Camera-to-Subject Perspective Physics
See firsthand why standing too close widens noses and hides ears, while stepping back with longer focal lengths flatters bone structure.

✓ Free Online Intro Included
Optical Focal Lengths in Practice: 24mm, 35mm, 50mm & 85mm
Test all four classic focal lengths side-by-side on the same portrait and interior subjects in studio before investing in expensive glass.
Online spec sheets and chart reviews never show how working distance changes facial proportions inside a compact room versus an open street. By shooting matched head-and-shoulder and environmental frames across 24mm, 35mm, 50mm, and 85mm in person, you see perspective geometry, background compression, and prime-versus-zoom handling with your own eyes.

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.
Controlling Background Scale & Compression
Pull distant architectural textures close behind your subject at 85mm, or weave room context into documentary storytelling at 35mm.
Fast f/1.4 Primes vs f/2.8 Workhorse Zooms
Weigh the two-stop low-light and bokeh advantage of primes against the single-body speed of a 24–70mm zoom for events and client shoots.
Sensor-Matched Optical Roadmap
Translate full-frame focal lengths accurately onto APS-C crop bodies if needed, and inspect used or third-party lenses without guesswork.
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
Matched-Framing Four-Lens Portrait Comparison
Photograph the exact same tight headshot and waist-up frame at 24mm, 35mm, 50mm, and 85mm to compare facial geometry side-by-side.
- Measuring real indoor working distance required for each focal length
- Comparing nose-to-cheekbone proportions, ear visibility, and bokeh circles
- Calculating exact APS-C 1.5x and 1.6x crop field-of-view equivalents
Topic 02
Environmental Context vs Telephoto Subject Isolation
Practice composing clean 24mm and 35mm environmental frames without corner limb stretch alongside 85mm portrait isolation.
- Keeping subjects out of extreme 24mm corners to avoid distortion
- Why pairing 35mm and 85mm covers ninety percent of editorial and brand work
- Adjusting minimum shutter-speed floors as focal length gets longer
Topic 03
Optical Flaws, Focus Breathing & Minimum Focus Distance
Test close-up reproduction ratios, longitudinal chromatic aberration (`LoCA`), flare resistance, and video focus breathing across lenses.
- Spotting green/magenta color fringing on high-contrast edges at f/1.4–f/1.8
- Testing close-focus capability for wedding rings, food, and detail B-roll
- Evaluating AF motor noise and focus-breathing shifts for hybrid video shooters
Topic 04
100% Calibrated Monitor Audit & Smart Buying Inspection
Review your captured RAW files on a studio monitor and learn how to inspect any new or pre-owned lens in Toronto for decentering.
- Four-corner brick/chart sharpness test to catch decentered lens elements
- Comparing native flagship glass against modern Sigma Art and Tamron options
- Structuring a lean two-lens kit tailored to your genre and budget
Course Reference Overview
Focal Length Optical Character Reference
Core practical benchmarks and standards covered as part of this course's curriculum.
| Full-Frame Focal | APS-C Equivalent | Strongest Studio/Field Role | Primary Optical Caution |
|---|---|---|---|
| 24mm Wide | 16mm on APS-C | Interiors, architecture, dynamic group energy | Never frame tight headshots under 1.5m |
| 35mm Documentary | 23mm on APS-C | Environmental portraits, cafés, street stories | Keep camera level to avoid leaning walls |
| 50mm Standard | 33–35mm on APS-C | Natural half-body portraits, products, travel | Requires deliberate light & composition |
| 85mm Short Tele | 56mm on APS-C | Headshots, beauty, melting busy backgrounds | Demands 3m–5m indoor room backing space |

Program FAQ
Common Questions
What if I currently only own an 18–55mm or 24–105mm kit zoom lens?
Taking this course before buying new glass is the smartest timing. You bring your camera body and kit zoom, test fast primes alongside it in our Toronto studio, and leave knowing the exact focal length that fits your eye. We confirm your camera mount during the Free Online Intro Session.
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, or can I get just the PDF guide?
There is zero upfront package commitment: live sessions are booked flexibly session-by-session ($69 CAD/hr online or $99 CAD/hr in-person). If you prefer a self-paced written guide instead of live coaching, a standalone $39 CAD PDF option can also be requested for this topic.
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.
