Editing 360° Camera Footage as a “Normal” View

 


Editing 360° Camera Footage as a “Normal” View

Capturing shots you’d never get with a conventional camera

One of the quiet superpowers of a 360° camera isn’t the immersive headset view or the novelty of spinning the image around with your finger.

It’s what happens after you’ve finished filming.

When you edit 360° footage as a normal flat video, you’re not just trimming clips – you’re choosing the camera angle after the event. And that changes how, where, and even why you film.


🎥 One camera, every angle

A traditional camera forces you to make decisions up front:

  • Where do I point it?

  • What if something interesting happens just out of frame?

  • Should I pan… or zoom… or move the tripod?

With a 360° camera, the answer is simple:
point it everywhere.

Once recorded, you can reframe the footage as if you were operating a virtual camera inside the scene – panning, tilting, zooming, and even tracking movement that you didn’t anticipate at the time.

That means:

  • No missed reactions

  • No “I wish I’d pointed it slightly left”

  • No need for a second camera just in case


🎯 Capturing the moments you didn’t plan for

Some of the best moments are unplanned:

  • A student’s expression when an experiment finally clicks

  • A boat drifting into perfect alignment on the river

  • A subject entering the frame unexpectedly

With a standard camera, those moments are often lost forever.

With 360° footage, they’re still there – quietly waiting for you to discover them on the edit timeline.


✂️ Editing 360° footage like a normal video

Modern editing software lets you treat 360° footage as raw material rather than a final format.

You can:

  • Reframe into standard 16:9 or vertical video

  • Add smooth pans and camera moves that look deliberate

  • Create multiple clips from a single take, each with a different viewpoint

  • Output content for YouTube, TikTok, lessons, or blogs from the same recording

In practice, it’s a bit like filming with a locked-off wide shot…
…and then deciding later where the close-ups should have been.


🧠 Why this matters for education and explanation

In teaching and demonstration work, this is gold.

You can:

  • Follow hands during a practical without reshooting

  • Cut between speaker and apparatus from one camera

  • Maintain eye contact after filming by reframing correctly

  • Reduce cognitive overload by guiding the viewer’s attention in post

It turns filming from a high-pressure performance into a capture-first, decide-later process.


🚀 Less stress, more usable footage

Ironically, filming everything often results in simpler production:

  • Fewer retakes

  • Less camera choreography

  • Smaller crew (sometimes just you)

  • More freedom to focus on teaching, sailing, or demonstrating

The camera becomes a safety net rather than a constraint.


Final thought

360° cameras aren’t just about immersive viewing.

Used this way, they’re time machines – letting you go back and choose the shot you didn’t know you needed.

And once you’ve worked like that, it’s surprisingly hard to go back.

What Makes a Duet Special?


 What Makes a Duet Special?

Musical duets can be surprisingly powerful tools when it comes to creating backing tracks for videos and a whole range of other creative uses.

Here’s how duets quietly punch above their weight.


What Makes a Duet Special?

At its heart, a duet is about conversation rather than clutter.

With only two musical lines:

  • Each part is clearly audible

  • Roles are naturally defined (melody vs support, call vs response)

  • The texture stays light, focused, and flexible

That simplicity is exactly why duets work so well in media.

Duets as Backing Tracks for Video

1. Clear Structure for Narration

For educational, documentary, or explainer videos, duet-based backing tracks are ideal:

  • One instrument carries a gentle harmonic bed

  • The second adds light melodic interest

  • Neither overwhelms spoken voice

This is perfect for:

  • Science and education videos

  • Sailing explainers

  • Tutorials and demonstrations

(Exactly the kind of content you’re producing for Philip M Russell Ltd.)


2. Built-In Dynamics

Duets naturally allow contrast:

  • One part can drop out under speech

  • The other can re-enter for emphasis

  • Simple automation feels musical, not mechanical

That makes them easier to edit than dense, multi-track arrangements.


3. Emotional Balance

A single instrument can feel exposed.
A full ensemble can feel overproduced.

A duet sits neatly in the middle:

  • Warm but uncluttered

  • Human rather than cinematic

  • Engaging without demanding attention


Other Practical Uses of Duets

🎬 Titles, Intros & Outros

Duets are excellent for:

  • Video intros and outros

  • Chapter breaks

  • Segment transitions

The interaction between parts creates a sense of movement and purpose, even in short cues.


🎓 Teaching & Demonstration

Duets are fantastic educational tools:

  • Demonstrate harmony and counter-melody

  • Show balance and listening skills

  • Easy to strip back and analyse

They also translate brilliantly into visual teaching, where students can see which line is doing what.


🎹 Adaptive & Modular Music

Because the parts are independent:

  • You can mute one line for quieter moments

  • Swap instrumentation easily

  • Re-use the same piece across multiple videos

That makes duets incredibly efficient for content creators building a reusable music library.


Beyond “Just Two People Playing”

In modern production, a duet doesn’t even require two performers:

  • One person recording layered parts

  • Virtual instruments paired with live playing

  • Organ + synth, piano + strings, melody + texture

The duet becomes a design philosophy, not just a performance format.


✅ The Bottom Line

Musical duets:

  • ✅ Make excellent backing tracks

  • ✅ Sit beautifully under narration

  • ✅ Are flexible, editable, and reusable

  • ✅ Add humanity without clutter

They’re not just fun to play—they’re practical, elegant tools for modern video and media production.

Filming Small Explosions with a Camera

 


Filming Small Explosions with a Camera

Protecting Your Kit While Capturing the Science

Filming small explosions — flash reactions, gun cotton, hydrogen balloons, pressure releases — can produce stunning visuals that genuinely help students see chemistry and physics in action.

But while we obsess over human safety (rightly), it’s easy to forget that cameras, lenses, microphones, and lighting rigs are also sitting right in the danger zone.

And camera repairs are not covered by the CLEAPSS handbook.

What Counts as a “Small Explosion”?

In an educational context, we’re usually talking about:

  • Flash reactions (e.g. gun cotton, lycopodium powder)

  • Rapid gas expansion

  • Small combustion demonstrations

  • Contained pressure releases

Short duration. Low mass. High visual impact.

Still more than enough to:

  • Pepper a lens with debris

  • Crack a filter

  • Cook a sensor with heat or IR

  • Kill an exposed microphone


🔒 Camera Safety: Lessons Learned the Hard Way

1. Distance Is Your Cheapest Insurance

Even doubling the distance massively reduces:

  • Heat exposure

  • Overpressure

  • Debris impact

Use:

  • Longer focal lengths

  • Cropped sensors

  • Post-production framing

If it looks “too far away” on set, it’s usually perfect in edit.


2. Sacrificial Filters Are Not Optional

A £15 UV or clear filter:

  • Takes the hit from debris

  • Protects the front element

  • Is far cheaper than replacing glass

Consider stacking:

  • Clear filter (impact)

  • IR-cut filter (heat & sensor protection)

If it shatters, you’ve won.


3. Shield the Camera, Not the Experiment

Perspex, polycarbonate, or even thick acrylic sheet:

  • Stops fragments

  • Survives heat

  • Lets you keep a clear view

Important:
➡️ Angle the shield, don’t mount it flat. Reflections and shockwaves behave badly off flat surfaces.


4. Heat and Infrared Are Silent Killers

Explosions don’t just throw bits — they emit:

  • Intense IR

  • Localised thermal spikes

Solutions:

  • IR-cut filters

  • Avoid wide-open apertures

  • Keep sensors cool between takes

This matters especially with mirrorless cameras.


5. Remote Everything

If the camera can be triggered remotely, do it:

  • Remote record

  • Wireless monitoring

  • Pre-focused manual setups

Bonus: it also makes students take safety more seriously when nobody is near the kit.


6. Audio Is Expendable

Mics are fragile.

  • Use cheap lavs or boundary mics

  • Keep primary audio well back

  • Expect to replace windshields

Explosions are visual teaching moments — audio is secondary.


🎓 Why This Matters Educationally

High-speed or slow-motion explosion footage:

  • Turns abstract theory into observable reality

  • Improves recall and engagement

  • Lets students replay what the human eye misses

But modelling professional safety practice is part of the lesson.

Students don’t just learn chemistry or physics — they learn how scientists work responsibly.


🧪 Final Thought

If your camera setup feels slightly over-protected, you’ve probably got it right.

If it feels excitingly close… it’s already too close.

Is it worth keeping an old but good digital camera, or is now a good time to upgrade?


Is it worth keeping an old but good digital camera, or is now a good time to upgrade?

 This is a really good (and very common) question — and it’s one I hear a lot from people who actually use their cameras rather than just read spec sheets. So let us take my old camera and ask the questions.

The short answer is: my Canon 7D is not obsolete — but it is showing its age in specific, very real ways. Whether you keep it or jump ship depends less on the camera and more on what you’re asking it to do now.


What the Canon 7D still does brilliantly

Let’s give it some respect first.

The 7D was built like a tank and designed for serious photography. Even now it still offers:

For:

…it’s still perfectly capable. For blogs, websites, and even print up to sensible sizes, the image quality itself is rarely the limiting factor.


Where the 7D is now clearly behind

This is where the frustration usually creeps in.

1. Low-light performance

Newer sensors are simply better:

If you’re shooting indoors, at dusk, or in winter light — you’ll feel this.

2. Autofocus intelligence

Modern cameras bring:

Once you’ve used these, going back can feel like stepping into the past.

3. Video (this is the big one)

By modern standards, the 7D’s video is:

  • Limited resolution

  • No modern codecs

  • No in-body stabilisation

  • No reliable continuous AF

If video is now central to your workflow (YouTube, reels, teaching clips), this is where the camera really shows its age.

4. Mirrorless ecosystem momentum

The industry has moved:

DSLR development is effectively frozen.


The real question: replace everything or transition slowly?

This is where people often think in extremes — and don’t need to.

❌ “Sell everything and start again”

  • Painfully expensive

  • Existing lenses lose value

  • Steep learning curve

  • Often unnecessary unless you need cutting-edge features

✅ A smarter middle ground

Many photographers are now doing this:

  • Keep the 7D for:

    • Still photography

    • Backup body

    • Teaching / experiments

    • Rough conditions where you don’t want your newest kit at risk

  • Add one modern body (often mirrorless)

  • Use lens adapters so your EF glass still works

  • Upgrade lenses only when there’s a clear benefit

This spreads cost, keeps familiarity, and avoids throwing away perfectly good tools.


A useful way to decide (quick checklist)

Ask yourself honestly:

  • Am I missing shots because of autofocus limitations?

  • Is low-light noise now affecting real outputs, not just pixel-peeping?

  • Is video now as important as photography?

  • Do I want lighter kit and better stabilisation?

  • Is this a business expense or a hobby cost?

If you answered “yes” to several of those → a partial upgrade makes sense.
If mostly “not really” → the 7D still earns its keep.


The uncomfortable truth (but also the freeing one)

Most people don’t outgrow their camera’s image quality — they outgrow:

  • Autofocus convenience

  • Video expectations

  • Workflow speed

The Canon 7D didn’t suddenly become bad.
The world around it moved on.


Bottom line

  • Don’t panic-upgrade.

  • Don’t sell good glass in a rush.

  • Treat the 7D as a reliable workhorse, not dead weight.

  • Upgrade when a new body genuinely changes what you can create, not just what the spec sheet says.

Sailwave → Spreadsheet: using Python as the “glue” between two programmes

 


Sailwave → Spreadsheet: using Python as the “glue” between two programmes

Sailwave is brilliant at race administration. Spreadsheets are brilliant at analysis. The only annoying bit is the squishy middle: getting consistent, tidy race data out of Sailwave and into a format that your handicap calculations can trust.

That’s where Python earns its tea and biscuits.

Instead of manually copying results (and accidentally turning “1.0” into “10” or “RET” into “0”), a short Python script can:

  • Grab Sailwave results (CSV export, HTML export, or a saved results file)

  • Standardise boat names / helm names (goodbye “Phil R”, “P Russell”, and “Philip Russell” as three separate people)

  • Normalise codes like DNC/DNF/RET/DSQ

  • Output a clean results table ready for your “Personal Handicap” spreadsheet

  • Optionally append straight into an .xlsx file so the whole thing becomes one seamless workflow

In other words: Sailwave stays your race tool, Excel stays your analysis tool, and Python quietly acts as the bridge that stops humans doing repetitive, error-prone admin.


The practical workflow (simple + robust)

Step 1 — Export from Sailwave

Most clubs can export race results as CSV or HTML. CSV is easiest to automate.

Your goal is a file that contains (at minimum):

  • Helm / Boat / Class (optional)

  • Race number / Date

  • Corrected time or points (depending on your approach)

  • Finish code (DNC/DNF/RET/DSQ) if present

Step 2 — Parse + tidy in Python

Step 3 — Feed the spreadsheet

Now your handicap spreadsheet can reliably:

  • filter out DNC/DNF/RET etc

  • weight recent races more heavily

  • compare “expected vs actual” using PY/PN

  • compute a rolling personal adjustment

If you want the script to write directly into an Excel sheet (instead of outputting a CSV), tell me what your workbook + sheet are called and I’ll give you a clean openpyxl version that appends data to a table without breaking formatting.


Why this matters for Personal Handicaps

Personal handicaps live or die on data quality.

A single inconsistent helm name, a missing DNF marker, or one race imported twice can skew the numbers enough to start arguments in the dinghy park (and nobody needs that before tea).

Python helps because it’s:

  • repeatable (same rules every time)

  • auditable (you can see exactly how values are treated)

  • extendable (add name matching, boat changes, discard rules, weighting, outlier rejection…)

And best of all: once it works, you press go and it just… does it.

DIY Becomes Science: How Fillers Go from Powder + Water to Rock-Hard (and Sandable)

 


DIY Becomes Science: How Fillers Go from Powder + Water to Rock-Hard (and Sandable)

At first glance, wall filler looks like magic.

You add water to a fine powder, stir it into a paste, slap it into a hole…
…and somehow it turns into a hard, sandable surface that bonds to the wall and stays there for years.

But there’s no magic involved at all.
It’s materials science, chemistry, and physics quietly doing their thing.

Let’s take a closer look at what’s actually happening.


Step 1: What’s in the Powder?

Most common DIY fillers are based on calcium sulfate hemihydrate — closely related to plaster of Paris.

The dry powder contains:

  • Fine mineral particles

  • Additives to control setting time

  • Fillers to reduce shrinkage

  • Binders to improve adhesion

At this stage, nothing has “set”. The material is chemically primed, waiting for water.


Step 2: Adding Water – More Than Just Mixing

When you add water, two things happen at once:

🔹 Physical process

The water wets the powder, allowing it to flow into cracks and holes. This is why the water-to-powder ratio matters so much:

  • Too much water → weak, crumbly filler

  • Too little water → poor workability and bonding

🔹 Chemical reaction (the important bit)

The powder hydrates. The calcium sulfate reacts with water to form a new crystalline structure.

This is not drying.
This is a chemical change.


Step 3: Crystal Growth = Strength

As the filler reacts:

  • Needle-like crystals grow and interlock

  • The structure expands microscopically

  • Voids are filled from the inside

This crystal network is what gives filler:

  • Hardness

  • Strength

  • Good adhesion to masonry, plaster, and board

It’s also why filler can feel warm as it sets — the reaction is exothermic.


Step 4: Setting vs Drying (A Common Myth)

Filler:

  • Sets by chemical reaction

  • Dries by water evaporation

It can be:

  • Chemically set but still damp

  • Hard to the touch but not ready to paint

That’s why sanding too early clogs paper, and painting too soon causes peeling or patchiness.


Step 5: Why It Sands So Nicely

Once fully set and dried:

  • The crystal structure is rigid but brittle

  • Abrasive paper fractures it cleanly

  • You get a smooth feathered edge rather than tearing

That balance — strong but sandable — is engineered deliberately.

Too strong and it behaves like concrete.
Too weak and it crumbles.


Why This Matters for DIY (and Teaching)

Understanding the science explains:

  • Why mix ratios matter

  • Why timing matters

  • Why rushing ruins finishes

It also turns a “boring DIY job” into a perfect everyday science demonstration:

  • Chemical reactions

  • Phase changes

  • Structure–property relationships

Your wall is basically a lab bench.


The takeaway

Next time you mix filler, you’re not just fixing a hole —
you’re triggering a controlled chemical reaction designed to grow crystals exactly where you want them.

DIY isn’t guesswork.
It’s applied science with a sanding block.

When Note-Taking Doesn’t Work – And What to Do Instead


 When Note-Taking Doesn’t Work – And What to Do Instead

Note-taking is often described as an essential academic skill, one that students are expected to master early and then carry all the way through GCSEs, A-Levels, university, and beyond.

But the reality in classrooms and tuition rooms is rather different.

Some students simply don’t learn effectively by writing notes. They copy without understanding, write too slowly, miss key explanations, or end up with pages of text that never get revisited. For these learners, “take better notes” isn’t helpful advice — it’s a barrier.

In this article, we look at:

  • Why traditional note-taking doesn’t work for every student

  • Common problems with copying, speed, and cognitive overload

  • The difference between recording information and learning it

Most importantly, we explore effective alternatives:

  • Structured worksheets and guided notes

  • Diagrams, flowcharts, and concept maps

  • Audio explanations and annotated examples

  • Exam-focused summaries and model answers

  • Teacher-created resources that free students to think, not scribble

Somestimes even this doesn't work and completely radical methods need to be used.

Good note-taking can be taught — but it isn’t the only route to success.
The real goal is understanding, recall, and application, not beautifully written pages that are never used again.

Why Traditional Note-Taking Doesn’t Work for Every Student

Traditional note-taking assumes that all students can:

  • Listen and understand in real time

  • Identify what is important

  • Summarise ideas accurately

  • Write quickly enough to keep up

For some learners, this happens naturally.
For many others, it doesn’t — and the problem is rarely effort or motivation.

Students vary enormously in:

  • Processing speed

  • Working memory capacity

  • Language fluency

  • Motor skills and handwriting stamina

When note-taking exceeds a student’s cognitive capacity, it stops supporting learning and starts competing with it.


Common Problems: Copying, Speed, and Cognitive Overload

1. Copying Becomes the Goal

In many classrooms, note-taking quietly turns into copying.

Students focus on:

  • Writing down everything on the board

  • Transcribing slides word-for-word

  • Matching the teacher’s pace

The unintended message becomes:

If it’s written down, it must be important.

This leads to:

  • Notes with no hierarchy or emphasis

  • Definitions copied without understanding

  • Diagrams reproduced without explanation

The student may feel productive, but very little thinking is happening.


2. Speed Mismatch: Teaching vs Writing

Teachers naturally speak faster than most students can write.

This creates a constant tension:

  • Keep up with the writing

  • Or stop writing and listen

Many students attempt to do both — and succeed at neither.

Common outcomes include:

  • Missing key explanations while writing

  • Skipping steps in worked examples

  • Writing fragments that make no sense later

For slower writers or students with weaker handwriting fluency, the lesson becomes a race rather than a learning experience.


3. Cognitive Overload in Real Time

Working memory is limited.
When students are asked to:

  • Listen

  • Understand

  • Decide what matters

  • Convert it into written form

…they can exceed that limit very quickly.

When cognitive overload occurs:

  • Understanding drops sharply

  • Errors creep into notes

  • Misconceptions go unchallenged

This is especially damaging in cumulative subjects like Maths, Physics, and Chemistry, where missing one idea undermines everything that follows.


Recording Information vs Learning It

One of the most persistent myths in education is that writing something down means it has been learned.

In reality, these are two very different processes.

Recording Information

Recording is:

  • Passive

  • Mechanical

  • Focused on capture

A student can record information accurately without understanding any of it.

This often leads to:

  • False confidence

  • Overreliance on notes

  • Poor transfer to exam questions


Learning Information

Learning requires:

  • Processing meaning

  • Making connections

  • Identifying cause and effect

  • Applying ideas in new contexts

This can happen:

  • With minimal writing

  • Through discussion

  • Via diagrams or worked examples

  • Through questioning and explanation

A student who listens carefully, asks questions, and later produces a short, accurate summary may learn far more than one who writes continuously.


Why This Matters for GCSE and A-Level Students

At exam level, success depends on:

  • Understanding command words

  • Applying knowledge, not recalling paragraphs

  • Using concepts flexibly

Students who confuse note-taking with learning often discover too late that:

  • They recognise the topic

  • They remember writing it down

  • But they cannot use it in an exam

This is not a failure of intelligence — it is a mismatch between method and learner.


The Key Takeaway

Note-taking is a tool, not a test of ability.

If it:

  • Distracts from understanding

  • Overloads working memory

  • Produces notes that aren’t used

…then it needs adapting or replacing.

The goal is not full pages.
The goal is thinking, understanding, and recall when it matters.

When traditional note-taking fails, the first step is usually to reduce the writing load while increasing thinking time. Many students make immediate progress with structured alternatives.

Structured Worksheets and Guided Notes

Instead of starting with a blank page, students are given:

  • Clear headings

  • Key questions

  • Spaces for diagrams or worked examples

This shifts the task from deciding what to write to understanding what is being taught.
Cognitive load drops, attention improves, and misconceptions are more likely to be spotted.


Diagrams, Flowcharts, and Concept Maps

For many learners, especially in science and maths:

  • Visual structure beats linear text

  • Relationships matter more than wording

Flowcharts show process.
Concept maps show connections.
Diagrams reduce language load while preserving meaning.

For some students, a single well-constructed diagram replaces two pages of notes.


Audio Explanations and Annotated Examples

Some learners process information far better through:

  • Listening

  • Replaying explanations

  • Hearing ideas explained in multiple ways

Annotated worked examples — where each step is explained verbally or visually — allow students to focus on why something happens, not just what happens.


Exam-Focused Summaries and Model Answers

At GCSE and A-Level, the end goal is assessment.

Exam-focused resources prioritise:

  • Key definitions

  • Typical questions

  • Command words

  • Common mistakes

Students stop drowning in content and start recognising how knowledge is used, which is what exams actually reward.


Teacher-Created Resources That Free Students to Think

High-quality teacher resources:

  • Remove unnecessary copying

  • Control pacing

  • Direct attention to the key ideas

This allows students to spend lesson time thinking, questioning, and applying — rather than scribbling.

For many learners, these approaches are enough.

But not for all.


When Even These Don’t Work: Radical Learning Approaches

Some students still struggle — not because they are unwilling or incapable, but because any form of simultaneous listening, processing, and recording overwhelms them.

At this point, it’s time to stop tweaking traditional methods and change the model entirely.

1. Video Recording Instead of Note-Taking

Instead of writing notes, the student:

  • Records the explanation (video or audio)

  • Focuses fully on listening and understanding

  • Revisits the explanation later

This separates learning time from recording time, reducing cognitive overload dramatically.

The student can then:

  • Pause

  • Rewind

  • Replay difficult sections

This is often transformational for slower processors.


2. AI-Assisted Extraction of Key Information

A radical but increasingly practical approach:

  1. The lesson or explanation is recorded

  2. AI tools transcribe the audio

  3. Key points are extracted, summarised, or structured afterwards

The student ends up with:

  • Clear notes

  • Accurate terminology

  • Reduced cognitive strain

Crucially, the student’s mental energy is spent on understanding, not transcription.


3. Verbal Learning First, Written Output Later

Some students learn best by:

  • Talking

  • Explaining ideas aloud

  • Teaching someone else

They may:

  • Record verbal summaries

  • Explain a concept to a teacher, parent, or even an empty room

  • Answer questions orally

Only after understanding is secure do they produce short, focused written summaries — often with far greater clarity than traditional notes.


4. “No Notes During Teaching” Lessons

This feels radical, but it can be powerful.

Rules:

  • No writing during explanation

  • Full attention on listening and questioning

  • Notes created after the lesson from memory, discussion, or prompts

This forces engagement and reveals what has actually been understood — rather than what has been copied.


5. Output-First Learning

Instead of notes first, students begin with:

  • Exam questions

  • Problems

  • Tasks

They discover what they don’t know, then access targeted explanations or resources to fill the gaps.

Learning becomes purposeful, not passive.


Rethinking What “Proper Learning” Looks Like

Many students (and parents) worry when learning doesn’t look traditional:

  • “There aren’t enough notes”

  • “The book doesn’t look full”

  • “It doesn’t look like school”

But learning is not measured by:

  • Page count

  • Neat handwriting

  • Quantity of text

It’s measured by:

  • Understanding

  • Recall

  • Transfer to new problems

  • Performance under exam conditions

If a student learns best by listening, recording, replaying, explaining, or using AI-supported summaries, then that method is not a shortcut — it’s an appropriate adaptation.


The Bottom Line

When note-taking fails:

  • Adapt it

  • Replace it

  • Or remove it entirely

The goal is not compliance with tradition.
The goal is learning that works.
