DSLR vs AI Metadata: What Really Differs Under the Hood

Why Detection Works: Metadata Signatures

Modern detectors do not need to look at pixels. A raw AI file screams "not a camera" through its metadata alone.

DSLR / Mirrorless Metadata

• Make/Model: Canon, Sony, Nikon, Fujifilm
• LensModel with focal length range
• ExposureTime, FNumber, ISO, ExposureBias
• WhiteBalance, MeteringMode, Flash
• MakerNote: Vendor-specific binary blob (Canon CR2, Sony ARW)
• SubIFD with thumbnail preview

Typical AI File Metadata

• No Make/Model
• Software tag: "Midjourney", "DALL-E", "Stable Diffusion"
• IPTC DigitalSourceType = trainedAlgorithmicMedia
• C2PA manifest with cryptographic signature
• No MakerNote, no SubIFD

How to Bridge the Gap

Injecting realistic iPhone EXIF is the cleanest strategy — Apple metadata is trusted, common, and hard to distinguish from real captures. InstaLabelRemover does this automatically.
