RAW vs JPEG Photography Explained: What Your Photographer Is Shooting

What Is a RAW File?

A RAW file is the unprocessed data captured directly by the camera sensor. When a camera takes a photograph in RAW format, it records all the light information the sensor measured — exposure, colour, shadow and highlight detail — without applying any in-camera processing or compression. The file contains the full dynamic range of information captured at the moment of shooting.

RAW files cannot be viewed by most standard image viewers without specialist software (like Adobe Lightroom, Capture One, or the camera manufacturer's own viewer) because they require a development process to convert from raw sensor data into a viewable image. This development process is where a photographer's editing decisions are applied.

What Is a JPEG?

A JPEG is a processed and compressed image file. When a camera shoots JPEG, it takes the raw sensor data and immediately applies the camera's built-in processing algorithms — sharpening, contrast curves, colour profiles — and then compresses the result. This happens automatically in-camera and the raw data is discarded. The JPEG is the camera's interpretation of the scene, with limited latitude to adjust during editing.

Phone cameras shoot in JPEG (or HEIC, which is a similar processed format). The image you see immediately on your phone screen after taking a photo is a JPEG processed by the phone's camera software.

Why Do Professional Photographers Shoot RAW?

RAW files give the photographer significantly more editing latitude. A slightly underexposed RAW file can have its shadows recovered by 2–3 stops of exposure without visible degradation. A JPEG underexposed by the same amount loses detail in shadows permanently — the information simply wasn't captured and preserved. The same applies to highlights, white balance, and colour: RAW files allow corrections and adjustments that JPEG files can't accommodate without visible quality loss.

For professional work — where the expectation is perfect skin tone accuracy, recovery of detail in complex lighting, and consistent editing results — RAW is the professional standard. JPEGs are appropriate for casual photography where editing isn't needed.

What You Receive After a Session

Clients typically receive high-resolution JPEG files from their galleries — not RAW files. The RAW files are the working materials of the photographer's editing process, equivalent to an architect's calculation workings. Your delivered JPEGs are the finished result: full resolution (typically 20–45 megapixels), with full personal print licensing, ready for downloading and printing.
