STI to PDF Conversion: FAQ

What are STI files?

STI is a format associated with shooting in RAW mode with Sinar cameras, and has a similar function to the CS1 format. Well-known among photography aficionados, the Sinar brand was founded in the 1940s in Switzerland and has ever since produced several models of large and medium sized cameras. Most of these cameras are conceived as integrated systems and include parts that can be changed between different models. Shooting STI images with a Sinar camera results in creating RAW images that can be processed with a specialized editing software so as to create high quality images, which are more suitable for print than other compressed formats, such as JPEG.

What are PDF files?

PDF (Portable Document Format) is one of the most popular formats used for storing document files which include both text and graphics.

Moreover, they can offer decent image quality in a compressed format and can be secured with passwords or watermarks.
