Continuum intensity distributions for the solar disk-centre for three wavelengths, as a function of the normalised continuum intensity for the 3D model (thin blue solid line), the 3D MHD model (thin red solid line), compared with observations (thick yellow line). Also shown is the prediction from the CO⁵BOLD 3D solar model (dotted line) taken from Fig. 5 of WR09. The intensity distributions for our 3D models were averaged over all the snapshots.
