On Digital Film Grain and Medium Specificity

I belie­ve that – regard­less of the viewer’s breadth of know­ledge – one has an inher­ent sen­se of what is right or wrong in an image. It comes down to a ques­ti­on of ethics. How a reco­g­nisable object – a person’s skin, a tree, moon­lit ski­es, light fix­tures – can be ren­de­red obs­ce­ne when the cur­rent film­ma­king appa­ra­tu­s­es cede con­trol over to the tech­ni­ci­an ins­tead of the object. All the tech­ni­cal know-how and obses­si­ve­ness that can come with the came­ra (whe­ther it’s a vin­ta­ge fetis­hi­sa­ti­on of ana­log or the fas­tidious­ness of kee­ping up with the latest ARRI ALEXA and Black­ma­gic models) under­mi­nes the neces­si­ty and resourceful­ness man­da­ted by a limi­t­ed tool­set, a limi­t­ed tool­set more clo­se­ly resembling the stigmatisms/​astigmatisms inher­ent to visi­on. It used to be an obses­si­ve­ness only affec­ting film­ma­kers with access to the­se tools. But the “pro­sumer” tech­no­cra­cy now inher­ent to rea­di­ly acces­si­ble, high-reso­lu­ti­on came­ras make anyo­ne pri­vy to a once desi­ra­ble and inac­ces­si­ble stan­dard, a stan­dard con­tin­gent on mani­pu­la­ti­on (once ana­log, now digital).

Fix­a­ting on a favou­ri­te cine­ma­to­grapher also seems the wrong way to approach a film, ano­ther ten­den­cy in this cine­phi­lia-as-tech­no­cra­cy (or vice-ver­sa). A cinematographer’s artis­tic con­tri­bu­ti­ons – like many a direc­tor – can best be approa­ched on a case-by-case basis. In many ide­al ins­tances, a cine­ma­to­grapher and direc­tor push each other out­side of man­da­tes they’ve pre­vious­ly set for them­sel­ves, even if it’s only for one or two films. Though ide­al, many estab­lished film­ma­kers – of the ilk I men­ti­on below – remain igno­rant of any­thing bey­ond boun­da­ries they’ve set for them­sel­ves, resul­ting in may­be one pro­duc­ti­ve shake-up in their fil­mo­gra­phy at the hands of a can­ny col­la­bo­ra­tor. Vie­w­ing a cinematographer’s care­er stan­da­lo­ne, howe­ver, can limit their role to that of a visu­al sty­list. The­re is very litt­le wri­ting about cine­ma­to­graph­ers that expands this cate­go­ri­sa­ti­on. Even though it’s not the covera­ge in its­elf that’s the pro­blem, it’s what it is pre­mi­sed on, being: the tech­no­cra­cy and fetis­hiza­ti­on of what is both in and out­side of the image.

Of the films below, I wat­ched The Twen­tieth Cen­tu­ry and Uncut Gems at the Lido Cine­ma and First Cow at Cine­ma Nova, both in Mel­bourne. As with most films not finis­hed in a 16:9 aspect ratio, each of the abo­ve was shown in open mat­ting, the black bars on eit­her side of their aspect rati­os as obvious as the images them­sel­ves. This is now the norm in Mel­bourne, as per­haps only a cou­ple of cine­mas accom­mo­da­te the cor­rect aspect rati­os. The pro­jec­tor over­com­pen­sa­tes in this regard, the only “fault” of a digi­tal pro­jec­tor that chan­ges how a film is seen.

Wat­ching The Twen­tieth Cen­tu­ry, direc­ted by Matthew Ran­kin, I was instant­ly sus­pi­cious of the 16mm imagery on dis­play, far too “fil­mic” despi­te being shot on film. Loo­king at an on-set pho­to­graph con­firm­ed that it was shot on 16mm, but I got no satis­fac­tion from this know­ledge. I still couldn’t deci­de – while wat­ching the film – whe­ther it was shot digi­tal­ly or on film. And that still seems like the only valid respon­se to what I saw, regard­less of what was actual­ly used during pro­duc­tion. I felt much the same wat­ching it as I do when wat­ching a con­tem­po­ra­ry music video or com­mer­cial shot on 16mm. At an ear­lier point in time, 16mm images trans­fer­red to DCP’s or digi­tal files felt easier to iden­ti­fy, but now the digi­tal­ly scan­ned 16mm image is ubi­qui­tous to the point of ille­gi­bi­li­ty – eit­her as a ful­ly 16mm or 4K scan of an image. It’s an inter­me­dia­ry likely untouch­ed by human hands, undo­ing the disin­ge­nuous dri­ve to shoot on ana­log for­mats, often moti­va­ted by a desi­re for “authen­tic” or “hand-made” qua­li­ties. They may have paid and gone through the effort of shoo­ting on 16mm, but this choice is both too evi­dent as a flou­rish and too distant from its ori­gi­nal for­mat to regis­ter as any­thing other than a sty­li­stic show­ca­se; a choice self-impo­sed, not necessitated.

I was sear­ching throug­hout The Twen­tieth Cen­tu­ry for two objects/​landscapes that main­tain – when shot through a digi­tal sen­sor – cha­rac­te­ristics distinct from cel­lu­loid (even when trea­ted with arti­fi­ci­al grain and exten­si­ve golour gra­ding in post-production):

  1. Prac­ti­cal red light sources: The­se remain dif­fi­cult to cap­tu­re with digi­tal sen­sors, giving off a pink/​paler sha­de than how the actu­al light source appears to the human eye. Tail­lights are an exam­p­le of this dis­crepan­cy in an easi­ly reco­g­nisable arti­fi­ci­al light source. They often appear in digi­tal pho­to­gra­phy as a pink-ish glow, show­ing the com­pon­ents of the light’s red­ness, but not the colour itself.
  2. Night­ti­me exte­ri­ors: Digi­tal sen­sors have dif­fi­cul­ty cap­tu­ring deep black hues, espe­ci­al­ly tho­se of the night sky, unless it’s been trea­ted in the colour gra­de. Night ski­es appear as sla­te gray or dark vio­let with the clouds often fair­ly legi­ble. The bene­fit of this cla­ri­ty at night­ti­me is one’s abili­ty to digi­tal­ly cap­tu­re the illu­mi­na­ted clouds sur­roun­ding the moon, not mere­ly the moon its­elf – as it tends to appear on cel­lu­loid. This is becau­se a digi­tal sen­sor is more sen­si­ti­ve to natu­ral and arti­fi­ci­al light, depen­dent on a video LOG[1] codex ins­tead of a film nega­ti­ve with a limi­t­ed ASA. The digi­tal came­ra also has an ASA/​ISO limit, but the ALEXA Mini (the came­ra used in some capa­ci­ty on most films men­tio­ned below) has a natu­ral ISO of 800, grea­ter than any exis­ting film stock, which are manu­fac­tu­red nowa­days at ASA’s of 500T (T=Tungsten, desi­gned for 500 ASA sen­si­ti­vi­ty under arti­fi­ci­al light) or 250D (D=Daylight, or 250 ASA sen­si­ti­vi­ty in natu­ral light).

On the sub­ject of self-impo­sed limi­ta­ti­ons, the pro­cess of shoo­ting on film is now one step clo­ser to a digi­tal camera’s work­flow as prin­ting pro­ces­ses, film stocks and labo­ra­to­ries scar­ce­ly exist for exten­si­ve opti­cal colour timing. The still-enig­ma­tic pro­ces­ses and errors that deve­lop an ana­log image are the camera’s afo­re­men­tio­ned (a)stigmatisms. The­se (a)stigmatisms are fur­ther lin­ked to the opti­cal eye­pie­ce that the film­ma­ker looks through, as all that sepa­ra­tes what one and the came­ra see are a few glass optics. Insi­de the digi­tal eye­pie­ce is a screen, one simi­lar to the camera’s moni­tor dis­play­ing its RAW codex of what the came­ra con­fi­gu­res, adjus­ted with eit­her a cus­to­mi­zed or rea­dy-made Look Up Table[2]. The digi­tal sensor’s cap­tu­re of red light sources, for exam­p­le, is an appro­xi­ma­ti­on of what was pre­vious­ly – bet­ween the opti­cal eye­pie­ce and came­ra nega­ti­ve – a media­ti­on of reco­g­nisable forms. The­re are no inher­ent (a)stigmatisms to the pro­cess of a 2–4K reso­lu­ti­on digi­tal work­flow. Now that 16 and 35mm images are – with few excep­ti­ons –finis­hed within the­se reso­lu­ti­ons, the­se ana­log (a)stigmatisms have also been lar­ge­ly smoot­hed out (though film’s finer-attu­n­ed expo­sure levels still allow for the afo­re­men­tio­ned, reco­nis­ab­ly human expo­sure levels and colour tem­pe­ra­tures). Each qua­li­ty in the image is limi­t­ed to the inten­ti­ons of their tech­ni­ci­ans, a mega­lo­ma­nia that now dic­ta­tes how con­tem­po­ra­ry cine­ma and – fur­ther­mo­re – the eyes that watch it pro­cess the­se reco­g­nisable forms.

The­re need to be new, digi­tal limi­ta­ti­ons. Once-com­mon Stan­dard Defi­ni­ti­on came­ras, cons­trai­ned to a 720×576 reso­lu­ti­on, limit what can be adjus­ted within a set ran­ge accor­ding to a lower ISO and hig­her con­trasts. But with 2–4K came­ras, the now out­mo­ded tech­ni­ques of yore (the old len­ses and tungs­ten lights) don’t pro­per­ly decon­s­truct the cla­ri­ty and con­trol inher­ent to their high reso­lu­ti­ons. Ana­mo­r­phic len­ses moun­ted onto a digi­tal sen­sor eli­mi­na­te the time cons­traints inher­ent to a 4‑perforation film maga­zi­ne (3−4 minu­tes on a por­ta­ble, 400ft mag). But this dis­crepan­cy in time – and con­se­quence – chan­ges the image. With the­se advan­ces made and cos­ts cut, a digi­tal­ly cap­tu­red ana­mo­r­phic image, as a result, looks cheap. This comes back to the intui­ti­on I spo­ke of abo­ve. Regard­less of the tech­ni­cal know-how or the pre­fe­rence for film or digi­tal, my con­vic­tion remains when an image is “wrong”. Digi­tal-sen­sor ana­mo­r­phic images are wrong, as is foo­ta­ge trea­ted with arti­fi­ci­al film grain in the colour gra­de, as is cel­lu­loid scan­ned and over­ly mani­pu­la­ted digi­tal­ly from the deve­lo­ped negative.

An egre­gious exam­p­le of the three ten­den­ci­es abo­ve is in Uncut Gems. Wat­ching it in the cine­ma, I deter­mi­ned the digi­tal seg­ments from tho­se shot on 35mm, but felt – as with The Twen­tieth Cen­tu­ry – that I’d dis­co­ver­ed not­hing more of the images them­sel­ves. This is the pre­vai­ling dis­ap­point­ment of tech­ni­cal inves­ti­ga­ti­ons and the dubio­us images that encou­ra­ge them. The­re have been too many artic­les spea­king of the tech­ni­que invol­ved in the­se dubio­us images: The Saf­dies pro­fes­sing their love for cine­ma­to­grapher Dari­us Khond­ji, inter­views spea­king of ana­mo­r­phic len­ses, the time cons­traints of 4‑perf film stock, focus pul­ling and sin­gle-came­ra setups.

The­re was a shift from see­ing the film on a TV and then at a cine­ma, obvious­ly, but not in the way I expec­ted. As with The Twen­tieth Cen­tu­ry, open mat­ted black bars were evi­dent, this time at the top and bot­tom of a 2.39 aspect ratio. What was more evi­dent in the theat­re was a dis­crepan­cy bet­ween foo­ta­ge shot digi­tal­ly and foo­ta­ge shot on film. In the afo­re­men­tio­ned covera­ge of the film, cel­lu­loid was pushed to the fore­front as its aes­the­tic sel­ling point, spe­ci­fi­cal­ly long lens ana­mo­r­phic. On Kodak’s blog and in inter­views, it was sta­ted that only night exte­ri­ors were shot digi­tal­ly. In the theat­re it beca­me evi­dent that the fol­lo­wing sce­nes were also shot digitally:

  • The ope­ning minu­tes set in Ethio­pia (but shot in South Africa)
  • The night­ti­me exte­ri­ors and inte­ri­ors, which make up rough­ly 50 minu­tes of the film’s runtime
  • The sce­nes towards the end of the film fea­turing Julia Fox, in both the heli­c­op­ter and at the Mohe­gan Sun casino

But again, I felt neither gra­ti­fi­ca­ti­on nor dis­ap­point­ment in iden­ti­fy­ing the­se sce­nes as such. Making up near­ly half the film, the key iden­ti­fy­ing fea­ture of the abo­ve sce­nes was the grain pre­do­mi­nant in the image. Rea­ding up on it, 35mm ele­ments were film­ed on a grey card and super­im­po­sed over the digi­tal­ly cap­tu­red images, in addi­ti­on to the high ISO digi­tal noi­se that appears as its own, distinct grain ele­ment in low light con­di­ti­ons. The digi­tal­ly cap­tu­red sce­nes were shot with the same ana­mo­r­phic len­ses as the sce­nes shot on film, an attempt at medi­um con­sis­ten­cy that, ins­tead, stret­ched and bro­ke apart the digi­tal sen­sor, dis­tort­ing it with an ease non-exis­tent when lar­ge-for­mat cel­lu­loid is shot through with the same lenses.

The arti­fi­ci­al grain and stret­ched frame felt emp­ty, despi­te the noi­se and grain buz­zing around the screen, appearing on top of the image ins­tead of within it. The grain didn’t con­form to its cor­re­spon­ding colour or con­trast, first of all. From an inter­view with ASC Maga­zi­ne, Dari­us Khond­ji refer­red to addi­tio­nal grain ele­ments as “grain ghosts”. Taking this into account, one is loo­king at dead digi­tal images – or at least an image equi­va­lent of an allo­graft, sur­gi­cal­ly injec­ted with cada­ver bones to com­pen­sa­te for a life non-exis­tent other­wi­se. The intent of this grain appli­ca­ti­on – as with the ana­mo­r­phic len­ses – is to help it flow with seg­ments actual­ly shot on film. But the overt intent undoes medi­um spe­ci­fi­ci­ty. One would shoot digi­tal­ly in low light sce­na­ri­os to get a grea­ter expo­sure level and abili­ty to adjust high­lights in the sce­nes, but the appli­ca­ti­on of grain – both prac­ti­cal­ly and impli­cit­ly – undoes this by mud­dy­ing the actu­al image that was expo­sed in-came­ra. I’m not inte­res­ted in con­fron­ting Khond­ji on his logic, but there’s sus­pi­ci­on that ari­ses with tech­ni­ci­ans like him who very easi­ly bow to ques­ti­ons about their tech­ni­que – most of them encou­ra­ged by the likes of both ASC and Film­ma­ker magazines.

It was in the scree­ning of Uncut Gems that I also saw a trai­ler for First Cow, a film I’d alre­a­dy seen at home months befo­re. I was instant­ly aver­se to the images, adjus­ting to foo­ta­ge I never remem­be­red wat­ching. As with Uncut Gems, the grain ele­ments were dis­trac­ting, to the ext­ent that the film’s expo­sure was also great­ly affec­ted by the grain, sap­ping out high­lights and natu­ral light pre­do­mi­nant in the images.

See­ing the film again in a theat­re (with the black bars, again), I was reassu­red by a more con­sis­tent image, the one I remem­be­red wat­ching at home and who­se arti­fi­ci­al grain was appli­ed so as to for­get about it minu­tes into the film. Unli­ke Uncut Gems, it was shot enti­re­ly on an ALEXA Mini, crea­ting a more con­sis­tent image than Khondji’s mix of ana­log and digi­tal for­mats. Kel­ly Rei­chardt and cine­ma­to­grapher Chris­to­pher Blau­velt also shot Night Moves on the ori­gi­nal model of ALEXA with simi­lar amounts of low-light sce­na­ri­os and grain application.

Colour gra­ding is usual­ly the final step in the film­ma­king pro­cess, along with sound-mixing, so the trailer’s visu­al dis­crepan­ci­es may have been from an unfi­nis­hed gra­de. Eit­her that or A24 wan­ted to turn up the levels of expo­sure, making it more con­ven­tio­nal­ly legi­ble and going against Rei­chardt and Blauvelt’s intentions.

A more obvious unfi­nis­hed gra­de that struck me was in the trai­ler for Dark Waters. Being the first film Todd Hay­nes and Edward Lach­man shot digi­tal­ly tog­e­ther, the­re was a bland uni­for­mi­ty to the images that I don’t asso­cia­te with eit­her the film­ma­ker or cine­ma­to­grapher. Wat­ching the finis­hed film, there’s a noti­ceable dif­fe­rence in the colour gra­de. The con­trast is much more toned down and the image more tex­tu­red, attri­bu­ta­ble to the grain appli­ed throug­hout. Unli­ke Uncut Gems and First Cow, Lach­man uti­li­sed a pro­gram cal­led Live­Grain, which pro­fes­ses to be a “real-time tex­tu­re map­ping” tool that stra­te­gi­cal­ly appli­es grain to digi­tal foo­ta­ge, adver­ti­sed as an alter­na­ti­ve to shoo­ting on film. Uncut Gems and First Cow appli­ed real grain ele­ments through DaVin­ci Resol­ve, whe­re­as Lach­man used a more recent tool exclu­si­ve­ly licen­sed to lar­ger-sca­le pro­duc­tions. Live­Grain’s web­site shows off a rela­tively short and exclu­si­ve list of pro­duc­tions that have used the soft­ware, many of them eit­her Net­flix or HBO pro­duc­tions. Becau­se of a lack of trans­pa­ren­cy on their web­site, I have no way of iden­ti­fy­ing a pri­ce ran­ge for the soft­ware nor who could have access to it. Based on the pro­duc­tions that have used it and litt­le else available on the web­site, it seems more inac­ces­si­ble than the cel­lu­loid it’s try­ing to emu­la­te – or more likely replace.

Dark Waters (taken from the trailer)

Rea­ding inter­views with Lach­man, he expres­sed resis­tance towards shoo­ting on an ALEXA Mini, sta­ting that he com­pen­sa­ted for the image’s cla­ri­ty by using Tungs­ten lights, gels, old len­ses and the afo­re­men­tio­ned grain soft­ware to “decon­s­truct” the image. I under­stand his frus­tra­ti­ons – likely bey­ond his con­trol – but shoo­ting a digi­tal sen­sor through older equip­ment in no way ame­lio­ra­tes the real (but few) sacri­fices actual­ly inher­ent to high-end digi­tal sen­sors. Ins­tead of the con­trast pro­blems being work­ed to his advan­ta­ge, we see it cover­ed up in the finis­hed film, an effect high­light­ing the absence of celluloid.

First Cow and Dark Waters are the least egre­gious, recent examp­les of films using digi­tal grain that I know of. But it remains that, through the examp­les abo­ve, I’m no lon­ger inte­res­ted in argu­ments of film vs. digi­tal, espe­ci­al­ly if tho­se advo­ca­ting for film – like Lachman/​Haynes and Reichardt/​Blauvelt – are wil­ling to sacri­fice the image they’re cap­tu­ring, so as to sub­li­ma­te it with the ever-aspi­ra­tio­nal “fil­mic” look (a word used to descri­be ever­y­thing but images shot on film). Inver­se­ly, film its­elf is also distanced from its mate­ri­al con­di­ti­on by the digi­tal pha­ses requi­red for their editing and exhi­bi­ti­on. The­se methods only seem to be ways of distancing one from their given tools, tools that cap­tu­re the sur­roun­ding light in the litt­le amount of time that per­mits it, the simp­lest way I can try to arti­cu­la­te the prac­ti­ce of being a filmmaker.

Through the­se now-stan­dard prac­ti­ces, film­ma­king seems far more distant than it actual­ly is. Even the bene­fi­ci­al imme­dia­cy of a digi­tal camera’s images needs to be stret­ched out in pha­ses and finis­hed in a stu­dio, if we were to go by the films abo­ve. The tech­ni­ci­ans feel it neces­sa­ry to elon­ga­te the pro­cess of crea­ting an image eit­her out of habit or by dint of the gro­wing pains still evi­dent in the­se still-nas­cent digi­tal appa­ra­tu­s­es. The ques­ti­on of a “look” and how it can be mani­pu­la­ted bemu­ses in the end as – with all the self-impo­sed and pre-exis­ting hurd­les – I strugg­le to find an image beneath the affects.
