Bokeh in After Effects

I was chatting with fellow Killa KaliforniaN Mr. Diva the other day who is finishing up a music video for Mindless Self Indulgence and we got to typing bout lens blur in After Effects... I remembered I did some tests for WATS that I never posted online? or maybe I did?! I da know but here they are...

So I shot all the stopmo with a Canon 300d... I did 3d set extensions for my stopmo sets so I wanted the optics to match... So I used similar focal lengths with the 3d camera's to match the 300d.... I also wanted the defocusing and blurring to match... I used the awesome plugin Zblur to generate the depth passes from Cinema 4d and applied the blurs in After Effects...

So i did some tests with the two "lens blur" plugins I had at the time which I thought were the best...

Frishluft "Lenscare"
TinderBox "True camera blur"

These blurs are far superior to anything else that comes with after effects btw...

So for my source image I shot a photo of some Xmas lights....


So thats the original image in focus and then defocused in camera

Now this is the TinderBox plugin compared to the real defocus


And this is the Lenscare blur....


I ended using the lenscare blur... after matching it with the real blur I saved it as an animation preset and used it throughout production...

I will be doing the same once I get the 450d...but I will go a step further and calibrate the blurs for each lens ^ ^
