SD1 to PSD Conversion: FAQ

What are SD1 files?

The SD1 extension is attached to RAW images captured using some models of Sigma cameras. Sigma is a Japanese brand producing various types of photographic devices and cameras. The brand is best known for its lenses that can be used on cameras manufactured by several other companies, including Nikon, Canon and Panasonic. SD1 is part of a group of extensions attached to images shot in RAW mode on Sigma devices, including SD0 and SD2. All are considered rare and probably difficult to open using regular image viewers.

What are PSD files?

PSD is the default format for handling images using Adobe Photoshop and it represents a layered image file. PSDs allow later editing of available layers, including transparency, masks, alpha channels and texts, among others. After applying all desired editing, PSD files can be saved in Photoshop under more easily recognizable formats, such as JPEG or PNG, which are also smaller in size but flatten the image and hence do not allow later editing of layers.
