Calculation method
Calculation method
Total optical density
D=sum densities; T=10^-D; stops=D log2(10).
Transmitted intensity fraction
D=sum densities; T=10^-D; stops=D log2(10).
Exposure compensation (stops)
D=sum densities; T=10^-D; stops=D log2(10).

Assumptions & limits
Assumptions & limits
- Independent ideal absorptive filters, neglecting multiple reflections. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Independent ideal absorptive filters, neglecting multiple reflections.
