Pairings describe the dataset and do not establish a complete compatibility list.
Bars show photo-weighted frequency. The table separates photo counts from photographer-balanced share.
Photographer-balanced share gives every professional photographer equal total influence
across a distribution, then reports the percentage assigned to each bucket. This reduces the effect of
unusually large portfolios.
