DoF

Penerangan tentang DoF

Ever wanted an easy way to find out what aperture to select to get the right depth of field?
Depth of Field is a measurement of how blurred the background looks, the shorter DoF the blurrier. You have probably seen a portrait where the eyes of the model are knife sharp and the ears are a bit out of focus, and the background has a very soft blurriness. How big the range is that is in focus is ruled by the focal distance you use, what aperture you have chosen, the distance to the subject and a parameter in your camera called circle of confusion. Then a rather complex calculation needs to be done.
Many photographers carry cards with a chart when they are selecting the values to get a certain depth of field. DoF can do that for you. For example if you know how far it is to the subject and what focal length you use, DoF can calculate what aperture you should use. Set that, let the camera select the time and you’re done.
DoF will also calculate the hyperfocal distance, this is the distance you should set your camera to, to get everything to infinity look sharp. If you like, DoF can calculate what guide number your flash needs to have, or how far it will reach.
DoF is really easy and intuitive to use and has an extensive help included. DoF includes information for circle of confusion for 1235 different camera models, if your camera is not found, you can enter the number manually, or adjust a predefined value.
You can select whether the aperture values should be selected, and displayed, in full, half or thirds step. All your selections will be remembered even when you close the app.
Dof is not in any way connected to the camera in the phone.
DoF is localized to English and Swedish.
DoF calculates these parameters:
- Total Depth of Field
- What aperture to use for a given depth of field
- Hyperfocal distance
- Required guide number
- Distance the flash reaches
- Depth of Field in front of subject
- Depth of Field behind subject
DoF runs in three different modes:
- Depth of Field and Guide number
You enter:
Focal Length
Distance
Aperture
ISO

DoF is an excellent tool to calculate for example depth of field or aperture.
DoF is an excellent tool to calculate depth of field from the selected settings of your camera, it can also calculate what aperture to use to get a certain depth of field and number of other parameters.
