Lighting Techniques — PhotoRobot Studio Reference

Lighting is half of every PhotoRobot capture. The hardware orchestrates the platform + cameras; lighting determines whether the captured imagery looks like an honest representation of the product or like a flat catalog tile. These reference manuals collect the lighting knowledge that PhotoRobot capture work depends on — written portably so they can migrate to photorobot.com as standalone product manuals.

What this reference is

A foundation library of lighting techniques used across the PhotoRobot studio range. Five core topics, each a standalone reference manual. Cert tracks (Operator Standard, Studio Manager Essentials, specialty tracks) link into these manuals rather than duplicating the content.

The reference is living content:

• Phase A (current) — published here on academy.photorobot.io as the working location. Cert track modules (currently SPCARP03 Carpet Lighting Discipline, with more to follow) link into these manuals.
• Phase B (planned) — content migrates to photorobot.com manuals where the PhotoRobot manuals team owns the canonical reference. Cert tracks re-link to photorobot.com URLs. This Academy reference is replaced with a redirect or a thin overview that defers to photorobot.com.

Until Phase B, customers + AI agents finding lighting content via search land here. Treat the writing as customer-facing — concrete, friendly, no jargon-for-its-own-sake.

Why lighting needs its own reference

Three reasons that drive this library:

1. Customers don’t typically know lighting. PhotoRobot operators come from many backgrounds — some have product-photography lighting fluency, most don’t. Without a reference, every cert track has to re-teach lighting fundamentals; with this reference, tracks defer to it + focus on track-specific application.
2. Lighting decisions cross every device. Raking light matters for carpets, for textured packaging, for metallic surfaces, for footwear with stitching detail. Continuous vs strobe matters for Catwalk video as much as for fast-spin carpet capture. Single-source reference avoids per-track drift.
3. PhotoRobot manuals team needs source material. photorobot.com manuals currently cover hardware + software, not technique. KH 2026-05-30 directive: write the technique reference, hand it to the manuals team, revise as the team integrates.

The library — five reference manuals

Read in any order, each is self-contained. SPCARP03 (Carpet Specialty Lighting Discipline) references all five; other cert tracks reference subsets.

Continuous vs Strobe Lighting

When to use continuous lighting (motion video, slow-motion, exposure metering by eye) vs strobe lighting (fast-spin product capture, high-power short-flash for crisp freeze). Mechanics of each, recovery times, colour temperature stability, exposure consequences. The decision that determines half of a session’s lighting setup.

Raking Light Technique

Low-angle illumination that reveals texture, pile direction, weave pattern, surface relief. Why standard overhead lighting flattens textured surfaces; how to position raking light for different sample types; combining raking with fill light without losing the effect. Primary use case: carpets + textiles, but applicable anywhere texture matters.

Studio Lighting Setups for PhotoRobot Sessions

From three-point foundation to PhotoRobot’s multi-light reality. Three-point (key + fill + back) is the universal product-photography model; PhotoRobot capture starts at four lights (subject + background pair for clean software background removal), scales to six (glass / transparent / 90° camera elevation), and eight or more for large turntables, automotive, and large subjects. Plus specialty techniques: showroom lighting for cars + reflective products, tent + contrast panels for jewelry, photographic paper gradients for stainless / polished metals, deep-zoom-ready high-aperture capture, non-stop synchronisation for production throughput.

Colour Temperature Management

Why colour temperature drifts across cameras + lighting fixtures + sessions, how to calibrate before each session, how to compensate for mixed-source lighting, white-balance discipline for multi-camera rigs. Essential for any session where colour fidelity matters (catalog, QC, automotive sample documentation).

Fibre-Specific Lighting Considerations

How different fibre materials interact with light — wool (matte, absorbent), synthetic (often glossy, reflective), blend (mixed character), natural-fibre (variable). Choosing lighting strategy per material, capture-time previews to verify, common artifacts per fibre type. Specific to carpet vertical but extends to fabric / textile / apparel materials.

How cert tracks reference this library

When you encounter a [Lighting Manuals] link in a textbook (e.g., “See the raking light manual for full reference”), the link drops you here. The track-specific material assumes you’ve read or can quickly reference the linked manual; the track doesn’t re-explain fundamentals.

This is the same pattern the rest of the Academy uses for photorobot.com manuals — the difference is, for lighting, the manuals are currently hosted here pending Phase B migration.

Currently referencing the library

• SPCARP03 — Lighting Discipline for Carpet Capture (forthcoming v0.51.0) — references all five manuals
• More cert tracks will adopt as content matures

How to use this reference

• As a student preparing for a session — read the relevant manual(s) for your upcoming capture type before the session. Lighting is easier to get right when you’ve thought through the decisions in advance.
• As an operator on the shop floor — use the reference manuals as a quick-lookup during session prep. Each manual ends with a decision checklist + common-problem table.
• As a Studio Manager scoping engagements — use the manuals to scope what lighting infrastructure the customer’s studio needs + to articulate lighting requirements to the customer’s IT / facilities team.
• As a customer evaluating PhotoRobot — the manuals show the depth of technique discipline that comes with a PhotoRobot deployment. Lighting isn’t a black box.

Contribution + maintenance

The manuals are maintained here until Phase B migration. Updates:

• Notice a gap, error, or out-of-date detail? Flag to KH or the Academy team — manual updates land in patch versions.
• New lighting technique emerges (LED matrix arrays, RGB studio kits, etc.)? Manuals can extend. Bring proposed additions to the team before writing — we keep the library tight.
• Phase B migration window — when the photorobot.com manuals team is ready to integrate, the Academy reference becomes a redirect / overview deferring to canonical photorobot.com URLs.

What this reference is not

• Not a comprehensive textbook on photography lighting. Reference scope is what PhotoRobot capture work specifically requires. For broader photography lighting (architectural, portrait, commercial), other resources exist + are better.
• Not equipment buying advice. The manuals discuss types of fixtures (continuous, strobe, modifiers) but don’t recommend specific brands or models — equipment selection depends on customer’s budget, studio layout, and existing inventory. Hardware Specialist + Studio Manager certs cover equipment evaluation.
• Not a substitute for hands-on practice. Reading the manuals prepares you for the decisions; hands-on time in the studio is where the discipline actually develops.

Next steps

• First time here? Start with Studio Lighting Setups for PhotoRobot Sessions — three-point foundation + PhotoRobot’s multi-light reality (4 / 6 / 8+ lights, showroom approach, tent + panels, stainless techniques, deep zoom, non-stop). The most broadly applicable, applies to most non-specialty captures.
• Carpet-vertical operator? Read Raking Light Technique + Fibre-Specific Lighting Considerations — these two carry most of the carpet capture lighting decisions.
• Doing video / motion work (Catwalk track)? Continuous vs Strobe Lighting is foundational.
• Colour-accuracy-critical session ahead (QC, automotive sample documentation)? Colour Temperature Management is essential before session start.
