DoF Viewer is an application used to calculate the depth of field (DoF) as well as the Angle of View (AoV).
It also calculates the hyperfocal distance, the near and far boundaries for acceptable sharpness (near focus and far focus).
A new function gives an indication of the amount of background blur.
The application is Universal, it means it can run on both iPhone and iPad.
The originality of the application is its graphical interface that allows the user to view
the depth of field values on all the aperture range without having to change a new setting.
The user can quickly realize the influence of its setting, and other possibilities it has to manage the depth of field.
The application is very simple to use, only two parameters require configuration:
- The type of camera used (A database of over 250 cameras is available)
- The unit of measurement (metric or imperial)
The user configures its shooting parameters with 2 "sliders".
- The focal length (focal) between 8mm and 1200mm
- Distance shooting (Distance)
The depth of field is calculated in "real time".
Thanks to a "moving" window, DoF Viewer gives the value of the hyperfocal, the depth of field (DOF), the minimum and maximum distance of acceptable sharpness zone (Near Focus Far Focus) for each f-stop.
And this without any button! Simply with a "vertical" swipe on the workspace.
A «tap» on one of the DoF row will display the new view : The visualization of the amount of background blur (or degree of fuzziness ). With this new graph you can analyze how blurred areas are represented on the picture and estimate both the degree and the quality of unsharpness. The graph represents the variation of the blur spot size in function of the distance.
A "Tab" provides access to the calculation of the angle of view
The angle of View is given in degrees it represents the angle covered by the lens (horizontal, vertical and diagonal)
The field of view is given in meters (feet) it represents the distance covered by the lens for a given distance.
Another view is used to display the depth of field in another way!
This "bar graph" view shows the depth of field for the entire range of f-stop
The user can configure the aperture scale from of f/1 to f/64 with full-stop, one-half-stop and one-third-stop f-number.
The distance scale is also configurable to suit the type of lens used (wide or tele)
Beware though it is possible to configure a 1200mm lens with a focusing point at 5 cm, DoF Viewer does not check the consistency of the parameters entered by the user!
An "Expert" mode is available to calculate the circle of confusion
This calculation eliminates the criterion of Zeiss and can estimate the depth of field with respect to the final image (enlargment).
Help section explaining the concept of "expert CoC" is accessible from the application
With The iPad version it is possible to compare two different types of configuration
After researching other DoF apps, I found DoF Viewer to be much more detailed and useful than the others:Pros: I love that you can see a comparison of DoF for all f-stops simultaneously. I also love the field of view page to see exactly how much of a scene you can capture from a given distance using a particular focal length lens on a particular camera.Cons: The focal length bar graph showing the "in focus" range is useful in general but doesn't appear to be accurate regarding how much distance is in focus (green) in front of the subject vs in back of the subject, though the numbers appear to be accurate. The histogram graph is a bit confusing...I'm still trying to understand it's usefulness. Also there appears to be no way to contact the developer regarding bugs or feature requests. Other than this I absolutely love this app and would have gladly rated it 5-stars!
DOF and HFD Done Right
Windfola
This app has been out for three years and has been revised through version 3.1. I am surprised that there are only 13 reviews. This is a great app, well designed, and quickly provides DOF and HFD analysis at varying field conditions. The graphical summaries are fantastic and the Expert CoC calculations appear to be well done. The Help summary of CoC is very good. I would recommend this app to any photographer wanting to develop a better understanding of DOF and HFD. The iPad is the best; easy to manipulate and view, great graphic and human interface design, and flawlessly uses iPad real estate. The iPhone implementation is limited by smaller form factor but still accomplishes most of what iPad does.Recommendations: iPhone, not able to set up Camera2. Having a reference camera is quite useful. iPad and iPhone: (1) suggest using decimal ft for Imperial units, switching to decimal inches at distance less than 3.0 ft, (2) provide better description on proper focal length to use on DX size sensors [lens FL = 18mm, effective FL = 28mm at crop factor of 1.5, which to use? I believe 18mm is entered and calculations adjust for sensor specific crop factor. Clarification would help.] Easy 5 Stars.
A Bargain!

I'm impressed. All the information I want displayed professionally. I have purchased 4 depth of field apps, several which cost at least twice as much, searching for the "right" app for a person who owns multiple cameras. This is it!I do have a request. Please add support for the Nikon 1 V3.
Plenty of info, well displayed

This app tells you an awful lots about focus parameters, and does so in a very professional way. You can set up 2 cameras so that the app has a basis for its calculations. Cheap at this price.
