Thank you for watching this video on 25 technical photography terms that I think everyone (especially beginners) should know. Today, there’s so much misinformation about how photography works: the science, theory, and technology behind how images are formed. In this video I wanted to provide not only the definitions of key photography concepts, but how they relate to each other, gradually explaining the photo-taking process as a whole.

This was my first voiceover, so let me know what you thought in the comments below. I plan to continue voicing my own videos now; it’s about time my channel knows a little bit about me.

I’m adding an errors and clarifications segment to my video descriptions because often in my research, certain things elude me.


Lightroom & Photoshop are mis-labeled (at 8:30)
The Pros/Cons for Auto Mode stay on-screen for Shutter Priority Mode (at 9:33)
(for the Pros/Cons for Shutter Priority Mode, read the transcription provided above)


ISO is not an “acronym” but a mere shortening of the organization’s name.

“DOF does not describe the depth of the part of the image that is in focus. It describes the depth of the part of the image in which points are adequately sharp. Only objects at one specific distance are in focus, so the depth of points in focus is always 0. An object in a scene is in focus if all the light from a point on the object is refracted to a point on the image. With an optically perfect lens, this occurs only with points a specific distance from the optical center of the lens. Any points closer to or farther from that optical center have their light refracted into a blur circle on the image. The farther the object is from the distance at which points are are in focus, the larger is the blur circle. When the image is printed or displayed, a blur circle is either so small that the human observer cannot tell the circle from a point, or large enough that that the observer can tell the circle from a point. When the circle is observably different from a point, that part of the image seems blurry. When the blur circle is small enough to be indistinguishable from a point, it is called adequately sharp. The DOF describes that part of the image in which blur circles are adequately sharp. The DOF of an image depends on several factors, including the visual acuity of the observer, the print or display size, and the viewing distance. To promote comparability of DOF between images, standard observer acuity of 6/6, print size of 8″ x 10″, and viewing distance of the image diagonal are often assumed.” – FingerPainter from DPREVIEW
