filter factor मीनिंग इन हिंदी

The table below gives approximate filter factors for a variety of common photographic filters.
Thus, filter factors provided by the film manufacturer should be preferred over the ones documented below.
It is important to note that filter factors are highly dependent on the spectral response curve of the film being used.
The table below illustrates the relationship between filter factor, the amount of light that is allowed through the filter, and the number of stops this corresponds to.
As a consequence of this relationship, filter factors should be " multiplied " together when such filters are stacked, as opposed to stop adjustments, which should be added together.
