So, what is the difference between high end video and cinema grade footage?
I can tell when I am looking at one or the other, but have had a hard time working it out.
The main difference is the realistic look film or film-like cinema footage has, but how is that achieved?
This is what I see (or often don’t).
A three dimensional fullness, enough depth of field to look like the eye sees, a perception of lots of sharpness even if it is disguised by other factors and no flatness in tones or subject rendering.
Really shallow depth has its place, but it needs to be natural fall-off, not forced. Few pro cinematographers use unnatural shallow depth, because it looks like a lens trick. F4 in full frame (f2.8 in Super35 or f2 in M43) is far more commonly used than f1.4 and if 1.4 is used, it is often in context with distance, so the effect is less obvious.
This scene from Barry Linden was shot with a super fast lens to emulate genuine low light interiors from the period, but greater working distance has rendered the subjects naturally to the eye. If really shallow depth and field flatness are used, they need to true to the eye. In this shot we feel like we are looking at it from across a room.
This shot from The Bear is beautiful, but it pushes reality. The perspective, compression and depth of field are an obvious technical manipulation that we accept in context, but are aware of because this is something our eyes cannot do. Unlike the shot above, we struggle to put ourselves in this space naturally.
This depth is dreamy to match the need of the shot, but it is not how we see naturally with too much compression and far too shallow depth of field at the viewing distance.
This is even less natural, showing strong lens compression and magnification and less than natural to the eye Bokeh.
It needs to be sharp like reality, but not bitingly sharp like video perfection. It has invisible roll-off and no tell tale sharp/soft point, which is part of the previous point, the look of clarity over visible sharpness.
I guess another way to say all that is sharpness needs to be invisible, or the effect of it at least. It needs to look like reality, not hyper-reality.
This image is sharp and has shallow depth of field, but the right amount to look natural and the colour, a product of the film tech of the period is also acceptable representing dust, sun and the arrid landscape.
This scene is shot with a wide angle lens and a fast aperture, giving us the feeling of being too close, while also being too shallow in depth rendering. It is hyper sharp, then softened by filtering and the colouring is warm to match the sun shine, but unnaturally so (teal sky?). It looks cinematic, but only because we have been conditioned to accept it as that.
A lot of current shooters using top end digital cine cameras and lenses use filtering to remove the hard-sharp digital look, but this is less appealing than film and has become a look unto itself. The reality is the age of technology reaching a point of perfection that surpasses reality is here.
Ok, funny thing happening here.
I started writing this to try to articulate what made a “film” level image, but seem now to be comparing the old and the new styles of doing that.
The irony is, all of the quality available to film makers these days is often squandered, meaning they could have used almost anything to make it. Super sharp becomes deliberately dreamy, huge exposure range becomes murky, infinite depth of field becomes a slice of un-reality and perfect lenses are flared.
The experience of the movie or TV show has become the experience in itself, more than the attempt to tell a story that has to stand on its own merits.
A rare case from 1917 of something looking “right” using the best gear available, by limiting the shoot to eye-normal lenses and deep depth of field. This is how we see, choosing what top look at in a scene, not having the majority of it taken away from us with tech.
It is up to the director and DP to draw our eye to the important elements using light, blocking, acting and writing, rather than relying on tricky focus and shallow depth of field to do it.
Paul Thomas Anderson, Roger Deakins, Kurasawa, Hitchcock, the Cohen brothers, Wes Anderson, Tarantino and Spielberg all know this, so we should remember it also.
The process is taking over the story.
The irony of course is, artificially created scenes often adhere to realistic needs to help fool us, while real scenes are manipulated to look unrealistic.
