Vintage Wollensak Differential Ray Sky Filter No. 6 for Lg Format Lens - $50 (Southwest Reno)

1234

condition: excellent
make / manufacturer: Wollensak
model name / number: No. 6

Featured is one Rare Vintage Wollensak Differential Ray Filter No. 6 for large format photography lenses, circa 1916. Wollensak filters are made of fine imported optical glass and mounted in handspun brass mounts, with three adjusting screws enabling the photographer to secure the filter in perfect plane of alignment to the lens on which it is used. Wollensak filters are hand coated with quality grade color dyes. Filter measures 2 5/8" in diameter and will fit lens mounts from 2 3/8" to 2 5/8". Made in USA.

The Differential filter, or sky filter is recommended for cloud and landscape work. The density of the filter is graduated, therefore, only the upper half of the filter is stained yellow, and the lower half being colorless. The filter is designed to equalize the difference in light between the sky and foreground, so as to hold back the sky while full exposure is given the foreground to show correct tonal qualities.

Filter comes in original hard sided leather case with velvet lining, embossed with Wollensak logo in gold on top.

CONDITION:
Excellent clean vintage condition with minor wear. Glass is clean and clear with no visible scratches, however, there is some delamination around the outer edge of the filter near the rim measuring approximately 1/8". While not an obvious visual flaw, it may soften the edges of a photo. From a smoke-free environment.
