I have often heard the word Metadata and never really understood the meaning or its function. Having now investigated what Metadata actually is. I can tell you it’s basically data added to data. For example an image may include metadata that describes how large the image is, the image resolution and when the image was created. The metadata I have just described is generally automatically generated when taking an Image. But you can also add you own metadata in software packages such as Light Room and Photoshop. You might want to define your image adding more metadata manually by adding keywords such as Wedding, Family or Holiday. The metadata is always added before the images are imported into your chosen software.
