Bokeh lens and render passes?

[daikath]

I'm loving the bokeh lens, not primarily for the depth of field, but much more for the way it can divide a pixel into three colors when you use the bokeh effect with use bokeh.

But as far as I';ve tried, that effect of mimicking digital cameras way of capturing light, does not seem to appear when I divide the image up in render layers. Is there a way to use the bokeh effect of dividing light into seperate rgb pixel ever further away from eachother as the pixel is ever further out of focus?

I mean this effect, it is more severe then wishful, but it shows you what I mean.

Would really help create a realistic image. I've tried to look for info online, so it probably can't be done. But Ihave to ask.

Well you could render everything separately and get the effect. thing is tough it really depends on what you assume your data is, not everythi9ng makes any sense whatsoever with the bokkeh. LIke we discussed earlier the closer you want to work like reality the less you can separate stuff since its essentially a trick.

Thought experiment: as far as tricks go what would the bokkeh and depth channel have in common? How woudl you be able to do anything with it when everything is already defocused? shouldn't the defocus be applied last on all data?
