Somewhere in your camera’s menu is a choice that most beginners skip past without a second thought — a choice that will affect every single image you make. How much latitude you have in post-processing, how your files behave under editing, how much of what you saw is preserved in what you share. That choice is RAW vs JPEG.
What Is a JPEG?
JPEG is a compressed image format. When you shoot JPEG, your camera captures the raw sensor data, applies your colour profile, sharpness, contrast, and noise reduction settings, compresses all of that into a finished file, and discards the original data. What you get is a ready-to-share image that looks great straight out of camera. The catch is that all of those decisions — colour rendering, tonal mapping, noise reduction — are made permanently at the moment of capture. Push a JPEG too far in editing and the limitations become visible: banding, clipped highlights that cannot be recovered, crushed shadows that turn to mush.
What Is a RAW File?
A RAW file is unprocessed sensor data. The camera records everything the sensor saw — all the tonal information, all the colour data, across the full dynamic range of the sensor — and stores it without making any permanent processing decisions. You open the file in editing software (Lightroom, Capture One, or Adobe Camera Raw) and make every decision yourself. RAW files are typically two to six times larger than JPEG equivalents. They look flat and unexciting when you first open them. But they hold extraordinary information — the ability to recover blown highlights, lift deep shadows, correct white balance after the fact, and fine-tune colour in ways that simply aren’t possible with a JPEG.
The Real-World Difference in Editing
Consider an outdoor portrait where the sky behind your subject is two stops brighter than their face. In JPEG, you expose for the face; the sky blows out and becomes a featureless white. In RAW, that sky’s information is still there — pull the Highlights slider in Lightroom and the clouds, the gradient, the colour all return. This isn’t a subtle difference. It’s the difference between a recoverable image and a ruined one. This recovery latitude is part of why the Landscape Photography 101 guide recommends RAW for all outdoor shooting. White balance is another area where RAW shines. Shoot under mixed lighting and a JPEG will try to average the two, usually poorly. With RAW, you adjust white balance freely in post, with zero quality loss, as many times as you like.
When JPEG Makes Sense
JPEG isn’t wrong — it’s a different tool for different needs. Sports and press photographers often shoot JPEG because they need to transmit images immediately, without a post-processing step. If you’re shooting in ideal light and your camera’s JPEG rendering is excellent, JPEG can be a perfectly valid choice. Many cameras also offer RAW + JPEG simultaneously — you get the convenience of a ready-to-share JPEG and the safety net of the RAW file if you need to revisit the image later. This is a reasonable middle ground for photographers still building their editing workflow.
💡 Pro Tip: Think of RAW as your digital negative. A film photographer would never discard negatives after getting one print made. RAW is yours to keep, revisit, and reinterpret as your skills grow and your editing tools improve. This is especially true for Black and White Photography, where channel mixing in the B&W Mix panel requires the full colour data that only RAW preserves.
The Recommendation for Most Photographers
If you have any intention of editing your images — adjusting exposure, refining colour, recovering difficult light — shoot RAW. The additional storage cost is trivial compared to the creative freedom it returns. Hard drives are cheap. The moment you missed because your highlights were unrecoverably blown cannot be reconstructed.
A Timeless Lens Perspective
Photographs are made twice — once when you press the shutter, and once when you sit down to edit. RAW honours both of those moments. It says: your judgment in the field matters, and your judgment at the screen matters too. It refuses to make permanent decisions on your behalf before you’ve had time to think. In a medium that is fundamentally about preserving the unrepeatable, RAW gives you the most complete version of what was there. That seems worth a few extra gigabytes.
