Infrared colors, polarization wavelength dependence and criteria for cluster membership are used to examine the interstellar extinction law in the Orion region, in light of 0.36-0.82 micron linear polarimetry and infrared photometry observations of stars within a degree of the Orion Nebula. The stars inside the dust clouds are examined on a star-by-star basis, and the different intracluster grain size indicators are found to be in excellent agreement. Normal radius and maximum wavelength values of about 3.0 and 0.55 microns are observed in stars lying outside the two main regions of nebulosity, indicating normal grain sizes. For a carefully selected group of stars inside the nebulosity that is characterized by extinction by large interstellar grains, the circumstellar emission does not significantly affect the values of R derived from the V-K and V-L colors.
