Let's talk about flash! I know what you might be thinking: "flash makes my photos look rubbish" or "I'm a natural light photographer". I get it, I really do. But here's the thing: flash on film cameras is actually brilliant when you know how to use it properly, and there are loads of situations where it's not just helpful, it's a must-have.

Why Your Film Camera Needs Flash

Film cameras don't have the luxury of cranking the ISO up to 25,600 for low-light shots like modern digital cameras. When you load a roll of ISO 400 film, that's what you've got to work with until you finish the roll. Flash gives you consistent, reliable light that you can actually control. 

When Do You Need to Use Flash?

Indoor photography

This is the big one. Indoor lighting is almost always a no-go for film photography (without a tripod, anyway). Your living room might feel well-lit to your eyes, but your film will struggle. Even with ISO 400 or 800 film, you're looking at shutter speeds that are way too slow to shoot handheld without getting blurry photos.

Most film cameras with focal plane shutters sync with flash at speeds between 1/60 and 1/250 of a second. A Canon AE-1 syncs at 1/60, while a Nikon FM2n syncs at 1/250. This is loads faster than you'd be able to shoot indoors without flash, which means you can get sharp photos every time.

Low-light and night photography

Flash freezes motion brilliantly because the flash duration itself is incredibly fast. This means you can capture sharp images of people at parties, events or any situation where there's movement in low light.

Think about parties, gigs, pub gatherings or restaurants, all situations where you want to capture candid moments but the lighting isn't bright enough. 

Without flash, you'd need shutter speeds like 1/15 or even slower, which means any movement creates blur when shooting handheld. But with flash, the actual burst of light lasts only 1/1000 of a second or faster, completely freezing the action even if your shutter is set to 1/60 or 1/250. The flash does the work of stopping motion, not your shutter speed.

Portrait photography

Flash gives you consistent, controllable light for professional-looking results. Portrait photographers bounce it off ceilings or walls to create soft, flattering light that makes subjects look their best.

The difference between direct flash (pointing straight at someone's face) and bounced flash is night and day. Direct flash is harsh and unflattering, but bouncing the flash off a white ceiling or wall turns that surface into a massive, soft light source. It's the difference between your subject looking like a deer in the headlights and looking naturally lit and three-dimensional. We'll cover bouncing techniques properly in later articles, but trust me, it's a game-changer for portraits.

Fill flash in bright daylight

Now this might sound mad — using flash when it's sunny — but hear me out. Harsh sunshine creates ugly dark shadows, especially under people's eyes, noses and chins. These shadows can be so dark that your film just captures them as black blobs.

Fill flash is when you use a bit of flash to "fill in" these shadows, not to overpower the sunlight. It's subtle, flattering and it makes portraits look miles better. This works brilliantly when your subject is backlit too, like when someone is standing in front of a window, or has the sun behind them and they appear as a silhouette.

Controlling light and creating mood

Flash isn't just about adding light, it's about creative control. You can balance exposure between your subject and the background, create dramatic lighting, or add light exactly where you want it. Getting the lighting right in-camera is crucial with film.

For example, you might want to photograph someone in a dimly-lit room but keep that moody ambient lighting in the background. Flash lets you expose for the dark background while lighting your subject properly. Or perhaps you want dramatic side-lighting for a creative portrait. Flash gives you options that just aren't possible with available light alone.

What about "natural light only" photography?

I completely get the appeal of natural light. It's beautiful, it's free and it doesn't require any extra gear. But limiting yourself to *only* natural light on film is like... well, it's like only driving in the daytime because headlights are "cheating."

Natural light is lovely when it's available and when it's doing just what you want. But it's not always available, and it doesn't always cooperate. Film has a limited dynamic range compared to modern high-end digital sensors, which means it's less forgiving when the light isn't ideal. Flash isn't about replacing natural light — it's about supplementing it, controlling it and having options when natural light isn't enough.

Whether you're shooting indoors, outdoors in low or harsh light, at parties or live events, or you just want more creative control over your lighting, flash opens up massive possibilities that just aren't available with natural light alone.

The key is learning to use it properly, which we'll cover in the rest of this series. When used well, flash doesn't have to make your photos look "flashy". It can make them look more professional, well-exposed and properly lit.

In the next post, we'll dive into the different types of flash available for film cameras, from built-in flashes to powerful external units. Understanding your options will completely change how you think about flash photography, trust me!
