I have a Canon SX60, able to generate HDR pics.

I would like to know how can I detect a HDR image just checking the EXIF data, and if I can know about the different exposure details.

  • it would help if you just made a picture and posted it here, so we could have a look at its Exif. – ths Feb 19 '15 at 10:04
  • I just posted (quite) same pic, normal version and HDR version. Links blog.jcea.es/hdr_NO.jpg and blog.jcea.es/hdr_YES.jpg. Help welcome!! – jcea Feb 26 '15 at 3:30

Your posted image, when inspected with ExifTool, shows

Easy Mode                       : High Dynamic Range
Shooting Mode                   : High Dynamic Range

The exposure details are only for one of the exposures, of course.

  • Ok, Thanks. I have upgraded my "exiftool" installation and I have asked for HDR support in the Python library I am using: github.com/ianare/exif-py/issues/48 – jcea Feb 27 '15 at 3:15
  • Parsing an iOS 8 HDR picture with "exiftool" I get this tag: "HDR Image Type : HDR Image". So each vendor uses different tags. Messy :-( – jcea Feb 27 '15 at 3:27
  • funny. can a HDR image be any other type than a "HDR Image"? – ths Feb 27 '15 at 10:11

At least in some camera models it looks like Canon store the following in EXIF:

  • HDR Shooting: Enable/Disable

  • Adjust dynamic range: Enable/Disable

  • HDR Effect: Natural/Art Standard/etc.

  • Auto Image Align: Enable/Disable

What you see may depend on the tool you use. The Canon software would most likely display it. Not sure if Exiftool would.

One of the latter comments on a Lightroom Metadata plugin (link) mentions the above fields being shown by the Canon software for a 600D.

If you've done a single shot HDR image (in-camera) I suspect you won't see the range of values used in the shutter speed/aperture/ISO fields - probably just one value.

  • Pics posted!!. Help welcomed!. – jcea Feb 26 '15 at 3:32
