We present a  127 × 63 ‐deg 2  extinction map of the Anticentre of the Galaxy, based on  〈 J − H 〉  and  〈 H − K 〉  colour excess maps from the Two‐Micron All‐Sky Survey. This 8001‐deg 2  map with a resolution of 4 arcmin is provided as online material. The colour excess ratio  〈 J − H 〉/〈 H − K 〉  is used to determine the power‐law index of the reddening law (β) for individual regions contained in the area (e.g. Orion, Perseus, Taurus, Auriga, Monoceros, Camelopardalis, Cassiopeia). On average we find a dominant value of  β= 1.8 ± 0.2  for the individual clouds, in agreement with the canonical value for the interstellar medium. We also show that there is an internal scatter of β values in these regions, and that in some areas more than one dominant β values are present. This indicates large‐scale variations in the dust properties. The analysis of the   A   V    values within individual regions shows a change in the slope of the column density distribution with distance. This can be attributed either to a change in the governing physical processes in molecular clouds on spatial scales of about 1 pc or to an   A   V    dilution with distance in our map.
