Depth of field is often misunderstood, especially when it comes to what actually affects it and how you can change it through the technique you use. This video shows you everything you need to know about the physics behind depth of field.

This great video was made by Gerard Undone and teaches you everything about depth of field and what actually affects it. He also shows you an easy way to think about the physics behind it.


There is quite a bit of confusion about how depth of field actually works and how you can really influence it. Good knowledge and understanding of this is crucial if you want to work well as a photographer and use your technical knowledge in a way that helps you achieve artistic results.

In the video, Gerard talks about the 'entrance pupil'. This is the image of the aperture as seen from the front of the lens, also known as the effective aperture.

You can think of it as the aperture after it has been affected by the magnification of the blades in front of it. It is a great video that can really help you to better understand a common and often misunderstood subject, so give it a watch!

    This gentleman speaks so quickly and agitatedly that it becomes unpleasant to listen to him, let alone understand him properly.

    I agree. After 1 minute, he had already lost me.
    Too bad,

    My English is pretty good, but I find the way this man talks really irritating, so I too lost him pretty quickly
