Does Sigma SD Quattro support exist?


Are the current native .x3f or .x3i Sigma files created by the SD Quattro supported?

Many thanks


Did you try the x3f?

RawTherapee supports most raw formats, including Pentax and Sony Pixel Shift, Canon Dual-Pixel, and those from Foveon and X-Trans sensors. If you’re wondering whether it supports your camera’s raw format, first download RawTherapee and try for yourself.



There is support for what looks like the DP 1 Merril a camera produced in 2012. There are only 2 options under the demosiacing tab for this camera, Raw White Point and Dark Frame and the demosiacing looks terrible btw.

RT 5.4-rc2 doesn’t display .x3f files produced by the latest Sigma cameras, the SD Quattros, nor does it display …x3i files produced by these cameras. .x3i are files made up of 7 separate exposures which are the combined in post via Sigma SPP into 1 non HDR file with extended dynamic range and detail.

Are there plans to update RT to support these wonderful Sigma cameras?

many thanks in advance
