ND フィルター.
ND 倍率または段数を新しいシャッター時間に変換します。
The new time is the base shutter times the factor. One stop is a factor of 2. Optical density is log10 of the factor. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
- Factor
- 1,000
- Stops

- New shutter
- 10 s
One stop doubles the exposure. The new shutter time is the base time times the ND factor. Optical density is the base-10 logarithm of the factor.

Convert an ND factor, stop count or ND number into a new shutter time and optical density. The new time is the base shutter times the factor. One stop is a factor of 2. Optical density is log10 of the factor. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
ND 1000 on a 1/100 second shutter.
