BlurFixAirInstructions
Introduction
CongratulationsonyourpurchaseoftheBlurFixAirwithfilter(CP,ND4,orND8/CP)!Youhavepurchased
aqualityfilterforyourGoProHero3orHero3+camera.TheBlurFixAirisintendedforlightweight
applicationsorapplicationswheretheGoProcameraisusedwithoutthehousingsothatamicrophonecan
belinkedtothecamera(i.e.airplanecockpitduringinstruction,racecardashboard,etc.)TheBlurFixAir
withfilterweighsonly7.6gramsmakingitidealforquadcopteruse.Ifusedwithagimbal,youmustcheck
withyourgimbalmanufacturertoensuretheadditionalweightisallowableandtheBlurFixAirwillnotcause
damagetothegimbalorcauseittoovercorrectandgolimp.Likemanyofourfilteradapters,theBlurFix
AirisCNCmachinedoutofDelrin®whichismoreexpensivethanbilletaluminumbyvolumethisisnotjust
anothercheapinjectionmoldedproduct.DelrinwasselectedsothattheBlurFixAirwillpreciselyslipover
thelensflangeonyourcamera.We'veincludedanoptionaloringwhichcanbeinstalledtoallowfora
tighterfitshouldyouchoosetouseit,asthelensflangecanvaryslightlyfromcameratocamera.We
recommendinstallingtheBlurFixAirwithouttheoring.Ifthefitisacceptableforyourneedsthenoring
installationisnotnecessary.Ifyoudesireatighterfitorknowthatyouareusingthefilterinanextreme
vibrationenvironmentthenyoushouldinstalltheprovidedoringaccordingtotheinstructionsinoneofthe
followingsections.BesuretotightentheBlurFixAirbeforeyourfirstinstallation(seePreinstallation
Instructionsfordetails). 
FilterSelection
TheBlurFixAircomeswithyourchoiceoffilters.Theseincludeacircularpolarizer(CP),neutraldensity4
(ND4),orcombinationneutraldensity8(ND8)withCPfilter.FiltersareusedwiththeGoProtocombatone
orbothofthefollowingissues:glareandrollingshuttereffects.Glareiscommonlyfoundonthesurfaceof
waterandwindshields/windows.ACPfiltercanbeadjustedtocutdownonglareandiscommonlyusedin
fishingvideosoronthedashofaracecar.Theeffectcanbedramatic.Forinstance,infishingvideosaCP
filtercanmakethedifferencebetweenseeingyourcatchjustbelowthesurfaceorseeingonlysunlight
reflectedoffthewater'ssurface.Inaddition,CPfilterswillmaketheskyappearbluerandcausecloudsto
havemorecontrast.Whenusedinsnowyconditions,aCPfilterwilladdcontrast,allowingtheviewerto
distinguishfeaturesthatwouldnormallybeoverexposed.
NeutralDensityfiltersreduceoreliminatetheeffectsofrollingshutter,suchasthejelloeffectandpropblur.
Inhighvibrationenvironmentslikeaquadcopterplatform,thevideocommonlyappearstobeshotthrougha
bowlofclearjello.AnNDfilterslowsdowntheautomaticshutterspeedbyreducingtheamountoflightthat
thecameradetects.Thiswillsignificantlyreducethejelloeffect.NDfilterscomeindifferentlevelsoflight

reduction.DarkerNDfiltersshouldbeusedonbrighterdays(i.e.ND8)andlessdarkNDfiltersareusedon
moderatelybrightdays(i.e.ND4).Experimentingwithdifferentfiltersindifferentlightconditionsisthebest
waytodeterminewhichfilterisright.Propblurreferstotheartifactsthatcommonlyoccurwhenfilminga
propellerorrotorusingastockcamera.Thepropelleroftenisfragmentedandisnotwhat'sseenbythe
operatorinreallife.AnNDfilterusedinthesesituationsslowsdowntheshutterspeedandreducesor
eliminatestheseartifacts.Again,thisreductiondependsontheNDfilterratingandthelightingconditions.
ExperimentationisrecommendedtoselecttheoptimalNDfilter. 
PreInstallationInstructions
BeforeinstallingtheBlurFixAir,itisimportanttomakesurethatthetwopiecesoftheBlurFixAirare
screwedtogethertightly.TheBlurFixAirisatwopiecedesignthatallowsyoutotakethefilterframeapart
inordertocleanthefilterglasscompletely.Ifthetwopiecesarenotscrewedtogethertightlythenthe
piecescanunscrewthemselvesinahighvibrationenvironment(i.e.quadcopterorairplaneuse).Toensure
thetwopiecesdonotcomeapartinmidfilm,itisimportantthatyouscrewthepiecestogetherBEFORE
installingtheBlurFixAironyourcamera.Thisisdonebypressingthesmallestdiameterpieceagainstthe
bottomofarubbersoledshoeusingthepalmofyourhandandthenturningtheunitclockwise.After
touchingthesurfaceofthefilterglasswithyourhandyoushouldcleantheoutsidesurfaceusingthe
providedmicrofiberclothandalenscleaningsolution.Neverusethecameraasa"wrench"toholdthe
BlurFixAirwhileyouturntheoutsidepieceoftheframethiscandamageyourcamera.
ThefollowingimageshowsusingthebacksideofamousepadtotightentheBlurFixAir.


InstallingtheBlurFixAir
ToinstalltheBlurFixAir,pushitontotheGoPrountiltheframebottomsoutonthecamerabody.Never
rotatetheBlurFixAirwhileitisonthecamera.ThediameteroftheGoProlensbodymayvaryslightly.Ifthe
fitisnotastightasdesired,installtheincludedoringintheoringgroove.Thisisdonebyfirsttakingthe
twopiecesoftheBlurFixAirframeapart(seeDisassemblyofBlurFixAir).Taketheprovidedoringand
installitintheoringgroovelocatedontheinsideofthesmallerframepiece.Useyourindexfingertopress
theoringintothegroove.SlideyourfingerallthewayaroundtheinsideoftheBlurFixAirtomakesurethat
theoringisseated.BeforeputtingtheBlurFixAirbacktogether,installthesmallerpieceonthecameraby
itself.Makesuretheoringisnotpinchedandslipsoverthecameralensflange.Onceitslipsover,the
oringwillbeseatedproperlyandyoucanreassembletheunit.
DisassemblyoftheBlurFixAir
TheBlurFixAircanbedisassembledsothatthefilterglasscanberemovedandcleaned.Todisassemble,
pressthesmallestdiameterpieceagainstthebottomofarubbersoledshoeusingthepalmofyourhand
andthenturntheunitcounterclockwise.Itmaytakealotofpressuretogetenoughfrictiontospinthe
piecesapart,sodon'tbeshy.Oncethetwopiecesareapartthefilterglasswillfalloutofthefemalepiece,
somakesureyoudisassembletheBlurFixAiroverasurfacethatisconducivetothefilterglassdropping
out. 
AssemblyoftheBlurFixAir
TheBlurFixAirisassembledinjustthereverseasthedisassemblyinstructions.First,cleanthefilter
thoroughly(seeCleaningtheFilter).Next,ifthefilterisaCPfilter,makesureitisorientedproperly(see
DeterminingCircularPolarizerOrientation).Usingcarenottotouchthesurfaceofthefilter,dropthefilter
intothefemalepieceoftheBlurFixAir.Finally,screwthetwopiecesofthefilterframetogether.Tighten
thetwopiecesthoroughly.Thisisdonebypressingthesmallestdiameterpieceagainstthebottomofa
rubbersoledshoeusingthepalmofyourhandandthenturningtheunitclockwise.Aftertouchingthe
surfaceofthefilterglasswithyourhand,youshouldcleantheoutsidesurfaceusingtheprovidedmicrofiber
clothandalenscleaningsolution. 
CleaningtheFilter
DisassembletheBlurFixAir(seeDisassemblyoftheBlurFixAir).Usethemicrofiberpatchincludedinthe
tinfilterholderandSRP’slenscleaner(soldseparately)tocleanthefilterglassthoroughly.Reassemblethe
BlurFixAir(seeAssemblyofBlurFixAir). 

DeterminingCircularPolarizerOrientation
Apolarizedfilterisintendedtobelookedthroughinonedirection.Inotherwords,ifyouflipthefilteraround
andlookthroughitintheoppositedirection(regardlessofrotation)thepolarizationpropertiesarenot
effective.IfyoutakeyourBlurFixAiraparttocleanthefilteryoucancheckthepolarizerorientationas
follows:
1. HoldthefilterupbetweenyouandanLCDscreen(i.e.LCDcomputer,tv,orphonescreen).
2. Rotatethefilterandnotehowdarkthescreenbecomes.
3. Flipthefilteroverandrepeat.
4. Thefilterorientationthatcreatesthedarkestscreenindicatestheproperorientation.
Thefollowingphotosshowlookingthroughapolarizedfilterintheincorrect(left)andcorrect(right)
directions.Thefilterwasrotatedtoitsdarkestlevelwhenlookingthroughineachdirectionandtheseare
theresults.

Ifyoudon'thaveanLCDscreenhandybecauseyouareoutfilminganddon'thaveyourphoneonyou,then
youcanrepeatthestepswhileholdingthefilterbetweenyouandtheskyorwater.Lookthroughthefilter
onedirectionandturnthefilter360degrees.Thenflipthefilteroverandlookthroughitintheotherdirection
andturnit360degrees.Whicheverdirectionhasthemostdramaticchangesasyourotateitistheright
directiontolookthroughthefilter.Installtheglasssothatthecameraislookingthroughthefilterinthe
samedirection. 
HowtoSetPolarizationWhenFilming
RemovetheBlurFixAirfromtheGoProcamera.HoldtheBlurFixAirsothatyoucanseethroughitclearly.
RotatetheBlurFixAiruntilyouseethedesiredlevelofpolarization.Notetheorientationofthefilterusing

themarkingsonthesideoftheframe.ThemarkingsontheoutsideofthefilterincludetheSRPlogoand
thetypeoffilter(CPorND8/CP).InstalltheBlurFixAirontheGoProinthissameorientation. 
Asanexample,ifflyingaquadcopteroveralakeonasunnydaythevideographershouldfirstdeterminethe
directionthatthequadcopterwillbepredominatelyfilmingfrom.Heshouldthenorienthimselfsothatheis
lookingatthesurfaceofthewaterinasmuchthesameorientationaspossible.Holdingthefilteroutinfront
ofhim,heshouldrotatethefiltertothepointwhereglareonthesurfaceofthewaterisreducedthemost.
ThenwithoutrotatingthefilterwithrespecttothegroundhewouldnotewheretheSRPlogois,using
straightdownasthereference.NexthewouldpressthefilterontothecamerasothattheSRPlogoisatthe
sameorientationwithrespecttostraightdown. 
