Clean and great!

I am so proud of my time-lapse photography after I use this app.

• 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.
