VINTAGE LENSES

HERE ARE SOME MOTION STILLS TESTS I'VE TAKEN FROM RUSSIAN VINTAGE FF35 OPTICAL LENSES PRODUCED IN THE 1970'S WITH SINGLE COATINGS.

I'VE BEEN WORKING WITH A LENS TECH IN THE UKRAINE TO BUILD A FULL FRAME 35MM PL MOUNT CINE SET OVER THE PAST 3 MONTHS. TESTING OF THE VARIOUS CHARACTERISTICS & MECHANICAL OPTIONS I CURRENTLY HAVE MATCHED TWO FOCAL LENGTHS THOUGH IT'S AN EVOLVING PROJECT AND COMMUNICATIONS WITH SOMEONE IN THE UKRAINE IS NOT ALWAYS AS FAST AS I'D LIKE.

FOR THE RIGHT PROJECTS, PAIRING THESE OLDER LENSES WITH DIGITAL SENSORS I CAN ACHIEVE A SUBTLE ORGANIC LOOK CLOSER TO FILM

I'LL HAVE MORE DETAILS AND A COMPLETE SET OF FOCAL LENGTHS IN THE NEXT FEW MONTHS.

IPHONE FLASHLIGHT, STARING POINT SOURCE WITH RAINBOW PARTICLE ABERRATIONS AND MULTIPLE RING FLARES

F2 APERTURE, SHARP FOCAL PLANE VS ORGANIC FALL OFF AND MUTED COLOURS.

SWIRLING OUT OF FOCUS BOKEH & RAINBOW FLARE HIGHLIGHTS FROM A BACKYARD FLOODLIGHT SOURCE.

NATURAL SUNLIGHT BOUNCING OFF A REFLECTIVE METALLIC SOURCE, RAINBOW RINGING, MAGENTA VEILING AND CHROMA SPIGOTS

F2 PORTRAIT, SHARP WITH OUT OF FOCUS AREA RINGING

F2, FOCUS IS SMOOTH & FORGIVING WITHOUT APPEARING SOFT ALONG WITH CIRCULAR BOKEH HIGHLIGHTS.

CANON 5D 35MM, FULL FRAME SENSOR, I SHOT THIS ON THE FLY WALKING IN LOW LIGHT, FOCUS IN NOT ACCURATE, THE HALO FLARE RING & POINT RAINBOW IS OF INTEREST AND SHOWS UP ON WIDE FRAMES AND CHANGES ORGANICALLY TO VEILING AND PARTICLE FLARES IF THE SHOT IS STEPPED IN.

F2, PRACTICAL STREET LIGHTING ONLY, CLEAR WITHOUT BEING OVERLY SHARP

PRACTICAL STREET LIGHTS PLAYING WITH THE SINGLE COATINGS TO PRODUCE ORGANIC VEILING.

AGAIN SHOT ON THE FLY, NOTICE THE MULTIPLE FLARE RINGS AND THE PARTICLE FLARING ON THE FAR RIGHT.

THE PARTICLES SHOW WITHIN THE FLARING, IN MOTION THE EFFECT IS QUIET INTERESTING AS IT MUTATES WITH MOVEMENT.

F2, WIDE AND SHARP ON THE MIDDLE FUEL BOWSER, TAKEN A GOOD 1/2 HOUR PRIOR TO SUNRISE.

MOTION CAPTURE AT 4K AND BEYOND

HIGH RESOLUTION CAPTURE IS BENEFICIAL EVEN WHEN THE OUTPUT RESOLUTION IS REDUCED. ADVANTAGES INCLUDE BETTER IMAGE QUALITY, BUT ALSO EXTEND TO LESS FAMILIAR AREAS INCLUDING CREATIVE FLEXIBILITY, POST-PRODUCTION, PRINTS AND FUTURE-PROOFING. THIS ARTICLE SUMMARIZES HOW EACH OF THESE ASPECTS IS INFLUENCED.

Camera resolutions

OVERVIEW

BETTER RESOLUTION HAS BEEN A PRIMARY GOAL OF TECHNOLOGICAL ADVANCES IN CONSUMER VIDEO AND CINEMA OVER THE PAST SEVERAL DECADES – FROM VHS TO DVD TO BLU-RAY. WITH THE RECENT PUSH TOWARD EVEN HIGHER RESOLUTION DISPLAYS, SUCH AS APPLE’S RETINA DEVICES, THIS TREND IS EXPECTED TO CONTINUE. IN THOSE SITUATIONS, HIGHER RESOLUTION IS CLEARLY BENEFICIAL FOR DETAIL AND REALISM.

ON THE OTHER HAND, RESOLUTION ALSO HAS OTHER LESSER KNOWN BENEFITS – MANY OF WHICH APPLY EVEN WHEN THE OUTPUT RESOLUTION IS REDUCED. A COMMON WORKFLOW WITH TELEVISION HAS BEEN TO CAPTURE AT 4K OR HIGHER, BUT TO DOWNSIZE THIS FOR 1080P DISPLAY. ONE’S INITIAL REACTION MIGHT BE TO THINK THAT ALL THE ORIGINAL RESOLUTION HAS BEEN WASTED, AND THAT ONE COULD ACHIEVE AN EQUIVALENT RESULT BY JUST CAPTURING AT 1080P IN THE FIRST PLACE. HOWEVER, AS THE APPLICATIONS BELOW WILL DEMONSTRATE, THAT INITIAL REACTION WOULD BE A MISTAKE.

IMAGE QUALITY

FIRST AND FOREMOST, DOWNSIZED OR “SUPERSAMPLED” IMAGES SIMPLY LOOK BETTER. THEY TYPICALLY APPEAR CLEANER AND WITH FEWER ARTIFACTS, AND HAVE A MORE THREE-DIMENSIONAL QUALITY DUE TO BETTER MICRO-CONTRAST AND MTF. A 2X DOWNSIZE OFTEN REDUCES IMAGE NOISE SIMILAR TO A 1-STOP REDUCTION IN ISO SPEED WITH TRADITIONAL FILM, FOR EXAMPLE. OTHER DEFECTS, SUCH AS LENS IMPERFECTIONS AND IMAGE PROCESSING ARTIFACTS, ARE ALSO MADE LESS APPARENT. THE NET RESULT IS THAT VIDEO CODECS HAVE A BETTER INPUT IMAGE, WHICH IMPROVES BANDWIDTH EFFICIENCY AND QUALITY – EVEN WHEN SHARING AT A SMALL SIZE ONLINE.

NOTE: ABOVE COMPARISON WAS MADE USING A HIGH ISO SETTING ON A NOISY DIGITAL VIDEO CAMERA. NOISE WILL BE MUCH LOWER WITH RED®, ALTHOUGH THE QUALITY IMPROVEMENT FROM DOWNSIZING WILL BE JUST AS PRONOUNCED.

CREATIVE FLEXIBILITY

A HIGHER RESOLUTION MASTER EXPANDS THE POST-PRODUCTION POSSIBILITIES. FOR EXAMPLE, ONE CAN CROP TO CREATE AN ALTOGETHER DIFFERENT COMPOSITION, OR A TIGHTER TELEPHOTO FRAMING. ALTERNATIVELY, ONE CAN INTENTIONALLY PAD THE FRAME AROUND A MOVING SUBJECT TO DECREASE THE CHANCE THEY’LL ACCIDENTALLY FALL OUT OF FRAME. THE END RESULT IS THAT RE-SHOOTS ARE LESS LIKELY – REDUCING COSTS AND PRODUCTION TIME.

PRINT-READY STILLS

STILL FRAMES FROM 4K+ VIDEO ARE WELL-SUITED FOR PROFESSIONAL QUALITY PRINTS AT A WIDE VARIETY OF SIZES. THIS IS PARTICULARLY HELPFUL WHEN A FASHION VIDEO WILL ALSO BE USED AS A STILLS PHOTO SHOOT, OR WHEN MOVIE FRAMES NEED TO BE PULLED FOR FULL-PAGE MAGAZINE ADVERTISING. SUCH CAMERAS EFFECTIVELY MERGE THE ROLES OF PHOTOGRAPHER AND VIDEOGRAPHER.

VFX & STABILIZATION

A HIGHER RESOLUTION MASTER GIVES VFX ARTISTS MORE TO WORK WITH. ZOOMS, PANS AND OTHER CAMERA MOVEMENTS CAN BE SIMULATED IN POST-PRODUCTION WITHOUT HAVING TO PHYSICALLY MOVE THE CAMERA. EVEN PRONOUNCED VIBRATIONS OR OTHER UNINTENTIONAL CAMERA MOVEMENTS CAN BE MINIMIZED WITHOUT SACRIFICING OUTPUT RESOLUTION, FOR EXAMPLE. SIMILARLY, CORRECTIONS FOR LENS DISTORTION AND PERSPECTIVE ARE LESS DETRIMENTAL TO IMAGE SHARPNESS. KEYING AT A HIGHER RESOLUTION IS ALSO MORE ACCURATE, AND CAN BE CRITICAL WITH HAIR OR OTHER HIGHLY DETAILED GREEN SCREEN FOREGROUNDS.

FUTURE PROOFING

HIGH RESOLUTION CAPTURE ENABLES FUTURE RE-RELEASES ON NEWER FORMATS – IMPROVING THE MONETIZATION POTENTIAL OF EXISTING FOOTAGE. WE’VE ALREADY SEEN THIS HAPPEN WITH STANDARD DEFINITION CONTENT RENDERED UNUSABLE WITH THE MOVE TO HIGH DEFINITION – THOSE THAT DIDN'T KEEP UP WERE OUT OF LUCK WHEREAS THOSE CAPTURING HD WERE ABLE TO REPURPOSE THE CONTENT CREATING A SUBSTANTIAL STREAM OF ADDITIONAL REVENUE. WITH A FUTURE THAT WILL INCLUDE INTERNET DELIVERY TO 4K ULTRA HIGH RESOLUTION DISPLAYS AND PROJECTORS (UHD), HAVING HIGHER RESOLUTION FILES WILL BECOME MORE IMPORTANT THAN EVER.
