You're welcome... me too, it's a drug !
Wonderful DOF as Image Box Studio says... I don't know how to have this double effect (on the lens image), DOF in front and back. Could you explain it ?

hi rolandb

I'll try to explain, also do not know much about photography but I got my way

1- I activated first dof
2- I adjusted my focus point
3- I applied the same focus value parameters in shallow corona
4- and played with f stop to the point that I wanted

the dof effect applies on both sides front and rear depending on the perspective and the f-stop, I'm not very good explain, but I made a drawing, hope it helps.
or if someone could help, more expert in photography :)

Thanks a lot Pedro, it helps a lot; I made, so far, my DOF with a render pass, and it never gives a real good solution.
Your drawing is ok, it's all understood ! I will soon post a result, thanks a lot ;)

First of all, pmcf1981 nice looking renders:) Was there a lot of cleanup to do in the DOF noise or did it handle well? Being a Corona beginner myself, I'll have to check some settings to sample DOF better.

Second: Doing DOF in a render pass is never a good way to go, so if you have time to wait, as renders usually take a bit longer with DOF, you should wait :)
The problem is, when taking pics/render with DOF, the light is "curved" around objects, or better - because of the size of your aperture (fstop) there are rays shooting out of the camera in a larger area... so it captures more information around the back. The render engine knows that, while if you do dof in post, there isn't any information in the image about the stuff behind the blurred object, so it only blurs where the frontal object would be, without the info behind it... I guess kinda like a pinhole camera, where there's basically infinite depth of field. I've explained the way I understand it... I remember reading about it somewhere but have no idea where...

thanks  matej ... :)

I only make two  render regions in most critical parts but only to accelerate the time, only the first render left overnight the other was around an hour
I think the corona is super fast, dof increases the render time but compared to other rendering engine is very fast and good
