Description

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.

Recent changes:
• Refreshed look
• Improved filter management
• Light & dark app themes
• Dynamic colors

Comments on Bellows Factor for Android

★★★★☆ Charles Twist · Oct 21, 2017

Excellent app! Would love another line with exposure compensation factor, ie 2 to the power of the returned value. I can't calculate that in my head, unlike f/stop minus value, Thanks!

★★★★★ Curtis Nelson · Jan 25, 2023

Very nice unobtrusive little app. No ads! I like that the exposure factors are displayed in EV - this pairs very nicely with my spot meter when calculating exposure. Thanks!

★★★★★ David Hancock · Mar 31, 2017

Exceptional tool for large-format photography and some medium-format photography. Highly recommended.

★★★★★ Phillip Summerlin · Aug 22, 2021

Does what it says. Simple and easy to use.

★★★★★ Stephen Migol · Nov 3, 2022

Easy to use in practice and has helped nail exposure with film that doesn't have a lot of latitude.
