Aperture & Shutter Speed Information Extraction

Good day,

I am attempting to extract an image's aperture and shutter speed information using MatLab to perform some calculations and processing, and I am wondering if I am able to do so using any particular functions.

Regards

You might be able to use exifread() or the newer imfinfo

But the information might not have been recorded in exif (e.g. on my camera it does not record aperture if the camera is set to its Automatic setting mode.)

If your image is TIFF the image might also be recorded as a TIFF tag; see http://www.mathworks.com/help/matlab/ref/tiffclass.html
