As I understood, except for shadow and (blurred) reflections, the ShadowCatcher should not influence the picture itself, so why does it render DOF in the area, covered by the shadow catcher object?
I would have expected to have that as an option at least.
It seems that it cannot be turned off.

Also, I found out that using a shadow-only light, the ShadowCatcher seems to have a lower limit for Light intensity.
If itīs too low, that shadow object became completely black in the render (it should have been invisible).

Anyone else noticed this behaviour?
