Degraded images synthesised from an MHD simulation at a continuum wavelength near 6300 Å for different values of r0 (mentioned in the panels). The grey scales of the degraded images are identical. The grey scale range of the undegraded image has been enlarged to avoid extreme contrasts. The sampling in all images is 0.044″. Top left: undegraded image (no added noise) corresponding to r0 = ∞.
