I have several rggb cfa images in png format. I want to demosaic them using RawTherapee. I am aware that RawTherapee only allows demosaicing of actual raw images (how anyone actually thinks that this is a good idea I can’t understand). I tried converting the images into raw using GIMP 2, XnView and Fiji. However, RT doesn’t even detect the files. I exported the images as 8, 16 and 32bit images in both RGB and grayscale. Someone also suggested to export to .tif and then to rename the files to .dng. This also didn’t work.
