emulates – including push/pull development, printer point offsets in negative space, and the difference between negative and print bleach bypass – so you can replicate these concepts with any toolkit.
  • Set up DaVinci Resolve correctly for Genesis, using node-based color management rather than project-level settings to avoid double transformations.
  • Use the interlayer effect as a luminance-preserving saturation control – a type of operation not available in Resolve by default – and combine it with pre-Genesis saturation adjustments for more filmic results.
  • Export LUTs that include operations before the Genesis OFX – by using Resolve’s LUT generator for the full pipeline rather than Genesis’s built-in export.
