Mosaic: Photographs have been cut and mosaiced onto cardboard backing.

Original Image Condition: Variable. Most of the paper prints are well-preserved, with minimal discoloration or staining. On many frames, beaches are overexposed and do not show many features or texture. Photographs were mosaiced at an unknown date. No documentation is available stating if a study was published using these images. Scanned images are shown with part of the cardboard backing.

Scanner: UMAX Powerlook 2100XL

Resolution: 600 x 600 dpi, 256 Gray Scale

Supplemental Information: These files have not been orthorectified or projected. The images are numbered sequentially from west to east, Fire Island first, then proceeding east to Saltaire. Identification label shows: VI 876K 97th)(8-20-37-11:55A) (12-8400) FIRE ISLAND COAST EROSION. This indicates use of a 12-inch lens at 8,400 ft altitude.

Contrast adjustments: Total tonal range based on the histogram of pixel intensity for overall photographic image (backing and borders excluded). Typically, the low, mid, and high values settings were set automatically by software.

Note: Some images appear dark when viewed on the computer screen, but the original prints were scanned to emphasize beach features for the purpose of shoreline mapping. We have tried to retain textures on the beaches.
