Why Bother With Raw?

A raw file isn't quite a photograph — it's the raw material for one. When you shoot JPEG, your camera makes a whole series of decisions on your behalf: how bright the scene should be, how warm or cool the colours look, how much contrast to apply. Raw files keep those decisions open, storing the full range of data your sensor captured so you can interpret the scene yourself, later, on a proper screen.

The practical benefit is headroom. Raw files typically hold a stop or two of recoverable detail in the highlights and a surprising amount in the shadows. That matters enormously in British conditions. A bright sky over a dark Lakeland fell, a stone cottage shot into low winter sun, a grey day in the Peak District where the contrast is so flat the image looks lifeless — all of these are far easier to rescue from a raw file than from a JPEG. You can also change white balance after the fact, which is a lifesaver when you're photographing under mixed light: daylight through a window and tungsten bulbs overhead, say, or the sodium glow of a city street at dusk.

Before You Touch A Slider

Get the boring bits right first, because editing is much more enjoyable when you know where your files are.

• Copy your images off the card to a folder named by date and place — 2025-03-14 Northumberland rather than DCIM_0042.
• Back them up. A second drive, kept somewhere else, is the difference between an inconvenience and a disaster.
• Don't delete raw files once you've exported a JPEG. Your editing software stores adjustments as a set of instructions, not baked into the file, so you can revisit an image in five years and reinterpret it completely.

And resist the urge to edit everything. Pick the three or four strongest frames from a shoot and give them proper attention.

The Five Sliders That Do Most Of The Work

Most editors put the same essential controls in the same order. Learn these and you'll handle eighty per cent of your images without going any further.

• Exposure — the overall brightness. Set this first, judging the midtones: grass, stone, skin, grey tarmac.
• Highlights — pull this down to bring back detail in bright skies and white water. In a raw file you'll often find cloud texture you thought was lost.
• Shadows — lift this to open up dark foregrounds and woodland. Go gently; heavy lifting reveals noise and flattens the image.
• Whites and Blacks — these set the endpoints. Nudge Whites up until the brightest areas just start to clip, then Blacks down until the darkest parts have real depth. If your software supports it, hold the Alt or Option key while dragging and watch the clipping warnings appear.
• Contrast — a blunt instrument, but useful for a quick sense of direction before you refine things elsewhere.

White Balance And Colour

Temperature and tint control the colour cast. If you shot a grey card or something genuinely neutral, use the eyedropper on it and the rest of the image falls into line. Otherwise trust your eye, and don't be afraid to work creatively: a little warmth in a golden-hour coastal shot at Whitby feels right, whilst a cooler cast suits a misty morning in the Chilterns.

For saturation, prefer vibrance over saturation — it protects skin tones and already-saturated colours. A word of warning about British landscapes: our greens are naturally rich, and a heavy hand here turns grass into something radioactive. Less is almost always more.

Curves, Masks And Local Adjustments

Once the global adjustments look sensible, a gentle S-curve in the tone curve panel adds contrast and depth without the muddiness that the basic slider can introduce. It's the single most useful tool for giving an image a bit of life.

Then start working locally. A graduated filter is perfect for darkening a blown-out sky or brightening a dull foreground; a radial filter draws the eye to your subject. Modern masking tools let you select the sky, the subject, or a specific colour range, which means you can brighten a backlit face without touching the rest of the frame. Keep an eye out for halos along horizons and rooflines — a sure sign you've pushed a mask too hard.

Finishing: Sharpening, Noise And Export

Leave sharpening and noise reduction until last, and always judge them at 100% zoom. Your image will look crisp at fit-to-screen and still be soft where it counts.

Sharpen with the subject in mind — a landscape tolerates more than a portrait. For noise, a light touch of luminance reduction cleans up the grain you'll get shooting high ISO at a winter dusk, whilst colour noise reduction tidies the speckled patches in shadows. Apply lens corrections if your software offers them; they'll fix the slight distortion and vignetting most lenses show wide open.

Export as an sRGB JPEG for sharing and for most print labs, resizing to around 2000 pixels on the long edge for the web. If you plan to do more work later, save a 16-bit TIFF. Finally, look at the exported file on a phone as well as your monitor — that's how most people will actually see it, and it's a quick way to catch an edit that's gone too far.
