Q1 multiple-choice · continuous-vs-strobe Which of the following workflows REQUIRES continuous lighting (not strobes)?
Explanation: Strobes fire briefly — they cannot illuminate the full duration of a video clip. Video requires continuous (LED) lighting. All other listed workflows benefit from strobes’ fast recharge + tight color temperature control.
Q2 multiple-choice · strobe-recommendation Which strobe brand does PhotoRobot recommend for production studios?
Explanation: PhotoRobot’s recommended strobe is the Broncolor Siros 400/800 series with WiFi/RFS2 . CAPP integrates with Broncolor directly — no separate driver installation, no manual control app once paired. Other brands can be used in dumb-trigger mode but lose the integrated workflow.
Q3 multiple-choice · 4-light-template In the standard 4-light template, which position’s role is to soften shadows created by the dominant light?
Explanation: The Fill light is positioned opposite the Key and at lower intensity. It reduces the contrast of shadows cast by the Key without overpowering the dominant lighting direction. The 4 positions are: Key (dominant), Fill (shadow softener), Back/rim (edge separation), Background (backdrop illumination).
Q4 multiple-select · freemask · weight 2 Which of the following are TRUE about Freemask? (Select all that apply.)
Explanation: Freemask is a 2-frame capture workflow: front-lit frame produces the main image, back-lit frame produces the mask (silhouette against blown-out white). CAPP combines them into an alpha-channel PNG. The front and back lights must be separate fixtures because CAPP controls them independently. Back light spilling onto the front of the subject creates a halo in the mask.
Q5 scenario · placement-vs-power · weight 2 A new operator complains: “I’m getting hard, dark shadows on the side of the product. I tried raising the key light power from 50% to 80% — it just made the shadow darker.”
Explanation: Lighting placement (position + angle + distance from subject) dominates lighting power as the determinant of shadow quality. Raising the key light power doesn’t soften the shadow — it just intensifies it. Adding more lights without addressing placement creates a mess. Repositioning the fill light closer / opposite the key is the canonical fix.
Q6 multiple-choice · rail-system Which ceiling rail system does PhotoRobot recommend as the canonical mount for studio lights?
Explanation: PhotoRobot’s canonical recommendation is FOMEI ceiling rail systems in 3 kit sizes. Tracks mount to the ceiling; trolleys slide along tracks; pantographs lower lights to any height. Advantages over floor stands: no tripping hazards, cleaner workspace, faster repositioning, cleaner cable routing.
Q7 multiple-choice · pantograph-load What is the maximum load a single FOMEI pantograph (FY7933) can support?
Explanation: A single FOMEI pantograph supports up to 15 kg . A Broncolor Siros 800 alone weighs ~2 kg, well within range — but large softboxes, fresnel attachments, and other modifiers can quickly approach the limit. Verify total weight before adding hardware to existing rigs (B02 Safety territory).
Q8 multiple-choice · broncolor-trigger Which Broncolor component is mounted on the camera to wirelessly trigger the strobes?
Explanation: The Broncolor RFS 2.1 transceiver operates at 2.4 GHz and mounts to the camera hot-shoe. It fires the strobes wirelessly when the camera shutter triggers. The BronControl app is for management (intensity, pairing) — not triggering.
Q9 true-false · capp-integration After initial WiFi pairing of Broncolor Siros, day-to-day power/standby/modeling-light adjustments are made directly in CAPP — operator does not need to use the BronControl app for routine work.
Explanation: Once paired, CAPP controls Broncolor lights directly — power level, modeling light, standby — all visible in CAPP’s Hardware Configuration > Lights area. BronControl is used only for initial WiFi setup and edge cases. This is one of the operator workflow advantages of PhotoRobot + Broncolor integration.
Q10 multiple-choice · scopes-presets A studio operator manually adjusts 6 lights for “Apparel-Standard” vs. “Apparel-Freemask” workflows, taking ~90 seconds per switch. They switch 12 times per day.
Explanation: Scopes + Presets capture the entire lighting state (every light’s power, modeling, standby) under a named label. Operator selects a preset, all lights snap to the saved configuration. 12 switches × 90 seconds = 18 minutes / day saved per operator = ~75 hours / year.
Q11 multiple-choice · mixing-tech A studio captures both stills (mornings) and product videos (afternoons). What is the recommended setup?
Explanation: Two separate workspaces (B05) with their own lighting scopes/presets. Strobe + continuous fired together produces unpredictable exposure (strobe pulse adds on top of ambient LED). Pick the right technology per workflow, configure each as a workspace, switch workspaces between morning stills and afternoon video work.
Q12 true-false · network-config Broncolor Siros lights communicate over 2.4 GHz WiFi and ideally should be on a separate subnet from the studio’s main network.
Explanation: PhotoRobot’s recommended Broncolor network setup uses a separate subnet (tested with Mikrotik RB1100AHx4 router + TP-Link TLWR802N access point). Putting Broncolor lights on the studio’s main corporate WiFi creates interference and reliability issues. This is B03 (Network Setup) territory and a network-specialist responsibility.
