  We present high-resolution, high dynamic range column-density and
color-temperature maps of the Orion complex using a combination of Planck
dust-emission maps, Herschel dust-emission maps, and 2MASS NIR dust-extinction
maps. The column-density maps combine the robustness of the 2MASS NIR
extinction maps with the resolution and coverage of the Herschel and Planck
dust-emission maps and constitute the highest dynamic range column-density maps
ever constructed for the entire Orion complex, covering $0.01 \, \mathrm{mag} <
A_K < 30 \,\mathrm{mag}$, or $2 \times 10^{20} \, \mathrm{cm}^{-2} < N < 5
\times 10^{23} \,\mathrm{cm}^{-2}$. We determined the ratio of the 2.2 microns
extinction coefficient to the 850 microns opacity and found that the values
obtained for both Orion A and B are significantly lower than the predictions of
standard dust models, but agree with newer models that incorporate icy
silicate-graphite conglomerates for the grain population. We show that the
cloud projected pdf, over a large range of column densities, can be well fitted
by a simple power law. Moreover, we considered the local Schmidt-law for star
formation, and confirm earlier results, showing that the protostar surface
density $\Sigma_*$ follows a simple law $\Sigma_* \propto \Sigma_{gas}^\beta$,
with $\beta \sim 2$.
