255 Others
Data type: SHORT. Length: 1.
32 Flash Flash On/Off. Possible values are 1 for on or 0 for off. Data type: SHORT. Length: 1. Refer to the EXIF specification for all possible values for EXIF comments.
33 FocalLength Focal length, measured in millimeters. Data type: RasterCommentMetadataDataType.URational. Length: 1.
34 ExposureTime Exposure time, expressed as a fraction of a second. Data type: RasterCommentMetadataDataType.URational. Length: 1.
35 FNumber The actual lens F stop (ratio of lens aperture to focal length). Data type: RasterCommentMetadataDataType.URational. Length: 1.
36 MakerNote Maker note. Data type: RasterCommentMetadataDataType.Ascii. The creator of the file determines the data format.
37 UserComment User comment. Data type: RasterCommentMetadataDataType.Ascii. Length: variable. The first eight bytes specify the data format, and the remainder of the comment is in the specified format. The first eight bytes can be any of the following:
41 53 43 49 49 00 00 00 ASCII
4A 49 53 00 00 00 00 00 JIS (Japanese)
00 00 00 00 00 00 00 00 Undefined
38 SubSecTime Decimal extension for seconds that are specified in the RasterCommentMetadataType.DateTime field. Data type:RasterCommentMetadataDataType.Ascii. Length: variable
39 SubSecTimeOriginal Decimal extension for seconds that are specified in the RasterCommentMetadataType.DateTimeOriginal field. Data type: RasterCommentMetadataDataType.Ascii. Length: variable.
40 SubSecTimeDigitized Decimal extension for seconds that are specified in the RasterCommentMetadataType. DateTimeDigitized field. Data type: RasterCommentMetadataDataType.Ascii. Length: variable.
41 GpsVersionId Version number of the GPS image file directory (IFD). The current version is 2.0.0.0. This comment must be included when any GPS comments are used. Unlike the RasterCommentMetadataType.ExifVersion comment, this comment is written in bytes. A version written as 2.0.0.0 is actually 0x02000000 when coded. Data type: BYTE. Length: 4.
42 GpsLatitudeRef North or south latitude. Possible values are "N" for north and "S" for south. Data type: RasterCommentMetadataDataType.Ascii. Length: 2.
43 GpsLatitude Latitude, expressed as three RasterCommentMetadataDataType.URational values. When expressed in degrees, minutes, and seconds, latitude is written as dd/1,mm/1,ss/1. If degrees and minutes are used as the units, and minutes are written with fractions to two decimal places, then latitude is expressed as dd/1,mmmm/100,0/1. Data type: RasterCommentMetadataDataType.URational. Length: 3
44 GpsLongitudeRef East or west longitude. Possible values are "E" for east and "W" for west. Data type: RasterCommentMetadataDataType.Ascii. Length: 2.
45 GpsLongitude The longitude, expressed as three RasterCommentMetadataDataType.URational values. When expressed in degrees, minutes and seconds, longitude is written as ddd/1,mm/1,ss/1. If degrees and minutes are used as the units, and minutes are written with fractions to two decimal places, then longitude is expressed as dd/1,mmmm/100,0/1. Data type: RasterCommentMetadataDataType.URational. Length: 3.
46 GpsAltitudeRef Reference altitude. In the current version, sea level is used as the reference, which must be zero. The reference unit is meters. Data type: BYTE. Length: 1.
47 GpsAltitude Altitude, in meters, relative to the reference altitude. Data type: RasterCommentMetadataDataType.URational. Length: 1.
48 GpsTimestamp Time stamp in UTC (Coordinated Universal Time) time. The time is expressed as three RasterCommentMetadataDataType.URational values, for hours, minutes, and seconds. Data type: RasterCommentMetadataDataType.URational. Length: 3.
49 GpsSatellites GPS satellites used for measurement. The coding format is not stipulated. This comment can be used to code information such as the number of satellites, the satellite number, the satellite angle of elevation, its azimuth, and its SNR. If the GPS receiver cannot make a measurement, this comment is NULL. Data type: RasterCommentMetadataDataType.Ascii. Length: variable.
50 GpsStatus Status of the GPS receiver at when the image is recorded. Possible values are "A" when measurement in progress and "V" when measurement is interrupted. Data type: RasterCommentMetadataDataType.Ascii. Length: 2.
51 GpsMeasureMode GPS measurement mode. A value of "2" denotes two-dimensional measurement, and "3" denotes three-dimensional measurement. Data type: RasterCommentMetadataDataType.Ascii. Length: 2.
52 GpsDop DOP (data precision) value. This comment is an HDOP value during two-dimensional measurement and a PDOP value during three-dimensional measurement. Data type: RasterCommentMetadataDataType.URational. Length: 1.
53 GpsSpeedRef Unit for measuring speed. Possible values are "K" for kilometers, "M" for miles, and "N" for knots. Data type: RasterCommentMetadataDataType.Ascii. Length: 2.
54 GpsSpeed Speed of the GPS receiver. Data type: RasterCommentMetadataDataType.URational. Length: 1.
55 GpsTrackRef Reference for direction of movement. Possible values are "T" for a true direction and "M" for a magnetic. Data type: RasterCommentMetadataDataType.Ascii. Length: 2
56 GpsTrack Direction of GPS receiver movement. The range of values is 0.00 to 359.00. Data type: RasterCommentMetadataDataType.URational.

Remarks

When reading or updating Exif comments, you must specify the comment type. Comment fields are constrained by their Exif data type.

All Exif files (TIFF and JPG) or files which can contain Exif metadata (PNG, HEIC, WebP, etc) can contain the designated TIFF comments. Each TIFF comment field can contain a character string.

Note: refer to the EXIF specification for all possible values for EXIF comments.
