Filters: B+W 103 0.9 ND, 3-stop neutral density

Graphs are in nanometers. Visible light is approximately 390 - 650 nm (the human eye can see very weakly into the 700-800nm range). Graphs used by permission of Coastal Optical System.

Spectral transmission — B+W 103 0.9 ND

While B+W calls it a “neutral” density, shooting a neutral gray card for white balance would be wise because the spectral response is not entirely neutral (totally neutral doesn’t exist for ND filters). Images tend to be slightly warm (yellow).

For visible light shooting, only the 400-650nm range is relevant below.
