Contact sheet
From The Glossary of Digital Photography
A number of images, usually small, on one sheet or page. The term came from the analog (film) photography era, when the negatives from one roll of film were laid onto a sheet of enlarging paper so that many images could be seen at the same time. When digital came about, the concept was still useful, so sheets of thumbnail-sized images are still often called contact sheets. With software such as Photoshop, the size and number of images on a sheet can easily be changed, unlike the film days, when the size of the images was usually the same as the negatives. Sometimes the contact sheets are bound into a book for presentation,
such as for a wedding client.
