I'm seeing about 25 dead pixels (always off) in the same position in RAW files from my GX7 when using certain RAW processors with noise reduction turned off (e.g. DXO Optics Pro and ACDSee Pro). I never see the dead pixels in JPG images showing the camera's dead pixel mapping and interpolation algorithms are correcting for dead pixels before exporting an image. All RAW processors remove the dead pixels when noise reduction is enabled and Lightroom seems to remove them by default. I'm trying to work out if the detection of dead pixels by these RAW processors is normal or whether I need to return the camera under warranty. Please advise how Lumix cameras handle dead pixels in RAW data - which of the following is correct? 1. The GX7 camera maps the dead pixels and exports a clean RAW image containing no dead pixels in the image unknown to the camera. If any further dead pixels are present (unknown to the camera), then the RAW processor should remove them. 2. The GX7 camera maps the dead pixels but these are not corrected in the RAW image. The RAW processor is therefore required to correct all dead pixels including those already known to the camera. 3. The GX7 camera maps the dead pixels and exports a RAW file with no image corrections for dead pixels but includes a list of dead pixel locations known to the camera. The RAW processor may use the camera's dead pixel information or may process the RAW image from scratch ignoring the known dead pixel data from the camera.
