![]() ![]() We consider embedded metadata to be an ideal vehicle to convey the metadata from place to place, but it's not quite as useful as the ultimate repository for this information. If the images are offline, then the information may not be available. Additionally, embedded metadata is only available when the file is visible to the computer you're using. The first is that the information about your images will be scattered throughout the collection, rather than gathered together for a comprehensive view of the collection. Accordingly, the metadata is less likely to get separated from the file than other types of metadata. This information lives in the file itself, and can be carried from place to place as the file is transferred. Let's look at these three homes.įigure 1 Metadata can live in one or more of these places: the file, a sidecar file or a catalog.įile types with robust XMP support, such as TIFF, JPEG, PSD and DNG, can all contain virtually unlimited metadata. Each of these has advantages and disadvantages. ![]() ![]() There are three basic places metadata can live: embedded in the file itself, in a sidecar file, or in a catalog. You would have just lost a very significant portion of the collection's value.įortunately, making use of and preserving metadata is not that difficult, once you understand where it lives, how to move it from place to place, how to back it up, and how to attach it to images. Now imagine stripping all the metadata from this collection, and being left with original image data – back at square one. Imagine an image archive of hundreds of thousands of photos where the best images are tagged with high ratings, images are organized around subject matter, and they are adjusted to fulfill the vision of the photographer. You'll need to get an understanding of where the metadata lives, and how to manage and preserve it. If you're going to construct a safe and effective workflow, you'll need to handle this metadata properly. For raw images that are finished with PIEware, the "only" thing that really changes about the file, from the time of capture onward, is the metadata that is associated with it. And some metadata can be used to adjust the picture to your liking. Some can describe who owns the photo and how to contact the owner. Some metadata can be used to describe the image and how much you like it. Metadata can be incredibly useful in both the short and long term. ![]()
