A raw file is measurement data; a JPEG is a finished interpretation of it. That one difference explains almost every practical consequence of choosing between them.
A raw file is what the sensor recorded; a JPEG is a finished picture the camera made from it. Shoot and send raw when a frame needs room to move — mixed light, exposure recovery, highlight headroom or a large print. JPEG is fine when exposure and white balance are right in camera and the work is cosmetic, which is more often than raw-only advice admits.
A JPEG has already had white balance, a tone curve, sharpening, noise reduction and colour applied inside the camera, and then been compressed, with the data that did not survive thrown away. Almost every practical difference between the two formats comes from that.
What raw keeps that JPEG discards
Bit depth. Raw files are usually 12 or 14 bits per channel; JPEG is 8. That is thousands of tonal levels per channel against 256. The gap shows where tones sit close together — a sky gradient, a shadow you want to lift, skin in soft light — because 8-bit data runs out of steps and starts to band.
Highlight and shadow headroom. A raw file often holds recoverable detail in highlights and shadows that the JPEG has already clipped. How much depends on the camera and the exposure, but once the JPEG has clipped it, it is gone.
White balance as a setting. In raw, white balance is applied during processing and can be changed without penalty. In a JPEG it is baked in, and correcting it means pushing already-compressed values around, which is where colour starts to break.
No compression artefacts. JPEG compression discards detail in blocks. On smooth areas — sky, skin, a plain backdrop — those blocks appear once you start editing, and each later adjustment makes them worse.
Control over demosaicing and noise reduction. The camera's JPEG is processed for a general case. A raw processor lets you make those choices for this frame.
When JPEG is fine
The usual advice is more absolute than it needs to be.
Event work in consistent light, with exposure and white balance right in camera and a web-sized deliverable. The extra headroom buys little, and smaller files are faster at every step.
Sports and long bursts, where buffer depth is the limit and only a handful of frames will be delivered.
Same-day delivery, where the workflow is shoot, cull, light correction, send.
Tight storage or transfer. A raw archive is several times larger, and that is a real cost.
The practical test: if exposure and white balance are right in camera and the frame needs cosmetic work rather than tonal recovery, JPEG costs you very little.
When raw is the only sensible choice
- Mixed or difficult light, because white balance stays a setting rather than damage to repair.
- Underexposure you plan to lift, because the shadow data is still there.
- Any risk of blown highlights, because there is headroom above the JPEG's clipping point.
- Print at size, because 8-bit banding shows on paper.
- Frames going to a retoucher for tonal or colour work, because they can only use the latitude you send them.
Shooting RAW+JPEG
Worth it if your cards and workflow can take the extra data. The JPEGs give instant previews and quick turnaround, and the raw files are there for the frames that need rescuing. The cost is storage and a slightly more complicated import. For photographers whose work is mostly quick delivery with the occasional difficult frame, it is a sensible middle ground.
What to send a retoucher
Raw if the work involves exposure, white balance, shadow or highlight recovery. Include a reference showing how you want the frame to look, or say which processing you have already applied.
Layered TIFF or PSD if you have already done work you want kept.
Full-resolution JPEG if exposure and colour are already right and the work is cosmetic: skin, distractions, cleanup. That is a professional choice, and it makes transfers much faster.
Never a web-sized JPEG when you need print-ready output. Nothing restores resolution that was never sent.
16-bit, when you send a TIFF
A 16-bit TIFF is worth the extra size when the frame will get significant tonal work, because every curve, every dodge and burn stroke and every colour shift is calculated in steps, and 8-bit runs out of them. Bit depth and colour space have to be chosen together, as sRGB vs Adobe RGB explains. For a cosmetic retouch on a well-exposed frame, 8-bit is fine.
The format question matters most on frames that need recovery, mixed-light correction or print output. High-End Photo Retouching is where that kind of work usually sits, and its Editorial / Campaign package lists delivery for web or print.
Deciding per job, and what to keep
The format choice does not have to be permanent. A studio session with controlled light and a same-day web delivery is a different problem from an evening reception under mixed light, and it is reasonable to answer differently for each.
The archive is a separate decision. Raw files are the most flexible thing to keep and the most expensive to store. For jobs that are finished and unlikely to be reworked, some photographers keep the layered or 16-bit masters of the delivered frames and fewer raw rejects. Whatever you choose, decide it per type of job instead of letting a full drive decide it for you.
Common questions
Is shooting JPEG ever professional? Yes. Event work in consistent light, with exposure right in camera and a web-sized deliverable, loses little to JPEG and gains speed at every step. The test is whether the frame needs tonal recovery or only cosmetic work.
How much more can a raw file recover? It depends on the camera and the exposure. A raw file usually holds highlight and shadow detail that the JPEG has already clipped; bracket a test scene with your own camera to see how much.
Should I shoot RAW+JPEG? It is reasonable if your cards and workflow can take it. The JPEGs give quick previews and fast delivery, and the raw files are there for the frames that need rescuing.
Does 8-bit versus 16-bit matter? For significant tonal work, yes: every curve and dodge and burn stroke is calculated in steps, and 8-bit runs out and bands. For a cosmetic retouch on a well-exposed frame, 8-bit is fine.
Should I apply my preset before sending raw files? Either send the raw files untouched with a JPEG showing your processed look, or send processed TIFFs. Say which you have done, so the retoucher does not undo your processing or apply it twice.
