Program Support
Exif data are embedded within the image file itself. While many recent image manipulation programs recognize and preserve Exif data when writing to a modified image, this is not the case for most older programs. Many image gallery programs also recognise Exif data and optionally display it alongside the images.
Software libraries, such as libexif for C and Adobe XMP Toolkit or Exiv2 for C++, Metadata Extractor for Java, or Image::ExifTool for Perl, parse Exif data from files and read/write Exif tag values.

“In 1862 the congregation of the church forwarded the church bell to General Beauregard to be melted into cannon, “hoping that its gentle tones, that have so often called us to the House of God, may be transmuted into war’s resounding rhyme to repel the ruthless invader from the beautiful land God, in his goodness, has given us.””
—Federal Writers’ Project Of The Wor, U.S. public relief program (1935-1943)
“The purpose of punishment is to improve those who do the punishing—that is the final recourse of those who support punishment.”
—Friedrich Nietzsche (1844–1900)
