Virtual Lens is a tool that simulates the effects and defects of light traveling through a lens.

 

v1.2

Removed versioning of the header to avoid errors on earlier versions of nuke. Tested on nukex 10.5 v2.

Added a black clamp to avoid producing nan values when giving negative values in input.

v1.1

Error fixes and optimization. Added a falloff to astigmatism for smoother results.

 

This tool includes the following features :

  • Haze
    • not a proper in-camera effect but I like it and decided to add it with
  • Spherical Aberration
  • Axial Chromatic Aberration
  • Lateral Chromatic Aberration
    • there's already plenty tools for it so I just picked my favorite one ( i.e. Chromatik by spinvfx and Erwan Leroy )
  • Astigmatism
  • Diffraction Glow
  • Veiling Glare
  • Vignette
  • Halation
    • includes a pretty useful feature that allows to generate halation relatively to the highlights size

 

Supports non-square pixel format.

 

Some example with every filters on :

 

example 03

 example 01

example 02

 

 

 

 

Let me know if you encounter problems or if you think of something to change/add !

Interesting. I am getting black after I plug the node.

Hi Pranjal. Thanks for your feedback. Could you be more specific please? You're getting a black output without turning any feature on? Is there any chance you've had some negative or nan values in your input?

Getting all sort of errors when importing the gizmo in nuke

fl_VirtualLens.gizmo:
Group1.Transform8.filter: Bad value for filter : impulse
Group1.Transform10.filter: Bad value for filter : impulse
Group1.Transform11.filter: Bad value for filter : impulse

Hi Florian! Nuke 10.5v6 here. Couldn't try the gizmo, the program crashes as soon as I load it.

Thanks for warning me of this Octavio. I've updated VirtualLens to v1.2, tested on nukex 10.5v2. Let me know how it works for you now.
