Maybe I'm asking a stupid question for real photographers, but I'm searching an online repository with XMP sidecar files for Darktable. Everyone knows the many instagram effects like laté and sepia and so on. Is there no place where photographers share some of this effects and editing steps in XMP sidecar files? So I can use them and learn quickly from these predefined files.
There is a LUT module in darktable now, so you can apply a LUT to your image, which is useful for all those instagram-type filters.
