The camera world is never simple. Never at all. Nowhere else is this more apparent than when you consider lenses, sensors and how they’re used. What’s so easy to forget is that they’re complicated devices that require precise engineering.
The centuries of engineering and science that’s gone into modern optics should never be discounted, and this video, posted by FilmmakerIQ explains exactly why we shouldn’t be taking it for granted.
What’s so interesting about this video is about how much science goes into the basic information of the lens world. Things like apertures become ingrained into your head after you’ve shot long enough, and when that happens you tend to forget they ACTUALLY mean something.
The science and methodology behind the numerical system of apertures was very enlightening, as was the explanation of T-Stops, which I thought I understood.
Hearing what John Hess had to say about it further showed me just how important the T-Stop is to the cinematography world.
Also I love that he discussed the Split-Diopter. Very few people in the photography and cinematography community nowadays even remember that these exist, let alone their use. While I don't really like the effect they have on a picture, it shouldn't be forgotten.
Not only has John Hess and FilmmakerIQ given all kinds of great information about lenses, they’ve gotten me excited about experimenting with them again. Now I want to go back to school and learn more about optics.
The Properties of Camera Lenses
FilmmakerIQ's Introduction to the Properties of Camera Lenses
John P. Hess, over at FilmmakerIQ.com has launched a second video about lens technology this week. This time dealing with the properties of camera lenses. The information contained relates to both still photography and cinematography, and also details the subtle differences between the two as they relate to lenses. He covers topics such as focal length, aperture (or iris), the differences between primes and zooms, and even a look at anamorphic and parfocal lenses.
