Embedding metadata in a photo is a bit like turning over a snapshot to scribble your name and a note on the back of the picture. The information travels with the photo, where ever it goes. Yes, it takes an extra step to view the metadata on a digital file, in the same way that you have to turn over a photo to read what’s recorded on the reverse.
Have you ever viewed the information for a digital photo and wondered where it came from and what it means? This information is called metadata, or “data about data.” To understand how metadata works and why it’s useful, it’s helpful to understand how capture devices organize images internally or on a memory card.
Every image can include two different kinds of data: Exchangeable image file format (EXIF) and International Press Telecommunications Council (IPTC). Some data are automatically recorded by the camera and others are available for your input. This data is used to sort and organize images in the camera and when transferred to your computer.

Both EXIF and IPTC data are referred to as metadata and provide information about your digital image. The data is embedded in the digital file itself for JPG and TIFF format images, or saved in a companion “sidecar” file for RAW images. There is some overlap in data between the two sets of data.
Learn to use metadata as part of your digital image workflow in my book How to Archive Family Photos (FamilyTree Books, 2015).
Typical Exif information includes all kinds of information about the camera make and model, resolution, exposure, location and other settings, but most importantly for organizing files, Exif records date and time of capture with a unique file name for each image. The date and time is used to organize image files in folders and the unique file name identifies individual image files. Because Exif data is added automatically by your camera or capture device, you can’t really input Exif data except to insure that your camera is set to record the correct date and time.
In Adobe Lightroom, the EXIF panel looks like this:
The IPTC data set is usually added by the user in the form of title, caption, subject, photographer, copyright, and so on. Originally designed to help news providers locate and credit photo sources, IPTC data is a genealogists friend when it comes to adding information about the people, places, and events shown in an image. Some IPTC data can be set automatically but most information must be individually recorded.
The IPTC data looks like this:
Using embedded metadata is a bit like writing your name and phone number on the back of a snapshot. The information travels with the photo, and anyone who opens the file to look at the Properties or Information will be able to read the information you’ve recorded. For photos that will be shared on a public or online website, it’s a good idea to add a few basic lines of information so that someone down the line can learn where the photo came from and who is pictured in the image. The most basic data is usually enough, including:
- Your name and email as the current owner of the image
- A short title identifying the photo subject
- A brief description or caption identifying any people, events, or dates
To add IPTC metadata to individual photos, you can use the Properties panel on your PC or the Get Info option on your Mac.
On a PC, right-click on the image and select Properties. Rename the file in the main window [A]. Click the Details tab to add tags and keywords [B].
Update: As noted in the comments, adding metadata through the Windows Properties feature may not the best option. Metadata is a “funny” thing. It doesn’t always “stick” so that it’s visible in other applications. Before embarking on a large project renaming images, test a few files and open in other programs to confirm that the metadata has transferred. Using the SAVE AS or EXPORT command may work to embed the added metadata.
On a Mac, select an image and open the Information window with Command-I. Rename the file [A] and add tags and keywords in the window [B].
When organizing large image collections it’s usually most efficient to add tags, keywords, and captions to the metadata using batch-editing functions in a photo management program such as Adobe Photoshop Elements, Adobe Lightroom, Picasa, or Xnview.
My favorite tagging and data tool is Adobe Lightroom where I can add keywords, event names, and unique filenames as photos are imported from my memory cards or mobile devices. If you’re working with a limited number of photos, however, it’s a quick and easy task to add metadata to a few images with the Properties or Information panel. Macgo mac blu ray player 2 17 2.

-->The following example demonstrates how to re-encode an image and its metadata to a new file of the same format. In addition, this example adds metadata to demonstrate a single-item expression used by a query writer.
This topic contains the following sections.
Prerequisites
To understand this topic, you should be familiar with the Windows Imaging Component (WIC) metadata system as described in the WIC Metadata Overview. You should also be familiar with the WIC codec components as described in the Windows Imaging Component Overview.
Part 1: Decode an Image
Before you can copy image data or metadata to a new image file, you must first create a decoder for the existing image that you want to re-encode. The following code demonstrates how to create a WIC decoder for the image file test.jpg.
The call to CreateDecoderFromFilename used the value WICDecodeMetadataCacheOnDemand from the WICDecodeOptions enumeration as the fourth parameter. This tells the decoder to cache the metadata when the metadata is needed, either by obtaining a query reader or by using the underlying metadata reader. Using this option enables you to retain the stream to the metadata, which is required for performing fast metadata encoding and enables lossless decoding and encoding of JPEG images. Alternatively, you could use the other WICDecodeOptions value, WICDecodeMetadataCacheOnLoad, which caches the embedded image metadata as soon as the image is loaded.

Part 2: Create and Initialize the Image Encoder
Google seo checker. The following code demonstrates the creation of the encoder you will use to encode the image you previously decoded.
A WIC file stream piFileStream is created and initialized for writing to the image file 'test2.jpg'. piFileStream is then used to initialize the encoder, informing the encoder where to write the image bits when the encoding is complete.
Part 3: Copy Decoded Frame Information
The following code copies each frame of an image to a new frame of the encoder. This copy includes size, resolution, and pixel format; all of which are necessary to create a valid frame.
Note
JPEG images will only have one frame and the loop below is not technically necessary but is included to demonstrate multi-frame usage for formats that support it.
The following code performs a quick check to determine whether the source and destination image formats are the same. This is needed as Part 4 shows an operation that is only supported when the source and destination format are the same.
Part 4: Copy the Metadata
Note
The code in this section is valid only when the source and destination image formats are the same. You cannot copy all of an image's metadata in a single operation when encoding to a different image format.
![Meta Meta](https://els-jbs-prod-cdn.jbs.elsevierhealth.com/cms/attachment/2485eef6-e1ce-499b-99e1-02b68cf61d14/gr1.jpg)
To preserve metadata while re-encoding an image to the same image format, there are methods available for copying all the metadata in a single operation. Each of these operations follows a similar pattern; each sets the decoded frame's metadata directly into the new frame being encoded. Note that this is done for each individual image frame.
The preferred method for copying metadata is to initialize the new frame's block writer with the decoded frame's block reader. The following code demonstrates this method.
In this example, you simply obtain the block reader and block writer from the source frame and destination frame, respectively. The block writer is then initialized from the block reader. This initializes the block writer with the pre-populated metadata of the block reader. To learn additional methods for copying metadata, see the Writing Metadata section in the Overview of Reading and Writing Image Metadata.
Again, this operation works only when the source and destination images have the same format. This is because different image formats store the metadata blocks in different locations. For instance, both JPEG and Tagged Image File Format (TIFF) support Extensible Metadata Platform (XMP) metadata blocks. In JPEG images, the XMP block is at the root metadata block as illustrated in the WIC Metadata Overview. However, in a TIFF image, the XMP block is embedded in the root IFD block.
Part 5: Add Additional Metadata
The following example demonstrates how to add metadata to the destination image. This is done by calling the query writer's SetMetadataByName method using a query expression and the data stored in a PROPVARIANT.
For more information on the query expression, see the Metadata Query Language Overview.
Part 6: Finalize the Encoded Image
The final steps for copying the image are to write the pixel data for the frame, commit the frame to the encoder, and commit the encoder. Committing the encoder writes the image stream to the file.
The frame's WriteSource method is used to write the pixel data for the image. Note that this is done after the metadata has been written. Iexplorer 4 2 0. This is necessary to ensure that the metadata has enough space within the image file. After the pixel data is written, the frame is written to the stream using the frame's Commit method. After all frames have been processed, the encoder (and thus the image) is finalized using the encoder's Commit method.
Once you commit the frame, you must release the COM objects created in the loop.
