Photography is such a unique
way of capturing light that, if done correctly, you could gather light in many
many different and unique ways. And each one of them would look different even
if you film the same subject.
Today, we are going to talkabout the challenges and rewards of filming using a Super High-Speed Camera. AHigh-Speed Camera is defined as a device that is capable of shooting in excess of 250frames a second. If you are a filmmaker yourself and often makevideos, you do already know the importance of framerates. The usual frame rates used to create ‘natural motion blur’to mimic our human eyes are 24 or 30 (depending on the content). So you dounderstand that almost ten times the ‘usual’ frame rate would make a killerslow motion footage.
Recently, Gavin Free from the YouTube channel ‘The SlowMo Guys’ discussed the challenges of filming using a SuperHigh-Speed Camera. The entire channel, as you can already guess from its name,is dedicated to shoot stuff that happens quickly and then slow it down to aframe rate that humans can perceive. It is so odd to think that many of thesethings may happen to us on a daily basis; but even though they happen right infront of us, we never get to ‘see’ them for real. This primarily happens due toa phenomenon called Persistenceof Vision.
Persistence of vision refers
to the optical illusion that occurs when visual perception of an object does
not cease for some time after the rays of light proceeding from it have ceased
to enter the eye. (Wikipedia Definition)
In simpler terms, it meansthat we humans can only perceive things that are happening at a certain speed;anything faster than that and all we see is a blur with not much detail. Forexample, a bullet being fired, a piece of glassware breaking when it hits thefloor or a hummingbird flapping its wings.
What truly happens is, as these things occur at an energetic pace our eyes can’t stay aware of it. You can consider it the revive rate like that of your PC’s screen. Our eyes and cerebrum together revive what it is taking a gander at each 1/30th of a second (approx). This straightforwardly implies everything that occurs inside that greatly concise period is lost and can’t be seen by human eyes.
Motion pictures and Animations
In any case, don’t be so dampened reasoning that you miss all the ‘activity’. Tirelessness of Vision is likewise the reason which makes all our most loved motion pictures and activitys conceivable. A while ago when the primary livelinesss were made, it was all hand drawn and hued. What you truly observed on screen was every one of these illustrations in a specific succession… .rapidly!
With the approach of the DSLR and Mirrorless Cameras, we have truly introduced an absolutely new and current zone.
In the greater part of the cases, a couple of illustrations for every second. On the off chance that this happened speedy enough; our cerebrum would mystically go along with one picture with the other and make it resemble a smooth and drowsy video. This is actually how we see our regular daily existence.
Presently you know what number of representations it took to make your three minutes of Tom and Jerry kid’s shows.
Excessively High-Speed Cameras have progressed significantly however it truly isn’t simply squeezing record and do bizarre stuff. There is a ton that goes behind the camera to make the recording look sharp thus sensational.
Difficulties Of Using A Super High-Speed Camera
Despite the fact that shooting with a Super High-Speed lunatic of a Camera sounds fun and audacious, it isn’t in every case simple. The main test that Gavin talked about was the everlasting battle with light. A Super High-Speed Camera shoots at galactic speeds and casing rates. That is the thing that they are worked for. Nonetheless, this additionally implies each edge gets next to no time for introduction.
It is about difficult to shoot on a shady dim day; a sunlit day is an unquestionable requirement. In addition, for specific recordings which are shot inside, it needs a silly measure of lighting to help such high casing rates. A wide opening of the focal point may help however not all the time since it likewise important to keep the subject in core interest. Henceforth you will see that the majority of the recordings shot on a Super High-Speed Camera are shot parallel to the camera’s sensor plane. This enables the camera individual to shoot wide and furthermore keep everything in core interest.
Coincidentally, did you realize that the screen speed in these High-Speed Cameras is spoken to by a point instead of a day and age. This is a wording that has been taken from the before days when the camcorders had a moving screen not at all like the electronic shades of the Phantom cameras that Gavin utilizes today.
