Questions & Answers
BAY images: Frequently Asked Questions
What are BAY files?
Bay is a type of raw photo format that is used by some digital cameras. It is also known as the Bayer filter format, named after the company that developed the technology. In this format, the camera sensor captures data in a single layer of pixels that are filtered with red, green, and blue filters. The resulting image is then demosaiced to produce a full-color image. Bay raw files contain uncompressed and unprocessed data from the camera's sensor, which allows for greater flexibility in post-processing. However, they require specialized software to edit and convert to other image formats.
