3. Operation

3.1 Overview



Withmacrophotographyalltoooftenpictureshaveashallowdepthoffield(DOF).Thisis

whereStackShot(andwidelyavailablefocus‐stackingsoftware)shine.StackShotallowsprecise

controloveracamera’spositionintendedforusewithmacrophotography.Itautomatesthe

processoftakingseveralpicturesinincrementalsteps.Thesubsequentimagesarethen

processedbyfocus‐stackingsoftwaretomergetheshallowDOFimagesintoasinglecrispand

highlydetailedpicture.Whilethissameprocesscanbeaccomplis hedmanually,gettingprecise

stepsisdifficult,timeconsuming,andfrustrating.Decreasingthetimespenttakingtheimages

alsoallowsyoutofocus‐stackthingsthatjustwouldn’tcooperateorstaystilllongenough.By

combiningasimpleuser‐interfacewithbehind‐the‐scenesextremeflexibility,StackShotisa

necessityforanyseriousmacrophotographer.



CAUTION:Alwayskeepyourbody,cables,andequipmentclearoftherailwhileitisinmotion.

Beawareoftheenvironmentyouareoperatingin.Thecenterofgravitywillchangeas

StackShotmovesthecamera.Movingtherailcanpotentiallycauseatippinghazard.Besure

thatyourtripodissecuredandbalancedproperlytopreventdamagetoequipment.Monitor

yourcamera,lens,andotherequipmentatalltimeswhile therailismovingtopreventdamage

toyourequipment.Themotorcablemayposeasatrippinghazard.Usecaution.



3.2 TheUserInterface



TherearesevenbuttonstocontrolStackShot.



TheSELECTbuttonmovesthecursor(“>”indicator)fromlinetolineonthedis play.TheUPand

DOWNbuttonadjustthevaluesforeachline.CONFIGwilldisplaya(lengthy)listofuser‐

specifiedconfigurations.FWDmanuallymovesthemotorassemblyforwardwhileBACKmoves

itbackward.SHUTTERwillmanuallyfiretheshutteronthecamera.



Note:Ifthemotorismovingorasequenceisactive,anybuttonpresswillstopthemotor

immediatelyandaborttheactivesequence.



Usersettingswillbesavedacrosspowercycles.



Thedifferentmodesofoperationarelistedinthefollowingsections.

3.3 GlobalConfiguration

ToenterStackShot’sGlobalConfiguration,quicklypressandreleasetheCONFIGbutton.The

displaywillchangeandlisttheavailableuserconfigurations.Toreturntothemainscreenpress

theCONFIGbuttonagain.Thedifferentconfigurationoptionsarediscussedbelow.Allof

thesesettingsaremaintainedwhenusingthe“Load/SaveSettings”option.Thisprovides

maximumflexibilityand easeofuse.Thelastsettingsusedarealsoretainedoverapowercycle

foryourconvenience.



3.3.1 PicturesperStep

StackShotdefaultstoone pictureperstep.Youmay,however,increasethenumberof

pictures(“#pics”)takenateachstep.Thisgivesyoutheoptionofdoingexposure

bracketing,mirrorlockup,orothercameraeffects.Validvaluesarefrom1–1000.Thisis

notthetotalnumberofpicturestaken–justhowmanyateachstep.
