Parallax Moves Explained

Using Orbit and Reveal Shots for Dynamic Lessons

One of the simplest ways to make educational videos feel alive is to introduce controlled camera movement. Not shaky, not distracting — just enough motion to create depth and guide attention.

At Philip M Russell Ltd, we regularly use parallax moves — especially orbit and reveal shots — in science lessons, equipment demonstrations, sailing videos, and workshop filming. When used carefully, these moves help explain ideas more clearly and keep viewers engaged without overwhelming them.

---

What Is Parallax?

Parallax is the apparent shift between foreground and background objects as the camera moves.
Nearby objects appear to move faster than distant ones.

Your brain uses this effect to judge depth and spatial relationships, which makes parallax incredibly powerful for teaching.

In video, parallax:

• adds depth to flat scenes

• separates subject from background

• guides the viewer’s eye

• maintains interest during explanations

It’s movement with purpose.

---

The Orbit Shot

An orbit shot moves the camera smoothly around a subject while keeping it roughly centred in frame.

Why It Works for Teaching

Orbit shots are excellent for:

• lab equipment walkthroughs

• 3D objects (models, apparatus, organs, engines)

• explaining how parts relate spatially

• sailing hardware or deck layouts

• showcasing instruments or control panels

The subject stays constant while the background changes — reinforcing structure and form.

Teaching Example

When explaining a piece of apparatus, an orbit shot helps students understand:

• where components sit relative to each other

• how access points connect

• what’s fixed and what moves

It’s far clearer than static shots alone.

---

The Reveal Shot

A reveal shot starts with something blocking the view, then moves to uncover the subject.

Why Reveals Are Powerful

Reveal shots are ideal for:

• introducing a new concept

• moving from context to detail

• showing “before and after”

• transitioning between lesson sections

• uncovering results of an experiment

They naturally create curiosity.

Teaching Example

In science videos, we often:

• start behind equipment

• slide past a bench edge

• move from wide to close

• reveal data, graphs, or reactions

The motion mirrors the learning journey: from unknown to understood.

---

Keeping It Subtle (and Professional)

For lessons, parallax should support clarity — not show off.

Our rules:

• move slowly

• keep motion smooth

• stop moving when explaining key points

• avoid constant movement

• prioritise stability over speed

The camera should feel intentional, not restless.

---

How We Achieve Parallax Simply

You don’t need expensive gear.

We use:

• handheld micro-movements with stabilisation

• monopods for controlled arcs

• sliders for short linear reveals

• slow gimbal moves when space allows

• careful post-stabilisation in DaVinci Resolve

Even a few centimetres of movement can create effective parallax.

---

Why This Matters for Learning

Parallax shots:

• help students visualise spatial relationships

• keep attention during explanations

• reduce cognitive overload by guiding focus

• make lessons feel more “present” and real

• improve retention compared to static framing

Motion becomes part of the explanation.

---

The Takeaway

Parallax isn’t about flashy filmmaking — it’s about clarity through movement.
Orbit shots help learners understand structure.
Reveal shots help ideas unfold naturally.

Used carefully, these techniques turn static lessons into engaging, spatially clear explanations — perfect for science teaching, sailing instruction, and technical demonstrations.

Move the camera with purpose, and the lesson moves with it.

An Infrared View Outside My Home

How a multispectral camera and a visible-light cut filter transform the familiar world

When you remove visible light from a camera, the world changes completely.

Using a multispectral camera fitted with a visible-light cut filter, I recently photographed the area around my home purely in infrared. The results were striking. Trees glowed, skies darkened, brickwork changed tone, and surfaces that looked identical to the naked eye suddenly separated into distinct materials.

Infrared imaging doesn’t just look different — it reveals how the world actually interacts with light beyond human vision.

---

What the Filter Does

A visible-light cut filter blocks everything we normally see and allows infrared wavelengths to reach the sensor.
This means the camera is no longer recording colour in the everyday sense — it’s recording reflectance properties of materials in the IR range.

What looks “bright” or “dark” is no longer about colour, but about structure, moisture content, and surface chemistry.

---

What Changes in Infrared

Vegetation Becomes Bright

Leaves and grass reflect IR extremely strongly.
Healthy vegetation appears pale or even white, a phenomenon known as the Wood Effect.

This immediately opens discussions around:

• plant structure

• chlorophyll

• reflectance vs absorption

• how satellites monitor crop health

Skies Darken Dramatically

Clear skies absorb much of the infrared, producing deep, dark tones.
Clouds remain bright, increasing contrast.

It’s an excellent way to demonstrate:

• atmospheric scattering

• wavelength-dependent absorption

• why different parts of the spectrum behave differently

Buildings Reveal Materials

Brick, stone, tarmac, roofing felt and painted surfaces all reflect IR differently.
Walls that look identical in visible light suddenly separate into layers of information.

This links directly to:

• material science

• thermal behaviour

• energy efficiency

• why thermal and IR cameras are useful in building surveys

Water and Moisture Stand Out

Wet areas absorb IR and appear darker.
This makes infrared imaging useful for:

• damp detection

• leak tracing

• environmental studies

Even garden paths and walls tell a different story after rain.

---

Why This Is So Valuable for Teaching

Infrared images are perfect teaching tools because they challenge assumptions.

Students quickly realise:

• colour is not a property of objects

• vision is limited

• instruments extend human senses

• data depends on wavelength

• “seeing” depends on physics

This single imaging technique links to:

• physics (electromagnetic spectrum)

• biology (plant reflectance)

• chemistry (surface interactions)

• geography (remote sensing)

• environmental science

• photography and imaging technology

One walk outside becomes a cross-curricular lesson.

---

Challenges of Infrared Photography

Infrared imaging isn’t point-and-shoot.

• Focusing can shift in IR

• Exposure times are longer

• Noise increases

• Filters block a lot of light

• White balance must be rethought

• Lenses behave differently

But these challenges are exactly what make it valuable in education — students see theory applied in practice.

---

The Takeaway

An infrared view of the everyday world reminds us that reality is far richer than what our eyes detect.
By using a multispectral camera and a visible-light cut filter, ordinary scenes outside the home become powerful demonstrations of physics, materials science and environmental behaviour.

The world hasn’t changed —
we’ve just changed how we look at it.

 

A Homemade Ripple Tank

Proof that great physics doesn’t need expensive equipment

Ripple tanks are a brilliant way to teach wave behaviour — reflection, refraction, diffraction, interference — but commercial ripple tanks are expensive, fragile, and often locked away in cupboards “for special occasions”.

Some of our students want to recreate a ripple tank at home. They are easy to create using

• the clear lid of a “Really Useful Box”

• a few books for the lid to rest on

• a torch

And it works beautifully.

---

The Simple Setup

What We Use

• Clear plastic lid (flat, rigid, transparent)

• Books to raise the lid off the bench

• Torch or LED light underneath

• White paper or bench surface to project onto

• A dropper, finger, ruler, or vibrating source to create waves

• A shallow layer of water — just a few millimetres

The lid becomes the water surface, the books provide clearance for light, and the torch projects wave patterns onto the bench below.

No wiring.
No motors.
No specialist parts.

---

What Students Can See Instantly

1. Circular Waves

A fingertip tap or dripping water shows clean circular wavefronts spreading out from a point source.

2. Reflection

Place a ruler or straight edge in the water and observe waves reflecting with angle of incidence = angle of reflection.

3. Refraction

Create shallow and deep regions by tilting the lid slightly or adding a submerged object.
Wave speed changes are immediately visible.

4. Diffraction

Two obstacles with a gap between them demonstrate diffraction clearly — even better when the gap is close to the wavelength.

5. Interference

Two wave sources (two fingers or droppers) produce clear constructive and destructive interference patterns.

All of this from a plastic box lid and a torch.

---

Why This Works So Well for Teaching

Low Cost = High Access

Because it’s cheap, you can:

• let students try it themselves

• repeat experiments without worry

• run it in small groups

• recreate it at home

No “teacher-only” equipment.

Nothing to Break

If the lid scratches or the torch fails, replacements are trivial.

Concepts Over Complexity

Students focus on the physics, not on how the apparatus works.

Perfect for Filming

The projected patterns are ideal for:

• slow-motion video

• time-lapse

• overlays and annotations

• online lessons from the studio

It also makes an excellent visual for social media clips.

---

Extending the Experiment

With a few extras, the same setup can be used to explore:

• wavelength measurement

• wave speed

• frequency vs spacing

• damping

• superposition

• energy transfer

• analogy with light waves

Add a ruler, stopwatch, or camera — and suddenly you’re doing GCSE and A-Level physics with real data.

---

The Teaching Message

This experiment reinforces an important lesson for students:

Good science is about ideas, not expensive equipment.

If you understand the principle, you can demonstrate it with whatever you have available.

That’s a powerful message for learners — and teachers.

---

The Takeaway

A ripple tank doesn’t need motors, strobes or specialist trays.
A clear plastic lid, a torch and a bit of water are enough to reveal some of the most beautiful and important ideas in wave physics.

Simple.
Affordable.
Effective.

Exactly how practical science should be.

 

Run-and-Gun Checklists
What to Pack for Unpredictable Shoots (Rain, Wind, Low Light)

Run-and-gun filming is where preparation truly pays off.
When you’re shooting sailing at UTSC, science demonstrations outdoors, school events, wildlife passing by, or a spur-of-the-moment corporate clip, there is rarely time to plan, stage, or reset. The weather changes, the light changes, the subject moves — and you have to keep up.

At Philip M Russell Ltd, we rely on a run-and-gun checklist to ensure nothing essential is left behind. A single forgotten item can ruin a shoot.
Here’s what goes into our grab-bag for unpredictable filming conditions.

---

1. Weatherproofing Essentials

Rain Gear for Cameras

• Rain covers for mirrorless bodies

• Waterproof bag for action cameras

• Clear plastic emergency poncho (cheap but life-saving)

• Microfibre cloths for constant lens drying

Weather Protection for People

• Packable waterproof jacket

• Cap to keep rain off glasses/EVFs

• Hand warmers for winter shoots

Lens Protection

• UV filter or protector

• Rubber hoods that won’t catch wind

• A lens cloth in every pocket

Rain is the enemy of clarity — and electronics — so redundancy matters.

---

2. Wind-Proofing Tools

Wind ruins audio before it ruins anything else.

Audio

• Proper deadcats (not the tiny foam covers)

• Compact shotgun mic for directionality

• Lavalier mics with fur covers

• Gaffer tape for hiding lavs under clothing

Camera Stability

• A small monopod

• Additional grip strap

• Wind-resistant tripod if filming on a pontoon or the riverbank

For river filming at UTSC, we also carry extra tethering straps for cameras on the Whaly.

---

3. Low-Light Survival Kit

Lighting

• On-camera LED panel

• USB-powered mini light

• Warm/cool filters for colour balance

Battery Strategy

Low light = long exposures = more battery drain.
So we carry:

• spare camera batteries

• USB-C PD power bank

• spare AA/AAA for audio recorders

Focusing Aids

• Small pocket torch with a warm beam

• Laser-safe focus target (no harm to sensors)

Low light is manageable as long as you can see what you’re focusing on.

---

4. The “Unpredictable” Essentials

Action Camera

When the main camera can’t go into the rain, the GoPro or Insta360 Ace Pro can.

ND Filters

For bright moments between the clouds.

Lens Wipes & Cloths

Always more than you think you need.

SD Cards and a Spare Reader

Storage fails at the worst possible moment.

Small Toolkit

• mini screwdriver

• Allen keys

• spare quick-release plate

• Velcro ties

• gaffer tape (the universal fixer)

Emergency Audio Backup

• A tiny pocket recorder (Zoom H1n style)

• Clip-on lav mic

Just in case your main system fails or the wind overwhelms your shotgun mic.

---

5. Personal Comfort Items (often overlooked)

• Water bottle

• Muesli bar or energy snack

• Thin gloves that still allow camera operation

• Glasses cleaning spray

• Notebook and pen (still useful even with phones!)

If you are uncomfortable, your filming will suffer.

---

6. The “Tech Core” We Never Leave Without

• Main camera

• Lightweight versatile lens (24–70mm equivalent)

• Small telephoto if wildlife or sports likely

• Action camera

• Shotgun mic

• 2× lav mics

• LED light

• Batteries + power bank

• ND filters

• SD cards

• Microfibre cloths

That’s the minimal, go-anywhere setup.

---

The Takeaway

Run-and-gun filming is all about readiness.
You can’t control the weather, the light or the moment — but you can control what’s in your bag. With a solid checklist, you stay flexible, resilient, and always able to tell the story, whether it’s a science experiment, a sailing race or an unexpected moment worth capturing.

When the shoot is unpredictable, your preparation becomes your superpower.

 

Vectors, Logs and Errors — Teaching Maths Through Real Experiments

Why hands-on science is the perfect classroom for applied mathematics

Maths becomes far more meaningful when students see it working inside a real experiment.
At Philip M Russell Ltd, whether we’re running physics demos, environmental measurements, PASCO sensor work, or chemistry investigations, we use experiments to teach the mathematics behind them — especially vectors, logarithms, and error analysis.

When formulas move off the page and into the lab, students finally understand why these ideas matter.

---

Teaching Vectors Through Experiment

1. Forces in Equilibrium

A simple force table or three-spring setup shows that forces aren’t just numbers — they have direction.
Students learn to:

• break forces into components

• add vectors head-to-tail

• predict equilibrium points

• measure discrepancies between theoretical and experimental results

2. Motion and Velocity Vectors

PASCO SmartCarts or video analysis help demonstrate:

• velocity as a vector

• turning acceleration into vector changes

• how direction changes even at constant speed

Perfect for explaining why sailors talk about apparent wind, or why drones drift in crosswinds.

3. Field Vectors

Magnetic field mapping or electric field plate experiments teach:

• vector fields

• direction of force lines

• superposition

Students physically see vector addition happen in space.

---

Teaching Logarithms Through Data

Students often struggle with logarithms until they realise how often nature behaves logarithmically.

1. Radioactive Decay & Half-Lives

A Lascells cloud chamber or decay simulation demonstrates that:

• exponential decay becomes a straight line on a log plot

• ln(N) vs time removes curvature

• the gradient gives decay constant

Logs suddenly become a tool, not a hurdle.

2. Sound Intensity

Decibels are defined logarithmically.
Using a sound sensor, students see how:

• doubling intensity ≠ doubling dB

• logs help us compress huge dynamic ranges

Great for linking physics to music and video production.

3. pH Calculations

Acid–base experiments reveal that:

• pH is a logarithmic scale

• small concentration changes create big pH shifts

• titration curves simplify when plotted using log concentration

Pairing this with your DIY Arduino pH meter makes the maths very real.

---

Teaching Errors Through Measurement

Every experiment is an opportunity to teach uncertainty, precision, and propagation of error.

1. Random vs Systematic Errors

Using repeated measurements with SmartCarts or light gates helps students see:

• scatter around a mean

• bias from misaligned equipment

• the importance of calibration

2. Percent Uncertainty

A metre ruler, thermometer, or electronic balance lets students calculate:

• absolute error

• fractional error

• percentage error

They learn that no measurement is perfect — only quantified.

3. Error Bars on Graphs

When plotting Hooke’s Law or Ohm’s Law, students add:

• vertical error bars for measurement variation

• horizontal bars for instrument uncertainty

Seeing error bars helps them judge whether theoretical models match reality.

4. Propagation of Errors

When combining measurements (e.g., power = IV), students explore:

• how uncertainties combine

• why small errors can grow quickly

Excellent preparation for A-Level and university science.

---

Why Experiments Make Maths Easier

Because they answer the question students always ask:

“When will I ever use this?”

In the lab, the answer is obvious:

• Vectors explain forces, fields and motion.

• Logs linearise curved data.

• Errors separate good science from guesswork.

Students don’t just learn maths — they experience it.

---

The Takeaway

Vectors, logs and errors aren’t abstract topics.
They are the mathematical language of experiments.
By teaching them through real measurements, we give students deeper understanding, stronger skills, and the confidence to analyse the world around them.

Hands-on experiments turn maths into meaning.

 

Playing VST Modules on the Synth Through Gig Performer

Bringing software instruments to life with real performance controls

One of the most exciting upgrades in the Philip M Russell Ltd music workflow has been integrating VST instruments directly with the Wersi organ, synthesiser and MIDI controllers using Gig Performer.
Instead of treating software instruments as something you click with a mouse, Gig Performer turns them into playable, expressive, performance-ready sounds — just like hardware.

The result is a hybrid setup where the warmth and feel of a real synth meet the limitless sound palette of modern virtual instruments.

---

Why Use Gig Performer?

Gig Performer acts as a live VST host, allowing you to:

• load multiple VST instruments and effects

• switch sounds instantly

• route MIDI between keyboards and modules

• build performance “panels” with knobs, sliders and buttons

• map physical controls to software parameters

• set up complex splits, layers and pedal assignments

• run everything with extremely low latency

For science video soundtracks, organ accompaniments, experimental sound design or background beds for educational clips, it’s a huge upgrade.

---

Instead of playing a VST from a laptop keyboard, Gig Performer lets you:

• use the Wersi manuals to trigger soft synths

• use the synth’s pitch bend and modulation to shape sound

• assign expression pedals to filters, volume or effects

• blend hardware voicing with Kontakt libraries, Arturia synths, or Serum

• layer digital pads with organ tones

• create evolving atmospheres for science videos

It makes digital instruments feel natural — as if they were built into the organ or synth itself.

---

Typical Setup in Our Studio

1. MIDI from the Wersi or Synth

We route MIDI via USB or a MIDI interface into the studio computer.

2. Gig Performer Hosts the Instruments

Inside Gig Performer, each sound becomes a “rackspace”.
A rackspace can include:

• one VST instrument

• or a combination of instruments + effects

• or a layered performance patch

3. Physical Controls Assigned to Software Parameters

For example:

• Drawbar-style controls → filter cutoff / resonance

• Foot pedal → expression / dynamics

• Buttons on the synth → patch switches

• Aftertouch → vibrato depth

• Mod wheel → shimmer reverb or delay mix

This is where the performance feel comes alive.

4. Output Back to Audio Interface

The final sound runs through the studio interface into speakers or into the mix for videos.

---

Why This Is Useful for Philip M Russell Ltd Videos

1. Unlimited Sound Palette

Science videos often need subtle, atmospheric music.
VSTs offer textures that hardware alone can’t always produce.

2. Fast Composition

Need a gentle underscore for a chemistry demonstration?
A warm pad for a sailing montage?
A dramatic introduction for a R&D update?
Gig Performer lets you load and play instantly.

3. Consistent Playback

Unlike standalone DAWs, Gig Performer is designed for live reliability — perfect for filming sessions with no time to reboot between takes.

4. Organ + Synth + VST Hybrid

Blending these layers gives a unique sonic signature across your YouTube content.

---

Creative Possibilities

With the hybrid setup, you can:

• build evolving ambient beds

• turn spectra into music for your “Molecules Musical” videos

• recreate classical organ-like textures using sample libraries

• design sounds that follow experimental footage

• create percussive hits for science transitions

• use granular synthesizers for atmospheric sailing clips

It’s a playground for both teaching and creativity.

---

The Takeaway

Using Gig Performer to play VST instruments through your synths and organ creates a flexible, expressive, and professional music setup — without needing racks of hardware.

It brings the best of both worlds:
the performance feel of real instruments and the infinite palette of software.

Perfect for educational videos, science soundtracks, sailing content, and organ performances.
