Lesson 23 – DoF Calculator and Hyperfocal Distance

In this photography lesson we will be learning about Depth of Field (DoF) and how to calculate it knowing aperture, focal length of the lens and distance to the subject. We will also talk about Hyperfocal Distance.



Depth of field Calculator: Depth of Field Calculator

Depth of Field (DOF) is the distance between the nearest and farthest objects in a scene that appear sharp/in focus in an image

Depth of Field depends on Aperture, focal length of the lens, distance to the subject and also size of camera sensor

Hyperfocal Distance

If you focuse on the hyperfocal distance, everything from half the hyperfocal distance to infinity will be in focus.

    Hello, It was just recently, that I found your websites and your photography tutorials. I am delighted by what you offer, that is free no less, and, the easy going manner in which you simplify the process of photography. My exposure to photography began back in the eighties where I was mentored by two different photographers; one was a portrait photographer who was strictly a Hasselblad man. The second was a product photographer who was hired by companies to shoot their products for them. Of course this was in the days of film too. I stayed with it for about two years, and then got into Harley Davidson motorcycles, and that ended my affair with photography until just recently, when upon receiving a large settlement, I acquired a full professional line of camera gear; Canon D 5 Mark II, Tamron 24-70 lens with image stabilizer in f/2.8, Canon 70-200 II with Image Stabilizer in f/2.8, an older albeit reliable flash, Canon 550 EX with a diffuser, pro tripod and monopod, and two very nice camera bags; one large and one small. It is my intent, already having a background in photography, to get up to speed with my camera and, digital photography, so as to allow me to create professional images, worthy of much attention. Oh, and by the way, I still am into Harleys, but now I am able to capture the lifestyle in a way previously not possible. I cannot possibly thank you enough for what you do for so many like myself, who not having the ability to go out and spend large amounts of money on photography classes, can find such a awesome person as yourself, so willing to help others out. I wish you and yours the very best life has to offer.
    Regards, G
