Description	Over the past decade, diverse observations of the Sun, corona, and heliosphere during solar minimum have repeatedly shown that the solar wind expands radially from the entire Sun. These results are, however, at odds with the conventional view of superradial expansion from polar coronal holes. The purpose of this Letter is to reconcile this conflict by taking a closer look at solar eclipse pictures on which the conventional view is based. The latter are referred to as processed solar eclipse pictures because they are obtained with a radially graded density filter or by the merging of images taken at different exposures and subsequent numerical image processing. We illustrate the importance of quantitative studies in understanding imaging by comparing numerically processed images and isophotes from the 2006 solar eclipse. Familiar large-scale structures traditionally interpreted in terms of density as diverging polar coronal holes and converging coronal streamers are in fact features of differenced dens Over the past decade, diverse observations of the Sun, corona, and heliosphere during solar minimum have repeatedly shown that the solar wind expands radially from the entire Sun.
