Disable DOF in enhance

Disable modification of ray origins in enhance mode. Renderman still thinks DOF is enabled, so focus factor will apply to geometry tessellation, but DOF-related blurring will not occur. This option and the one below enable you to get a fully accurate enhanced view of the geometry, without lens effects obscuring it

Disable Motion Blur in enhance

Disable distribution of samples over time in enhance mode. Renderman still thinks motion blur is enabled, so motion factor will apply to geometry tessellation, but blurring due to motion blur will not occur.

Adjust differentials in enhance

Should enhance mode use the ray differentials of the un-enhanced image (unchecked), or adjust them to reflect the smaller size of each pixel in the enhanced image (checked)? The former shows the true contents of the un-enhanced pixels, the latter lets you resolve
