Does an open iris mean more contrast?

Or does the contrast not change at all if I film with f2.8 and ND filter or f11 without ND?
 
An OPEN iris will allow the maximum amount of light to enter the lens and does not necessarily change the contrast of the image, which is to say that the difference between the lightest and darkest parts of the image will remain the same for the most part regardless of how much light is entering the lens.
 
wide aperture = more light going in + shallower dof
smaller aperture = less light going in + deeper dof
