Getting breathing out in post is difficult takes away valuable time that you could spend making good looking vfx ;)
I believe there are sections on lens design and theory, plus the causes for "breathing" problems in focus changes in past editions of the American Cinematographer's Manual -- a must-have publication that every DP should own.
"Breathing" is a term used to describe the apparent change in the field of view while racking focus. It's an optical-mechanical design flaw. It's much more expensive to design a lens that does not breathe. A "floating element" is a very common method for correcting breathing in a lens. Most still photo lenses will breath a since manufacturers such as Nikon and Canon don't really care about making the image as accurate as possible. Can you tell the difference between a 45° field of view and a 46° field of view looking through your view finder? Probably not and nobody cares about a 1° difference when you snap a still frame. But when the field of view changes while focusing during a continuous shot, it's devastating to the scene. Watch Super 8 and look for the long focus pulls from infinity to close focus. The breathing exhibited by the lenses in that movie is horrible, made even worse by the anamorphic lenses. Cinema lenses do their best to reduce breathing and in most modern lenses, accomplish this very well. Try to find some breathing in a set of Master Primes. ...Good luck.
For example, keep an eye on the right edge of the frame as i run through focus. Sorry about the shaky image, this was a quick and dirty example.
Matthew you tucked my words out of my mouth and bit me to it... ;)
Oh and if you would to see the Leica Summilux C. Primes, you would be very impressed as well, Absolutely NO breathing on those babies, but you do pay, as their cost is in line with the Master Primes...
You do pay for what you get when it comes to asking NO BREATHING in Cine Glass, for Still Glass, well deal with it, as it isn't going away,
and for this I say don't use still glass in 3D, it will make your life existence MISERABLE!!
That leads me to ask why do you think that some major directors and DOPs prefer UPs over MPs.
If it's not a money issue, I've never heard anyone turn MP's down for UP's unless it was a hand-held or steadi-cam shot/shoot. Who knows. I have plenty of UP experience, but don't get the MP's too often, so I'm not knowledgeable enough to really know the difference the two give in look to guess the aesthetic preference.
Yeah...i mean, i think i saw Peter Jackson chose UPs in Lord of the rings.
Maybe i'm wrong but i think i saw that on BTS pictures.
