Description

• Exposure
Perfect Exposure helps you calculate the exposure time when you change the aperture, ISO, or ND filters.

• Time-lapse
Perfect Exposure helps you plan a time-lapse shot by calculating the shooting duration and the final video duration.

• Stars
Perfect Exposure tells you maximum exposure time to produce sharp stars without trails. It includes the widely-used 600 Rule and 500 Rule, as well as the more accurate NPF Rule.

• Star Trails
Perfect Exposure calculates the angular length of the star trails within a certain period. It also shows an illustration of the actual scene.*

• Depth of Field
Perfect Exposure calculates the depth of field under certain focal length and aperture, as well as the hyperfocal distance.


* The illustration does not reflect the actual position of stars in the sky.
