Three different powders were studied by image analysis. Shadow casting was used to generate information on particle orientation. It was discovered that orientation effects can distort the data generated in size characterization studies and as a consequence of these studies it is suggested that, in any image analysis study intended to be used to generate reference data, shadow casting‐orientation studies should be carried out to specify the orientation of the fineparticles.
