A Beginner's Guide to Shooting in Raw Format

What Raw Actually Is — and Why It Matters

Every time you press the shutter, your camera has a decision to make. It can hand you a finished JPEG — processed, sharpened, compressed and ready to share — or it can give you a raw file, which is essentially everything the sensor saw, with none of the decisions made for you.

A JPEG is a bit like a print from a lab: pleasant, convenient, but final. A raw file is the negative. The camera records 12 or 14 bits of data per colour channel rather than the 8 bits in a JPEG, which means far more tones and a huge amount of headroom when you start editing. Nothing is baked in. White balance, contrast, colour, sharpening and noise reduction are all yours to set later, on a proper screen, with time to think.

In practice, that flexibility shows up in a few ways:

• White balance can be changed as freely as a slider after the fact, so a wrongly warmed or cooled shot isn't ruined.
• Highlights that look blown often hold recoverable detail, and deep shadows can be lifted without the image falling apart.
• Colour responds far more gracefully to adjustment — subtle gradations in a UK sky stay smooth instead of banding.

The Honest Trade-Offs

Raw isn't free. Before you switch, know what you're taking on.

• File size. A 24-megapixel camera might produce 25–35MB raw files against 6–8MB JPEGs. Buy bigger cards and plan your storage.
• Buffer depth. Continuous bursts fill up faster, which matters if you photograph wildlife or sport.
• Processing time. Every image needs at least a little attention. Fifty shots from a weekend walk is fine; two thousand from a wedding is a different job.
• Sharing friction. Some cameras won't transfer raw files over Wi-Fi to a phone. Shooting raw plus JPEG solves this neatly — keep the JPEGs for quick sharing and the raw files for anything you love.

Setting Your Camera Up Correctly

Spend ten minutes in the menu before your next outing.

• Set image quality to raw or raw + JPEG fine. On most cameras this sits in the first shooting menu.
• Format your card in the camera, not on a computer, and carry a spare. If your camera has two slots, use the second as an overflow or backup.
• Turn on the highlight warning (often called blinkies) and learn to read the histogram. These two tools will teach you more about exposure than any article.
• Set a consistent white balance — Daylight or Auto, but the same one all day. It makes batch editing far quicker because your adjustments transfer sensibly between frames.
• Don't worry about the colour space setting. It only affects JPEGs, so it makes no difference to a raw file.

Getting Exposure Right in the Field

Raw gives you latitude, not magic. A badly overexposed file still has blown highlights that no software can invent, so the golden rule is simple: protect the highlights. A slightly dark raw file with detail intact is easy to rescue; a white, featureless sky is not.

Check the histogram after a test shot and adjust. If the right-hand edge is climbing a wall, dial in a little negative exposure compensation and shoot again. Bracket if you're unsure — three frames a stop apart costs you nothing but card space.

Here's the good news for British photographers: our famously soft, grey, flat light is ideal for raw. Low-contrast scenes are exactly where all that extra tonal data pays off, because you can add contrast and shape back in later without introducing noise. Coastal mist, woodland in autumn, city streets under cloud — all superb raw territory.

And resist judging anything on the camera's rear screen. It flatters, lies and is unwatchable in sunlight.

Your First Editing Session

Open your first raw file and you may be disappointed. It looks flat, dull and slightly lifeless. That's completely normal — you're seeing unprocessed data, not a mistake.

Work in a sensible order:

• Lens corrections first — distortion, vignetting, chromatic aberration.
• Exposure and contrast, then highlights and shadows to bring the tonal range under control.
• White balance to taste, followed by a gentle curve or clarity boost.
• Colour last — vibrance rather than saturation, which protects skin tones.
• Noise reduction and sharpening at the very end, viewing at 100 per cent.

When you're happy, export as a JPEG at full size for printing, or around 2048 pixels on the long edge for the web, in sRGB. If you're passing the file to another program, export a 16-bit TIFF instead.

Building a Workflow That Sticks

Raw only becomes effortless when the routine is automatic. Import into dated folders — year, then month — and back up to two places, ideally with one copy off-site. Cull before you edit, using star ratings so you're only spending time on keepers. Save presets for the looks you return to often, and apply them across a whole shoot, then fine-tune individually.

Finally, resist the urge to over-edit. Compare your finished image against the original now and then, and keep the raw files forever — storage is cheap, and your editing skills will only improve. The negatives you shot carelessly last year may well become this year's favourites.
