Hello Alexey!

Is it possible to read the exposure value / exposure compensation of a photo with python?
Can't find it under camera.photo.meta ...

Thank you!

Hello mcstieg,

Which EXIF tag you are referring to? Can you specify its name and, if possible, provide any sample image, where the tag is present, but is not added to the camera.photo.meta dictionary?

As a workaround, you can try to use camera.photo.imageMeta(), but note that this method reads the image directly.

This doesn't show the value I am looking for.

I've attached an example image for you (Had to fix file size...).
You can upload it to http://exif.regex.info/exif.cgi if you want to.

Exposure Compensation would be good to know in my case.
Thank you!

Hello mcstieg,

Thank you for additional information.

We will extend the list of supported EXIF tags in the next update, so this value will be available via camera.photo.imageMeta() call.

Are you interested in any other tags that are not yet available via Python API call?

Thank you Alexey!

Of course, I want to use this chance ...
  • exposure program
  • exposure compensation
  • subject distance
  • metering mode
  • lens model
  • light source
  • flash
  • white balance
  • scene capture type
  • exposure mode
  • digital zoom ratio
  • contrast
  • saturation
  • sharpness

;D
