A handy application for advanced photographers
Bellows Factor can help you to achieve better if not perfect exposures with large format cameras.
The basic operation includes calculating the bellows factor in EV based on your focal length and lens extension. These values can be inserted in either millimeters, centimeters or inches depending on the lens or the photographers' preference. But that’s not all. Bellows factor can be combined with any number of filter factors so a correct exposure factor is computed based on the lens extension and filters used.
The Bellows Factor application comes with the predefined set of well known photographic filters and their EV factors that you can modify and customize based on your own collection of filters because we know, that every photographer has their own selection and favorite combinations of filters.
