I set up a folder for incoming files and it automatically resizes, renames, and converts them into the formats I need. It's like having a personal assistant!"

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.
