+Custom profiles for Sigma or Fuji cameras are not visible
Until fully supported by Adobe, DNG profiles made for Raw images taken with some SIGMA or Fuji camera models will not appear as available in Adobe® Photoshop® Lightroom® or Adobe Camera Raw (ACR) after restart. If the only option you see under the Camera Calibration drop down menu is "Embedded" this may be the case for your Raw files.
In order to apply a profile to these images first convert them to a DNG format. Your custom profile will then be available in the Camera Calibration dropdown list when the DNG image is selected.
