chromatic aberration

[glorybound]

Are you guys still doing chromatic aberration? How are you doing it? I stopped years ago, but I might want to try it again, but I want it easy. All the PS actions I have tried way over do it. I had this, but they are not developing it anymore and all their links are dead. http://arionfx.com/arionfx-for-photoshop

I found this, but it causes havoc in my images - https://graphicriver.net/item/3d-ren...tions/18588252

Load a map in your physical camera and you will get CA in your renders, this way it will work properly with DOF too.

[glorybound]

Can you elaborate?

[sirio76]

Just load an aperture map in the physical camera.
Here is an example with and without the map:

[glorybound]

I am using MAX, so I'll have to see if that is supported. I don't think it is.... Thank you!

[Joelaff]

Yes, I use this a lot in Max. It’s in the VrayPhysicalCamera settings. Bokeh Effects->BitMap Aperture.

Note there is a bug where Depth of Field is turned off if you enable the BitmapAperture checkbox but do not load a map into the settings.

[glorybound]

Any resource for the map to use?

[sirio76]

You can easily build it by your self in PS by layering R G B with a slight offset in additive mode, you can give any shape you want.

[glorybound]

I have tried everything and I have yet to get this to work.

[Joelaff]

Make sure you have DOF turned on. You really only see it in the out of focus areas. It is not a full CA solution, but it is better than nothing. It does render a hint slower, though.

[glorybound]

Maybe it is working an I just can't see it. I'll post this when it is done. THANK YOU!

I'm working a lot for removing chromatic aberration of the pictures I take out in the nature.

Anyway, is there a recommendation for the resolution for the source picture? Does it have to match the rendering resolution?

[sirio76]

No, even a 512pixel bitmap will do the job

Bobby, did you get it to work?
Here is a tutorial about how to do it, as well as aperture maps you can use:

Chromatic aberration will only show up in your DOF though and not the focused parts of your rendering. I think the easiest way to create CA is Photoshops Lens Correction tool, but it is the same in all places in your image, not like a real cameras CA where it mostly is seen closer to the edges of the phot.

[glorybound]

I didn't, so I'll check it out. Thank you!
