I hope someone can answer this question, its been bugging me for a while now and I can’t seem to get a solid answer.
How exactly does the iPhone measure scene brightness (or luminance if you prefer) through its camera? Does it measure it off the pixels on the sensor, or does it have dedicated in lens brightness sensor(s)?
Is there a way to read this raw brightness information other than through EXIF data?
Thanks in advance,
Chris
I have determined through experimentation that Luminance is measured off the camera sensor and not from a discrete sensor through the lens. Thanks to everyone who read and/or answered this question!
Kind Regards,
Chris
