My first post here, so hello everyone
I have been using RawTherapee (5.8.0 Mac) for a few months now and I love it. I’ve been getting great results with exposure, colour etc. but I’m having trouble with accentuated grain on my images. After processing, I’m seeing a crystaline grain pattern which isn’t there on the camera’s JPEG output. I’m using an Olympus OM-D EM-5 Mkii. Please see the below examples (click to zoom for better detail). The bee is at ISO 200 while the wind turbine is at ISO 800.
I expect to have some grain, especially at ISO 800 and with increased contrast, but it looks like RawTherapee really makes a right meal of it. Is this something other people have experienced? Is this to do with the demosaicing? Is there something I need to know about the EM-5 and how to treat images from it?
I would love to resolve this so that my processed raws look as smooth as the JPEGs off the camera.
Thanks in advance
