exif: {"Image DocumentName": "Frequency and Period Frequency - the number of wavelengths that pass a fixed point each second; is expressed in hertz (Hz)", "Image ImageDescription": "You can find the frequency by counting the number of crests or compressions that pass every second. Period - the amount of time it takes on wavelength to pass a fixed point is expressed in seconds. You can find the period by counting the number of seconds between each crest or compression.", "Image XResolution": "200", "Image YResolution": "200", "Image ResolutionUnit": "Pixels/Inch", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
