PostHeaderIcon The Demand for Uncoated Optics

Normally when light strikes a glass surface a portion of the beam is reflected. This loss of light is compounded in lenses with many elements, which can lead to a serious reduction in light transmission and speed. More and better lens coatings can reduce the light loss dramatically enabling lenses to maintain high speed with good resolution.

Now it may be a figment of my imagination but lately it seems more and more DPs are employing uncoated lenses. At a time when 4K and higher resolution cameras are all the rage and most shooters are indeed insisting on them it strikes me as deeply ironic and even macabre that many shooters are choosing to capture images with vastly increased flare and much much less resolution.

Of course, resolution, like wardrobe, music, and everything else, is and always has been another function of the visual story. For decades shooters used diffusion filters, metal gratings, and silk stockings, to effect a scene, to add fog or atmosphere, and yes, reduce resolution.

The great director Sidney Lumet once said that story is the conduit through which all decisions flow. The lowering of resolution is simply another storytelling device to be used and abused by shooter-storytellers of every stripe. The use of uncoated optics (as in the case of my current project shooting in Japan) is simply a reflection of this craft-oriented thinking.

Higher and higher resolution.  It’s what we all want, right?  And the camera makers responded.  NAB and Broadcast Asia 2014 were awash with 4K, and IBC will soon experience the same fate. Larger sensors and ever higher pixel counts are the rage so bring it on baby.  More resolution is better, right?

Well, maybe not. The same super high resolution that lends the professional look and feel to our images has an unexpected downside. We shooters as masters of our craft have learned to compose with skill and taste, by excluding everything that detracts from the visual story.

The advent of 4K, 5K, and higher resolution has introduced an era of boundless post-camera hanky-panky, including most disturbingly the willy-nilly indelicate cropping of our well-considered images. In this new brave digital world shooters have grown accustomed of course to seeing our work tweaked ad infinitum downstream. Many scenes, say, shot on green screen, must be composited, or an image must be stabilized, or a guide wire removed. We shooters accept this reality of working in a modern all-digital world.

Problem is, owing to the arrival of 4K and heaven forbid 8K later this decade our images are being transformed and systematically trashed in a way we’ve never experienced. The shenanigans we are seeing, the re-framing and re-cropping of our work by less talented others, will only become more common as the pixel count rises. Alas giving producers, editors, and indecisive directors, so much resolution invites foul play. And that is exactly what we are increasingly experiencing.

So sure we love 4K, and more and more we are willing to put up with its challenges: the massive data loads, the high compression in-camera, the bevy of high-frequency artifacts and chromatic aberrations appearing suddenly in our re-purposed SLR lenses. Of course we love 4K. Fine. Let’s also consider the unintended consequences and the impact on our craft.

Higher and higher resolution. Is it what we really want? Think about it.

4K is growing up around us. How much resolution is enough for your stories? How much is desirable?

PostHeaderIcon A Flicker of Truth

Whether you’re shooting time-lapse, fast or slow motion, or even more routine scenes under temperamental fluorescent lighting, chances are you’ve confronted flicker and have thrown up your French flag in frustration. Today the flicker menace seems even greater owing to most cameras’ tiny viewfinders that make it difficult to spot on location, increased use of LEDs and other discharge lighting, and greater availability of cameras capable of shooting at off frame rates.

Flicker may be seen as a faint background pulsating effect, or more dramatically as a significant fluctuation in exposure from frame to frame. In most cases the flicker may be reduced or eliminated through use of the ClearScan or Synchroscan shutter found in newer video and hybrid cameras like the Panasonic GH4. Fine shutter tweaking should always be your first course of action. Shooting 24p in 50Hz countries? Set the camera shutter (in degrees) to 172.8º. Shooting 30p in 50Hz countries? Set the camera shutter to 108º, 216º, or 324º. The use of a camera’s fine shutter is imperative if one is to avoid flicker stemming from the field frequency mismatch when shooting abroad.

Nevertheless regardless of our best efforts the specter of objectionable flicker will occasionally raise its ugly head, and this is where Digital Anarchy’s Flicker Free plug-in can save your backside. Compatible with Final Cut Pro 7 & X, Avid, Adobe Premiere, and Adobe After Effects, the plug-in can be especially effective for eliminating flicker in time-lapse and slow-motion footage, and in certain scenes illuminated by HMIs, fluorescents, and LEDs.

The Flicker Free software is simple to use with presets for time lapse, slow motion, computer/TV screen, and archival film restoration. This level of simplicity is possible because the flicker cadence in most cases is a regular pattern. In case of need further tweaking of the underlying parameters is still possible from within the plug-in.

Flicker Free’s THRESHHOLD setting specifies how much change in brightness is tolerated from frame to frame. While significant changes in brightness from frame to frame are usually deliberate, this is not the case when shooting neon or in an out of sync 50Hz/60Hz environment.  In such scenes exhibiting a brightness fluctuation in excess of 20 percent from frame to frame Flicker Free is not likely to offer much help.

Digital Anarchy’s Flicker Free plug-in is supported in most major editing platforms. It will work either very well. Or not at all.


PostHeaderIcon Nothing Digital About This

Some of you may be aware that I have a vague and passing interest in vintage English bicycles manufactured from 1935 to 1950. Respected makers like Raleigh, Rudge, Humber, and Sunbeam, ruled the roost during this era of petrol rationing prior to and for several years  after World War II.  These bicycles were not generally well chromed or even particularly well finished. They were not works of art to be admired on a wall in a museum but were in fact heavy utilitarian beasts to be used daily in all kinds of weather for the purpose of simple transportation. This morning in London many of these humble machines from decades ago once more saw the light of day for the annual London Tweed Run.   I can report that I was present and orgasmic for the entire 3.75 hours of this blessed event.

PostHeaderIcon Panasonic’s new GH4: Digital Cinema Camera By Any Other Name

Any way you hang it or support it the new Panasonic GH4 is an amazing camera, with true Cinema 4K (4096 x 2160) resolution, VFR 2-96 FPS, 10-bit 4:2:2 200 Mbps All-I frame FHD, plus optional 3G-SDI output and balanced XLR audio inputs.  Given the hybrid camera’s latest Micro Four Thirds imager, low noise in light, and 11 stops of latitude, the produced images look a lot like what one might see in a digital cinema. The camera doesn’t feel or operate like a true digital cinema camera however.  And therein lies the rub.

Cameras cannot be judged by raw performance or specifications alone.  We still have to be able to handle the camera efficiently under a wide range of conditions and keep it in focus. Operational considerations matter!

Here is a link to my current review of the camera in Studio Daily Magazine:

PostHeaderIcon Aspiring Shooters in the Philippines

I continue to be amazed and humbled by the young shooters I encounter around the world, and this is especially the case in Asia where I have been conducting camera and lighting workshops, including last week in Manila and Makati City.  I was especially impressed by the enthusiasm of the young shooters at television station GMA7 under the tutelage of Virgilio Muzones, a true mentor and friend to hundreds of young aspiring craftsmen.  My followup public workshop in Makati attracted 300 aspiring filmmakers, from first-year university students to newly minted pros eager to enhance their visual storytelling prowess. I can’t wait to see what the young people do next with their newfound skills! For sure great things are in store for the young shooters of the Philippines!

PostHeaderIcon The Truth About Crop Factors

A reader wrote me recently regarding an online merchant’s ad touting the benefits of a 50mm DSLR lens on a smaller format camera. The ad claimed that due to the 2X crop factor in a Micro Four-Thirds camera like the Panasonic GH3 the 50mm lens could serve as the functional equivalent of a moderate telephoto, a popular choice for portrait photographers.  At first the reader accepted the ‘equivalency’ assertion, but now he is no longer sure. Since the narrow angle of view is due to the smaller imaging target rather than magnification, can a 50mm lens ever be functionally or aesthetically equivalent  to an 85mm or 105mm?

A 50mm lens is still a 50mm lens regardless of the camera’s target or sensor size.  While it’s true that the 2x crop factor reduces the viewing angle and field of view the foreshortening of perspective one expects from a moderate telephoto is not present. This contributes to an unnatural cropped look; this look characterized by the increased depth of field of the 50mm focal length compared to an 85mm or 105mm.

The same logic should occur to camera folks touting the virtues of 4K image capture which they say makes possible significant cropping to HD 1920 x 1080 inside the 4096 pixel frame. The cropping may indeed constrain the field of view  but the unnatural perspective inside the cropped frame may appear be potentially disturbing to audiences.

SLR portrait lenses 85mm – 105mm are effective because they help preserve a normal i.e. realistic roundness in the face of subjects when shooting at normal distances of six to eight feet (1.5m – 2.5m).  A 50mm lens at only a few feet from the subject may produce too much roundness and thus produce a look like an ogre. Maybe this is what you want. Maybe it isn’t.

Given a 2X crop factor this 50mm can never be the functional equivalent of a moderate telephoto portrait lens.

PostHeaderIcon Hunger in Asia

My November workshops in Malaysia and the Philippines have again confirmed at least in my mind the intense hunger for education and training in that part of the world. Notwithstanding my few days in the typhoon-devastated areas outside Cebu where the hunger of people is more much literal, my workshops in Kuala Lumpur and Manila were oversubscribed by hundreds of eager participants in each city. In Malaysia those attending were mostly news cameramen looking to expand their visual storytelling skills and career opportunities at their respective stations.

In Manila the Fast Forward event at the city’s immense convention center attracted nearly 350 attendees comprised mostly of independent filmmakers and producers. More workshops in Asia are in the works for early next year! Stay tuned!
