Thanks for all that. (I've got an Intel i5 CPU; I think the 'Cedar' is something to do with my AMD Radeon HD 5450 graphics card.)

Interesting. When I do the command you suggested: C:\Program Files\ImageMagick-7.0.3-Q16>.\dcraw.exe -6 -T -v -O c:\x.tiff c:\RAW_CANON_EOS_600D.CR2 Loading Canon EOS 600D image from c:\RAW_CANON_EOS_600D.CR2 ...

I just installed ImageMagick on windows 10, including the 'legacy convert' option. When I open a CR2 or ORF (raw files from Canon or Olympus) in IMdisplay or if I use 'convert' or 'magick convert' at the command line, I get a pure black image (of the dimensions of the input image). Eg., here's a ...
