Yeah! This article is great, and it's an EXTREMELY important concept that underlies and informs the very process of image creation. When I discovered this fact about compression (not that long ago!) it completely changed the way I scout, frame, compose, and shoot. All this even after 10 years of regular photography/cinematography practice. Thanks for sharing!
I roll them inside paper towel cardboard tubes and stand them up in a milk crate.
Love my G7. My single complaint is that it's too easy to accidentally bump the thumb-wheel. Otherwise it's a perfect camera for me and the value is just mindbogglingly high.
For the sake of filmmakers still wrapping their heads around this concept, I think it's critically important to be very conscious of word choice when describing what changing focal length actually does, because the decision to move the camera or change focal length will be decided by what you think each does (as the video gets at). This was a trap I was stuck in for a long time.
"It might be easier to just give your zoom ring a quick twist, but it will drastically change the look of an image: it will crop it, flatten it, and change the size of background elements."
Let's be 100% clear here: zooming ONLY crops the image (as the video says). It does NOT flatten or change the size of the background elements. The only thing that creates compression between your subject and the background is the position of your camera relative to these things, i.e. your perspective. Zooming just changes the field-of-view captured of the perspective your position provides.
Now, it's convenient short hand to describe zooms as compressing, but it's only true when comparing a change in focal length AGAINST a camera move that gives you equivalent FOV of your subject.
Why I think this is crucial is that if we teach young filmmakers and photographers that zooming "changes" the image (flattening, compression, etc) then it imparts a somewhat nebulous or magical transformative property to the camera/lens. Thus, your camera/lens choice become key players in the crafting of your composition.
This is NOT true, and forces an encumbering dependency on your camera when building your frame. Instead, we should be teaching folks to use their eyes and their feet to find the shot they want. Where your eyeballs are is what the camera will see (perspective wise), then you choose the lens (and/or sensor/film size) that crops the FOV to what you want to include in the shot.
That's it. The lens and camera have no impact on the perspective if you have access to the focal length that gives the crop/FOV you want. So use your head (and eyes, and feet) first, then set the camera up. It'll make the whole process easier, faster, and open up a world of possibilities because you won't be wondering in the back of your mind how the lens/camera will change the scene.
There was a video posted on NFS a few months ago that showed this in a studio by cropping in post vs. zooming.
The rule I lead by is: "It's only a mistake if you do it twice. The first time is just how we learn."
The tricky thing with a feature is that for it to be "good" from a technical standpoint you're likely going to spend 6-12 months working on it, but without experience in the entire filmmaking process you may find halfway through that you don't actually have a thematically/narratively "good" film. Or that the project has changed from when you started because of everything you've learned along the way. These are the reasons you'd want to wait.
However, as far as a small crew, this really only limits the type and scope of films you can produce. For example, I co-wrote and co-directed a mockumentary which will likely come out at between 60-80 minutes that was mostly improvised with non-actors, and shot almost exclusively on a Canon EOS M in Auto by a non-experienced camera operator. However, because we knew going in that we only had access to these "limited" resources due to time constraints, we designed the film around the limitations by making it a student film mockumentary, etc. Then the limitations because texture for the narrative.
