JPEG Image Orientation and Exif - jdhao's blog

The other day I came across a strange bug during work. My colleagues gave me some photographs taken with a smartphone. On their machines (Windows 7), all the photos were shown correctly in landscape mode. However, when I checked those photos, I found that some of those photos were shown in portrait mode (rotated 90 or 270 degrees) or upside-down (rotated 180 degrees). I was curious what happened and learned about Exif and all its related stuff.

I found another key that needed to be 'tweaked' on ONE out of several photos that I scanned from slides: exif:DigitalZoomRatio needs to be a Rational, and since I didn't care about the value I set exif_dict = ['Exif'][41988] = (00,00)
