What is metadata?

When acquiring images in microscopy, the image files that are stored contain two main things:

  1. image data, which is essentially 'pixel values'
  2. metadata, information on the image data including pixel size, bit depth, dimension and objective information, etc.

Metadata is essential to correctly read image data; for example, to have accurate measurements, the image needs to be calibrated according to the correct/associated pixel size. Saving and preserving metadata is key in quantitative image analysis.

How can I see my image's metadata?
