SD2 files: Frequently Asked Questions
What are SD2 files?
SD2 is also known as a Dali Raw image and represents a digital photo shot using a Sigma camera or other photographic device. Other Dali Raw images include SD0 and SD1, all of which are considered rare and difficult to access without prior conversion to more popular formats. SD2 files contain RAW photos that are shot without any predefined automatic interference from the part of the digital camera, allowing the lens to capture the image as close as possible to what you can see with your naked eye. RAW images can only be used after applying digital post-processing.
