Can you identify which camera captured a JPEG from its metadata?

I have a set of JPEG images and need to report the camera type used to capture them. I don’t have access to the original photographers, so I’m trying to determine this from the files themselves. Is the camera model normally stored in EXIF or other image metadata, and how can I check it? If the file has no camera information, can the camera still be identified reliably from the JPEG alone?

The images might or might not indicate a camera in Exif metadata. The software ExifTool can be used to check.
However, Exif data can be added or removed arbitrarily anywhere in the chain of control for an image.
This means the value of a camera or anything else in the metadata depends on what it means to know something in your specific context. Sometimes it might be ok to trust it. Sometimes it might not.
Generally if which camera really matters, then there’s less reason to trust the Exif data without a clear “chain of custody.”
If it doesn’t really matter, then it is simply a matter of context norms. What is a reasonable basis for including a fallible claim as to camera.

Sometimes. JPEGs often contain EXIF metadata with fields such as camera make and model, and a tool like ExifTool can read it. But that information may be missing, stripped out, altered, or added later during editing or export.
So:
- If EXIF includes a camera make/model, that may be useful evidence.
- If EXIF does not include it, you usually cannot reliably determine the camera from the JPEG alone.
- Even when present, metadata is not guaranteed to be trustworthy unless you have a clear chain of custody for the files.
In other words, metadata can tell you what the file claims, but not necessarily prove which camera actually captured the image. If the camera type is important for compliance or validation, the safest approach is to rely on controlled source files and documented provenance rather than JPEG metadata alone.
