Aperture diffraction intensity and disabling bokeh

Post by Eneen » Sun Jan 24, 2016 1:43 pm

Hi,

Is is possible to change aperture diffraction intensity other then changing aperture size? It is connected to bokeh so it seems it's not possible to alter intensity of glare/bloom without re-rendering.
I also tried to find way to completely disable bokeh, but there is no pinhole lens option. Is there any way to do it?

Best regs,

Best regs,
If you use a large f number in camera settings, this is like using a narrow aperture in photography, giving the result of a large depth of field. And if you also pick your focal point, this will also help reduce all the effects of too narrow a depth of field.

Yep I get it, but I just wanted to:
- disable dof completely (pinhole camera?)
- detach diffraction from aperture
It's pretty important when rendering small things where aperture has large value to keep large dof and when I wanted to add only subtle diffration (more like glow) it's just not possible. That's why I asked.

I don't think you can disable DOF, unless you use an orthographical camera. Indigo is physically based and for traditional cameras you'll always have a certain aperture opening.

Post pro AD can be turned on and off, but I don't think the size can be changed. For that you'll want to export an exr and do it in a program specifically made for these purposes, such as Arion FX.

Good luck :)

Thank you Oscar J. Just diffraction from Indigo looks better then from ArionFX, and one post-production step less of course.... Let's make a with then for such feature!
