10-Bit 4:2:2 Color Subsampling Precision
Compare 8-bit 4:2:0 against 10-bit 4:2:2 files side by side on a studio monitor to see why doubled horizontal color data keeps fine hair strands intact.

Studio Green Screen Lighting & Clean Chroma Keying
Eliminate frizzy green hair halos and chattering edges by lighting flat 50 IRE backdrops in 10-bit 4:2:2 and pulling natural multi-pass composites.
Poor green screen work gives itself away on the very first frame, usually because the speaker sat half a meter from a wrinkled cloth lit by the exact same softbox lighting their face. That single shortcut creates dark backdrop corners, radioactive green bounce under the chin, and jagged 4:2:0 edges that chew through curly hair. This course teaches repeatable studio chroma discipline from objective False Color backdrop calibration to two-pass keying and realistic background light wrap.

Course Learning Pillars
Core Capabilities Developed in This Course
Every learner starts from a different background. These are the core capabilities this course develops, paced to your goals across the sessions we plan together.
Flat 48–55 IRE Backdrop Calibration
Light collapsible, paper, or cyclorama green screens symmetrically from the sides until False Color displays one solid exposure band edge to edge.
Physical Distance & Green Spill Blocking
Create separation between backdrop and speaker, lay dark floor duvetyne, and shape subtle hair rim light so green bounce disappears before post.
Perspective, Light Angle & Light-Wrap Composites
Match camera focal length, lens height, and key-light direction to your target virtual plate, finishing edges with subtle optical light wrap and grain.
Course Syllabus
Core Concepts & Topics Covered
Below are the main concepts and topics covered in this course. In your Free Online Intro Session, we align the exact depth and number of sessions to your experience and goals.
Topic 01
Backdrop Surface Prep, Symmetrical Lighting & False Color
Setting up wrinkle-free chroma surfaces and dialing pure, flat green saturation before switching on a single subject fixture.
- Why overexposing green cloth to 75+ IRE washes out chroma purity and floods the room with bounce
- Comparing steamed tensioned fabric against matte chroma paper rolls in compact spaces
- Adjusting shutter speed (1/80s–1/100s) when hand gestures need crisp keyable edges
Topic 02
Independent Subject Lighting, Eyeglasses & Spill Control
Lighting curly hair, blonde strands, reflective eyeglasses, and dark suits cleanly in front of an active chroma backdrop.
- Flagging backdrop fixtures with barn doors or V-flats so stray light never flares the lens
- Laying black floor rugs beneath the talent to kill upward green reflection on jawlines
- Small-room adaptations when total depth behind the chair is limited to 1.2–1.5 meters
Topic 03
Matching Camera Optics & Lighting to Virtual Background Plates
Choosing background plates ahead of the shoot so horizon line, window direction, and depth of field feel physically believable.
- Aligning tripod height and 35mm vs 50mm perspective with architectural background lines
- Matching warm vs cool key-light motivation to the virtual room's window or lamp side
- Recording lens metadata and gray/color chart frames for accurate post matching
Topic 04
Multi-Pass Keying, Despill Refinement & Edge Light Wrap
Pulling transparent keys in DaVinci Resolve 3D/Delta Keyer, After Effects Keylight, and Premiere Ultra Key without plastic-looking skin.
- Building a two-pass key: rock-solid core matte combined with a delicate soft hair edge matte
- Natural despill grading that removes green fringes while preserving skin warmth and blue eyes
- Applying subtle background edge light wrap, matched lens blur, and sensor grain unity
Course Reference Overview
Studio Chroma Key Technical Reference
Core practical benchmarks and standards covered as part of this course's curriculum.
| Technical Variable | Common Amateur Flaw | Studio Chroma Standard | Composite Impact |
|---|---|---|---|
| Color Sampling & Bit Depth | Compressed 8-bit 4:2:0 recording | 10-bit 4:2:2 internal or ProRes at base ISO | Clean individual hair strands without stair-stepping |
| Backdrop Luminance | Uneven 25–80 IRE hotspots and corner shadows | Flat 48–55 IRE verified on False Color | Single-range chroma selection without noisy holes |
| Talent-to-Screen Distance | Standing 40–60cm directly against the cloth | 2.0m–3.0m separation (or dimmed 42 IRE compact setup) | Zero body shadows on screen and clean shoulder edges |
| Edge Integration | Hard cutout pasted onto a mismatched sharp photo | Soft edge matte, optical blur, and 2–4px light wrap | Natural depth that reads like a real room shoot |

Program FAQ
Common Questions
What if my home office or clinic room is compact and I only have about 1.2 meters behind my chair?
Small rooms are very common for course creators and specialists. During the Free Online Intro Session we review your room dimensions, and in the course we practice the compact-room formula: lowering backdrop exposure slightly to 42 IRE, hanging negative black flags on the sides, and adding a gridded rim light to neutralize close-wall bounce.
How does the Free Online Intro Session work, and how many sessions will I need?
Every course begins with a Free Online Introductory Session where we review the core syllabus together, evaluate your current background and goals, and map out how many sessions you actually need and whether continuing Online ($69 CAD/hr) or In-Person ($99 CAD/hr) suits you best. Session count is never a rigid one-size-fits-all number; it adapts to your own level and pace.
Do I have to commit to a multi-session package upfront?
Never. There is zero upfront package commitment: once your free online intro session maps out your path, any coaching sessions you choose ($69 CAD/hr online or $99 CAD/hr in-person) are scheduled flexibly session-by-session at your own pace.
Are courses taught in English, Persian (Farsi), or bilingual?
Your choice: every session with Iman Adlkhah can be conducted 100% in English, 100% in Persian (Farsi), or naturally bilingual with industry terminology.
