Tagged-Format Metadata

As is written in the Metadata Types, this metadata format defined in TIFF Rev. 6.0 is called Tagged-Format Metadata in this User Guide.

Sorting Items

You can sort by Tag Number, Tag Name or Custom.

Select the metadata type TIFF, Exif or GPS, and then do one of the following.

If you choose sort by Custom, you can drag-and-drop the metadata items in the order you want.

Editing TIFF, Exif
  1. An editable item. Click to edit an embedded metadata item.
  2. An addable item. Click to add a metadata item into image file(s).
  3. Pop-up menu of addable items. Choose an item to add metadata into image file(s).
  4. Remove selected metadata items.
  5. Switch to show only embedded metadata items or to show embedded and addable metadata items.

Double click a metadata item or click or to show the editing sheet for the Tagged-Format Metadata.

♦ Rational Type (e.g. Exposure Time, F Number, Shutter Speed Value)

Recorded two integer values. The first is the numerator and the second is the denominator.

You can also enter decimal fraction or common fraction value directly like the following.

♦ Integer Type (e.g. Focal Length In 35mm Film, Photographic Sensitivity)
♦ Character Type (e.g. Image Description, Copyright)

The most of the character type items of Tagged-Format Metadata can only use ASCII code.

The User Comment Tag #37510 can use the Unicode and JIS code. You should not use the JIS code characters because these are not recognized in most other image viewer apps.

※Unicode Characters Garbled
In Photo Meta Edit v2.2.6, the unicode encoding to use has been changed to become adapted to Apple's Preview version 8.1 or later.
・Up until the version 2.2.5: only used UTF-16BE
・Since the version 2.2.6: UTF-16BE and UTF-16LE are used respectively according to the endianness of the metadata

Endianness is byte order to store data in memory. There are two endiannesses, Big-Endian (BE) and Little-Endian (LE). The LE is that the least significant value in the sequence is stored first. The Tagged-Format metadata (including Exif, GPS) is stored by one of the endiannesses.
You can see which one a metadata is stored by on the metadata type list as below.

Photo Meta Edit version 2.2.6 or later stores and displays unicode characters of TIFF (BE) by UTF-16BE, and of TIFF (LE) by UTF-16LE.

The unicode characters of TIFF (LE) that written by Photo Meta Edit version 2.2.5 and earlier are garbled in version 2.2.6 or later. And also in Apple's Preview version 8.1 or later. Because these are stored by UTF-16BE.

♦ Fixing Garbled Characters
You can fix it in either of the following ways.

1. On the items view:
Choose the TIFF (LE) on the metadata type list, choose an item of garbled unicode characters. Show the context menu, and then choose "Reverse Byte Order".
2. On the Favorites view:
Click the "!" button to show the action view, and then click the "Reverse Byte Order" button.

The Exif specification does not specify an encoding of unicode. It allows you to use the other encodings of unicode. There may be exif editor apps that does not use the UTF-16 encodings. If garbled unicode characters that stored by other than UTF-16 encodings (e.g. UTF-8, UTF-32) cannot be fixed by the below steps.

♦ Choosing Pre-defined Type (e.g. Metering Mode, Light Source, Scene Capture Type)

Choose a value from pre-defined data.

Copy & Paste

Select metadata item(s) you want to copy, and then choose Edit > Copy.

Select image file(s) you want to paste, and then choose Edit > Paste.

Batch Functions for Date-Time metadata

For multiple images, you can use the batch functions to change a Date-Time metadata item of the following.
- Tag #306: Date Time (TIFF)
- Tag #36867: Date Time Original (Exif)
- Tag #36868: Date Time Digitized (Exif)

Select image files you want to edit, and then select "TIFF" or "Exif" in the Metadata Type List

Click of a Date-Time metadata item to show the Batch editing sheet. And then choose a function from the function pop-up button.

Backward, Forward

For Example: Forward 30 minutes

For Example: 10 minute intervals

DSCN00732012:12:24 19:02:392012:10:15 15:18:21

You can drag and drop files to change the order of them if necessary.

Date Time

Set the same date time values in each files.


The values of batch editing time fields are applied in a left-to-right order.
Years → Months → Days → Hours → Minutes → Seconds → Subseconds.


It might be appropriate to use day values for incrementing/decrementing. If you need to calculate dates, click the "Date Calculator..." button.


The subsecond metadata are stored in the Exif, separately from date-time metadata.

- Tag #37520: Subsecond of Date Time (#306 in TIFF)
- Tag #37521: Subsecond of Date Time Original (#36867 in Exif)
- Tag #37522: Subsecond of Date Time Digitized (#36868 in Exif)

If you enter a one-digit subsecond value, it will be converted to the two-digit value (centiseconds). Example: 2 → 20

In the Batch editing sheet, you can enter a two or three-digit value (centiseconds or milliseconds).

Editing GPS

To add GPS Coordinates metadata. Do one of the following:
- Choose Metadata > Add > GPS > "Registered Coordinates"
- Choose Metadata > Add > GPS > Custom... and then ckick on the Map

You can edit the GPS Coordinates by clicking on the Map.

Searching GPS Coordinates

Enter keywords, address, street name, and so on in the search field. And then press the return key.
The search results are displayed on the Map.

You can also see them in the Location pop up menu.

To change GPS Coordinates. Do one of the following:
- Choose a result of location in the Location pop up menu.
- Click a blue flag, then the infomation is appeared. Click the Set button.

Showing Direction on the Map

The following three types of GPS direction-related metadata can be displayed on the map.

- Tag #15: Track
- Tag #17: Image Direction
- Tag #24: Destination Bearing

To add/edit the directions, enter a value (0.00 ~ 359.99) or use the circular dials.
North: 0.0, East: 90.0, South: 180.0, West: 270.0

You can choose how to display it like the below, Line, Delta and Camera, by clicking the three-gray-dot button.
