Calculate photographic depth of field and hyperfocal distance
Focus Assistant Pro calculates the depth of field and hyperfocal distance for photography. It also computes the minimum and maximum distances at which objects will be in acceptable focus.
The user interface is friendly, efficient, simple, and attractive. A "scroll wheel" design was chosen for its ease of use and flexibility.
Advanced users: you can easily change the "circle of confusion" to suit any special preferences/needs you may have.
