I'm trying to use a simple convert command to convert my camera's raw images (Sony alpha ARW) to TIF files for further processing, but the output image is always converted to greyscale. The input images are images of the night sky so they have very little colour variation, but it's there and it's important for the output image. I tried converting to other formats like FITS and PNG24 but the result is always the same: it's converted to greyscale

OS: Linux Mint 13 Maya; ImageMagick: 8:6.6.9.7-5ubuntu3.3; dcraw: 9.19-1dhor~precise

command:
convert DSC01082.ARW tif/DSC01082.ARW.tif

Any suggestions?

How do you know they become grey? They will look greyer than in-camera jpegs, but should be colour. Have you tried conventional daylight photos?

Have you tried driving dcraw directly? That would tell you if the grey conversion was in dcraw or IM.
