Linux: Batch Convert RAW to JPG or PNG
Posted by michael on Saturday, 8 August 2015
Batch conversion of RAW images (e.g. Canon CRW og Nikon NEF) to JPEG
Get da stuff:
sudo apt-get install dcraw netpbm
Descend into directory containing the raw files, say they're Canon RAW images called xxxxxx.CRW and you want JPEGs:
for filename in *.CRW ; do dcraw -c -w "$filename" | pnmtojpeg > "$filename.jpg" ; done
...or if you're a Nikon guy/gal (aren't we all, really? Deep inside?), and you want PNGs (yes we do! And we want them now!):
for filename in *.NEF ; do dcraw -c -w "$filename" | pnmtopng > "$filename.png" ; done
**** THE END ****
