Calculate the required white balance settings for an image made with a high-density ND filter with a known shift.
Calculator for depth of field and equivalent lenses on various camera systems.
This is an attempt to present an alternative to the normal view of “resolution” by looking at how diffraction impacts the maximal resolving power at a given aperture.
Calculate the difference between two exposures (shutter speed, aperture, and ISO) or any two shutter speeds, apertures, or ISOs.
Calculate the mired difference between two light sources. Calculate the filter necessary to convert from a light to a given color temp film, or to correct for another filter.
Calculate the minimum resolution required for a print at a given print size and viewing distance.
