Calculate hyperfocal, near, and far distances, as well as Depth of Field values. How to use: 1. Select your camera sensor type or size. 2. Input the aperture, lens focal length, and focus distance. Outputs: - Hyperfocal Distance: The closest distance at which a lens can be focused while keeping objects at infinity acceptably sharp. - Nearest Limit and Furthest Limit: The range within which objects stay sharp. - Depth of Field (DOF): The distance over which objects appear sharp. Explanation: Depth of Field (DOF) is the range of distance in a photo that appears to be in sharp focus. Depth of field is a creative decision and one of your most important choices when composing nature photographs or films. This tool is invaluable for assessing the camera settings required to achieve the desired level of sharpness. Thank you for your support. Visit nitrio.com for more apps for your iOS devices.
