🔺 Ever felt like the exposure triangle needs three hands and a maths degree just to take one photo? It doesn't. In this episode Rick explains aperture, shutter speed and ISO in plain English — what each one actually does, how they work together, and which two settings he actually controls himself on every real shoot. If you're new to cameras, or you've never quite got your head around exposure, this one's for you.
What's Covered
●        🔺 What the exposure triangle actually is, and why photographers call it a triangle
●        🔘 Aperture — why the f-numbers feel backwards, and what depth of field really means
●        🎯 Shutter speed — freezing movement vs blurring it, and everything in between
●        💡 ISO — what it's actually doing to your photo (it isn't what you've been told)
●        ⚖️ How all three trade against each other in stops
●        😅 Why Rick doesn't juggle all three — the two settings he sets himself, and the one he leaves to the camera
●        📱 How the exposure triangle works inside your phone, even when it's hidden from you
●        🏢 Exactly what Rick does on a real architectural shoot

🎙️ Turn on image stabilisation, they said. It'll save your photos, they said. Nobody mentioned you'd need to turn it off again.
You've been told to always leave image stabilisation switched on. But put your camera on a tripod, and that same advice flips completely. In this episode, I explain exactly what image stabilisation does, how many extra stops it can buy you, and the moments where it can actually work against you. Whether you're shooting handheld, on a tripod, or panning a moving subject, this one's for you. 📸
🔧 What's In This Episode
●        What Image Stabilisation Actually Does — the one job it's built for, and nothing more.
●        How Many Extra Stops It Buys You — the genuinely useful benefit, explained properly.
●        Why It Fights You On A Tripod — and why the advice to switch it off makes total sense.
●        Two Different Places Stabilisation Can Live — in the lens, the body, or both.
●        The Panning Exception — the one time you move the camera on purpose and it still helps.
●        Video Needs More Help Than Stills — why your settings shouldn't be identical for both.
●        It Runs Your Battery Down Faster — the practical cost nobody mentions.

🎯 Your kit lens has something printed on the barrel. 18-55mm f/3.5-5.6. Confident. Specific. And absolutely meaningless — unless you know what any of it means. This episode fixes that.
In episode 239 of the Photography Explained Podcast, I explain every number and letter on your kit lens barrel. In plain English. Without the irrelevant detail. Including why the aperture numbering system is completely backwards — and why whoever invented it clearly did not consult anyone who was actually learning photography at the time.
In this episode:
●       📏 Tip 1: 18-55mm — the focal length range. What wide angle means. What the longer end does. Why the zoom ring is your best friend.
●       📷 Tip 2: f/3.5-5.6 — the aperture range. What aperture actually is. Why the numbers seem backwards (and they are). What maximum aperture means.
●       🔄 Tip 3: Why the aperture changes as you zoom — variable aperture explained, what a stop of light is, and why your kit lens is actually being very sensible.
●       🌟 Tip 4: What aperture does to your photos — depth of sharpness in practice, a birthday party in low light, and the two things you need to know about f/3.5 and f/5.6.
●       🔤 Tip 5: USM, STM, IS, and Roman numerals — what all those letters mean and why none of it is random.

There is a LOT of camera gear out there. Bodies, lenses, bags, tripods, filters, memory cards, drones, studio lights — and it can feel like you need to spend thousands of pounds before you've earned the right to call yourself a photographer. You don't. Not even close. In this episode I cut through all of it and tell you exactly what a beginner photographer actually needs, what can wait, and what you can safely ignore entirely. 📷
In this episode we cover:
●        📷 Tip 1 — The camera body: why it matters less than you think
●        🔭 Tip 2 — The lens: this is where your money should actually go
●        📐 Tip 3 — The tripod: do you actually need one, and when?
●        💾 Tip 4 — Memory cards: the unsung essential nobody talks about
●        🔋 Tip 5 — Batteries: no battery, no photos — it really is that simple
●        🔵 Tip 6 — Filters: mostly not for beginners (with one exception)
●        🔆 Tip 7 — Lens hoods: the most underrated bit of kit you own
●        🔵 Tip 8 — Lens caps: free, essential, and easily overlooked
●        🎒 Tip 9 — The camera bag: carry what you actually use, nothing else
●        🚫 Tip 10 — The gear you don't need yet: drones, studio lights, second bodies, super-zooms
