XMP Specification September 2005 65 XMP Schemas EXIF Schemas 4 exif:FocalLength Rational Internal EXIF tag 37386, 0x920A. Focal length of the lens, in millimeters. exif:SubjectArea seq Integer Internal EXIF tag 37396, 0x9214. The location and area of the main subject in the overall scene. exif:FlashEnergy Rational Internal EXIF tag 41483, 0xA20B. Strobe energy during image capture. exif: SpatialFrequencyResponse OECF/SFR Internal EXIF tag 41484, 0xA20C. Input device spatial frequency table and SFR values as specified in ISO 12233. exif:FocalPlaneXResolution Rational Internal EXIF tag 41486, 0xA20E. Horizontal focal resolution, measured pixels per unit. exif:FocalPlaneYResolution Rational Internal EXIF tag 41487, 0xA20F. Vertical focal resolution, measured in pixels per unit. exif:FocalPlaneResolutionUnit Closed Choice of Integer Internal EXIF tag 41488, 0xA210. Unit used for FocalPlaneXResolution and FocalPlaneYResolution. 2 = inches 3 = centimeters exif:SubjectLocation seq Integer Internal EXIF tag 41492, 0xA214. Location of the main subject of the scene. The first value is the horizontal pixel and the second value is the vertical pixel at which the main subject appears. exif:ExposureIndex Rational Internal EXIF tag 41493, 0xA215. Exposure index of input device. exif:SensingMethod Closed Choice of Integer Internal EXIF tag 41495, 0xA217. Image sensor type on input device: 1 = Not defined 2 = One-chip color area sensor 3 = Two-chip color area sensor 4 = Three-chip color area sensor 5 = Color sequential area sensor 7 = Trilinear sensor 8 = Color sequential linear sensor exif:FileSource Closed Choice of Integer Internal EXIF tag 41728, 0xA300. Indicates image source: 3 (DSC) is the only choice. exif:SceneType Closed Choice of Integer Internal EXIF tag 41729, 0xA301. Indicates the type of scene: 1 (directly photographed image) is the only choice. Property Value Type Category Description
