INTRODUCTION
In 1997,Panavision and Sony announced their
collaboration on the developmentofa24P digitalhigh
definition camerasuitable foruse by filmmakers to
create big screen motion picture image quality. We
knew,from 45 years ofexperience,thata complete
imaging system approach was the only way for
traditionalfilm crewstomakeaseamlesstransitioninto
digitalproduction.Withthisinmind,wemadeanumber
ofmodificationstotheSonyHDW-F90024Pcamera.For
starters,the Panavised camera received aheavy duty
frontplate and lensmountmodified to work with our
speciallydesignedPrimoDigitalTMlenses.Thesystem now
accommodates mostofourstandard film camera
accessories as wellas new accessories designed
exclusivelyfordigitalcinematography.
In addition to the mechanicalmodificationsto the
camera,auniqueopticalpre-filtergivesyoubettercolor

forblue screen effectscinematography. Last,butnot
least,wedesigned the new ULTRAVIEWviewfinderfor
studio and handheld cine-style use. Itpresentsa 2

1.8 PROGRESSIVEVS.INTERLACE
The24PHD ElectronicCinematographyCameraSystem
is a PROGRESSIVE capture deviceunlike oldervideo
cameras thatcapture the image in an INTERLACE
manner.
INTERLACE: A videoscanningsystem wheretheodd
numbered linesare scanned separately
from theevennumberedlines.Theodd
numberedlinesform fieldone,theeven
lines make up the second field. The
combinationoftwofieldscomprisesone
frame.
PROGRESSIVE: A video system in which alllines
comprising aframe are scanned in
sequenceratherthaninterlaced.
HD900F
GENERALSPECIFICATIONS
The interlace mode ofcapture hasinherentmotion
artifactsand is difficultto transferto film. The
progressive mode ofshooting capturesthe complete
resolution atonce,atthe same pointin time;and
thereforeallowsaperfectone-to-onetransfertofilm.

GENERALSPECIFICATIONS
Duetoinherentdifferencesin imagingcharacteristicsbetweena CCD,a
monitor,and the human eye,certain translationsare necessary. The
Gamma andMatrix settingsinterpretthe CCD imageso thatthemonitor

1.9 GENERALIMAGING CONSIDERATIONS
Shooting24PforFilm output:
Since the HD monitoris much closerto thefinalvideo image,butonly an
approximation ofthe film image,there are some recommendationsin orderto
maximizequalityoffinalfilm output:
Wecautionagainstusingpaintmenusforimagemanipulation iffinishing on film
because the monitorimage and painteffectsdo notdirectlycorrelatetothe film
image,andtheyareusuallyirreversible.
When shooting forvideo finish,the HD monitoris in effectyourfinalimage.
Therefore adjustmentscan be madein thecamera withmoreconfidence in the
intendedresults.Standardrecommendedsettingsare:
-GAMMAON asabove
-MATRIXON,PRESETON,ITU-709
-USERMATRIXOFF
-MULTI-MATRIXOFF
- GAINsetto6dBorless.
Allthepaintadjustmentscanbesetforcreativeeffect,buttheusermustbeaware
thatmany settingscannotbe undonein post. Ontheotherhand,ifthecamera
