RAW vs JPEG: Which Format Should You Shoot?

The format you choose decides how much information survives the shot. A JPEG is processed inside the camera: white balance, contrast, sharpening and noise reduction are baked in, the file is compressed to 8 bits per channel and typically lands at 5-10MB. It is ready to send, prints fine, and every device opens it. A RAW file keeps the sensor data - usually 12 or 14 bits per channel - with only metadata describing the settings used. Files run 20-50MB, need a converter, and look flat and dull straight out of camera because no contrast curve has been applied yet.

The practical difference is latitude. In a JPEG you might rescue half a stop of blown highlights and a stop of shadow before noise and banding appear. A RAW file typically recovers 1.5-2 stops of highlights and lets you lift shadows three or four stops while staying clean, because there is far more tonal data to work with. White balance is the other big win: on RAW it is a free, lossless slider, so a badly set tungsten or shade preset costs nothing to correct. On a JPEG, dragging the temperature slider produces colour shifts, banding and noise.

Shoot RAW when the light is hard, when the dynamic range is huge - white dresses, sunsets, backlit windows, stage lighting - or when the pictures matter commercially. Shoot JPEG when you must hand over files immediately, when card space or buffer depth is tight, or when you are learning and want to concentrate on composition. Many cameras offer RAW+JPEG, which writes both: JPEG for quick review and delivery, RAW for the frames worth editing.

A common beginner mistake is trusting the bright, punchy look of JPEG on the camera screen and only discovering a blown, unrecoverable highlight at home. Remember, though, that RAW is not a cure for poor technique: it will not fix missed focus, motion blur or a bad composition.
