Exposure values from camera can be acquired when you take picture (without saving it to SavedPhotos). A light meter application on iPhone does this.
What is the appropriate way to get these values?
The aforementioned application does this on iPhone 3GS only, so I guess it may be somehow related to EXIF data which is populated with this information when the image is created.
Does anyone have a working code example for taking these camera/photo setting values?
Thank you.
