Understanding Exif Metadata

To obtain the information of the EXIF tags of an image, the _getexif() method of the image object can be used. For example, we can have a function where, from the image path, we can return information from EXIF tags.

The following functions are available in the extractDataFromImages.py file in the exiftags folder:

def get_exif_metadata(image_path):    exifData = {}    image = Image.open(image_path)    if hasattr(image, '_getexif'):        exifinfo = image._getexif()        if exifinfo is not None:            for tag, value in exifinfo.items():                decoded = TAGS.get(tag, tag)                exifData[decoded] = value decode_gps_info(exifData) return exifData

This information can be improved by decoding the information we have obtained in a latitude-longitude values ...
