> Photo formats explained

Go to the Settings > Camera > Formats and choose a format. High Efficiency creates a lighter HEIC image file that takes up less space on your iPhone, but it will suffer from compression artifacts. Most Compatible creates a compressed JPEG that contains more information and is easy to share online. Apple ProRaw file is uncompressed, so it is packed full of data that the Photos app can use to restore missing tonal details without adding artifacts. ProRAW creates much larger files but produces the best results.
