A catalog of catalog design- Eye Movement Direction

Silhouette, or outlined, photographs can also be used directionally. Silhouette photos on catalog pages are most effective and believable when a soft drop-shadow is used. This should be planned for in photography shooting, using a white no-seam background and lighting accordingly to get a shadow of grey. The shadow adds dimension to the depiction of an outline shot. Without a shadow, the effect is like a flat paper doll that has been pasted on the page.
