Beyond Camera Basics - Focal Length

So here it is, the first in a series of videos called Beyond Camera Basics. My goal is to go through concepts of Still Photography and Cinematography that seem basic and easy and show that there is much more to these concepts then you might think. For the first video we will be going through Focal Length, possibly the most fundamental part of photography.

Do you know what focal length is? What is it measuring exactly? What is focal length actually referring to? Well this video will go through it all and explain in as simple terms as possible the science behind focal length. Learn about what it is as well as what it can do for you and how you can use different focal lengths to your advantage. 

This video starts at the basics assuming you have almost no knowledge of focal length and goes up to into advanced concepts that many have probably never seen. So even if you know about focal length already, there will probably be some info in here for you.

And all of this in a quick 10 minute video. Check it out!

For those of you looking for more info on the subject, here are a list of my references for this video. There is info here that I could not fit into my video, so I encourage you to do more research on your own if it interests you. If you have any questions that were not answered in the video, leave a comment and I'll try to clear things up for you.

Thanks for that interesting video. I now have a better grasp of the concept of focal length and how different prime lenses give different angles of view based on the image sensor size. I am also interested in understanding how the flange focal length affects the angle of view. It's my understanding that the flange focal length is important in determining the accuracy of focus measurements in a lens.
