Whether you're getting ready to film a scene in the distance, a close up shot with a 50mm focal length or any other various of shots with different lenses there's going to be math involved. While an experienced photographer can typically figure out the math for their shots on the fly, sometimes getting the best shot takes a bit of thinking. Then again you can also use the DoF application as it's commonly referred to in order to figure out focal lengths and other information on the fly.
Keep reading for a screenshot of this simple to use application and a bit more information.
The program operates from a single interface with pop up options for quick focal length, sensor, aperature and distance selections. Much like most WebOS applications the program features a grey background with finger friendly options and pop up menus once those options are selected.
Here's a quick shot from the application:
As you'll notice each option is setup right after one another, making it simple to choose your exact camera setup without having to navigate through various screens. The information then displays at the bottom of the screen without changing to a different display. From the output I was able to see my "near limit, focus, far limit, total distances, Hyperfocl point, % near and % far points.
As I mentioned changing options is also simple via a pop up menu which then lends itself to finger friendly touch options:
Just change to ft, inches, meters, centimeters or millimeters and you'll have new output information auto displayed once again at the bottom of your screen.
Users can also choose to use the Hyperfocal button, this option at the bottom right hand part of the screen allows you to calculate the DOF for your setups hyperfocal distance based on the chosen camera, focal length, and aperture.
I like when very simple applications make complex issues very simple. In the case of Depth of Field (DoF) Calculator that's the exact point, it makes a process simple to execute, especially for beginners looking to learn more about shooting crisp in focus cameras and for professionals who want to take the perfect photos every time.
Currently the program is available via the repository, however the developer has submitted the program to the official App Catalog so you should be able to find it their soon.
