You’ve heard about it for sure! The Hyperfocal distance is one of the most mysterious and sexiest-sounding photographic concepts. Basically, it comes for the lens and the aperture to maximize depth of the field. Or Use it to ensure that everything in the scene will be sharp at the smallest aperture number. How to do it?
Depth of field
First let’s explain the concept of Depth of field. It tells us what part of the scene will be acceptably sharp and what will be already blurred. The closer object we focus, the depth of field is smaller. The lower the f-number set, it will again makes a smaller depth of field. And last but not least, the shorter the focal length of the lens, the depth of field will increase. So three factors enter the game and influence each other.
Hyper focal distance
The theory says: If you focus at Hyper focal distance (H), there will be sharp everything from H / 2 precisely to infinity. You’ll then have a largest Depth of field. It works given aperture and focal length.
Hyper focal distance is useful in the landscape photography to make sharp objects in both the foreground and background. Judge the distance from camera to the nearest object. Focus on twice distance. Set correct aperture and you won!
How to determine Hyper focal distance?
The calculation works with the focal length and aperture. The formula is not important because it is impractical to calculate the scene. Some photographers using Hyper focal charts or graphs. It is impractical and complicated process. So, we made a useful mobile app that will calculate the Hyper focal distance on the iPhone or Apple Watch. It does not need an Internet connection, so you can use literally any time.
Using is very simple: Set focal length based on the lens you use. Then make sure you set the size of the sensor correctly. Finally change the aperture and see immediately what comes Hyper focal distance. You can also save the obtained value.
