Inverso

Inverso helps you make exposure corrections in film photography and corrects for bellows extension and film reciprocity failure. It does this not only for continuous light, but also for flash exposures and combinations of flash and continuous light.

The exposure time and aperture are corrected for filters, bellows extension and film reciprocity failure. For those hard to time long exposures, a timer function is built in. This timer function has optional delayed start, audible beeps and warnings for when the exposure time is about to end. This keeps your hands free to work the camera shutter and you no longer have to count out the seconds.

The film reciprocity failure relations are included for most films that are commercially available in sheet film. For these relations, reliable sources are used and the user is warned if the data is extrapolated or not reliable. Regular updates will be made to extend the database or update already available data.

Are you a pinhole shooter? Then Inverso is also for you! Since version 1.3 a special pinhole mode is included that allows you to use all features available in Inverso, without having to do complicated conversions yourself.
