Image meta data

^{Originally posted by stevedee August 16, 2024} Although the text overlay module is super useful, I like to capture 'clean' images, free of clutter, once the system has been properly setup. So wondered if you could implement the addition of image EXIF data.

I notice in the c++ file: capture_RPi.cpp some notes to implement this:-

/* TODO: what exif fields should we use? if (myModeMeanSetting.meanAuto != MEAN_AUTO_OFF) { stringstream strExposureTime; stringstream strReinforcement; strExposureTime << myRaspistillSetting.shutter_us; strReinforcement << myRaspistillSetting.analoggain;

	command += " --exif IFD0.Artist=li_" + strExposureTime.str() + "_" + strReinforcement.str();
}

*/

I'd suggest as a minimum:- exposure: number (ms) gain: number auto exposure: yes/no auto gain: yes/no

Nice-to-have:- author: text camera: text lens: text camera temperature: 'C focus metric: number longitude: latitude:

Many thanks!
