What about access to the raw picture data?
The more ambitious camera people keep fussing about this,
but most of them seem to use some special plugin for Photoshop
GIMP or whatever. Is DNG (by Canon) going to become
a _standard_, and are generic tools (e.g. raw files as mass storage)
available?
Cheers, Martin

Being able to access raw image data is really a camera issue rather than Linux software issue, since most cameras don't save raw image files. If your camera is storing raw image files, you should be able to copy them off as easily as jpeg files.
To display the raw images, you can use the dcraw tool (or a program embedding it, such as the gimp plugin you are probably thinking of).
As for DNG, it is an Adobe spec and its adoption is probably still a way off (if it is adopted at all).

ok, I think I've got the point now. And sorry for mixing up Canon and Adobe.Regards, Martin

regarding raw: look at "http://www.cybercom.net/~dcoffin/dcraw/" I use dcraw for my Canon Powerhot G2 and it works very well. But sometimes you need some tweaking to get the colors right (white correction). Especially useful is the 16bit option for difficult pictures. But unfortunately there is no linux programm to handle these 48bit tiffs.

But unfortunately there is no linux programm to handle these 48bit tiffs.What kind of handling do you need? The old version of NETPBM handled 16bps images in text mode just fine (and could be compiled to do some level of binary-mode support, IIRC); I'd be surprised if the new version has lost that capability. Of course, you'd have to handle EXIF stuff separately, and it can take some experimentation to get the right set of commands piped together, but it always seemed to work pretty well for me. Can't say that I've done any 16bps work in recent years, though.

dcraw is a somewhat basic tool. Use ufraw.

There _were_ at least two such software packages.
nip may be one of them, I don't remember the name of the second -- you could try too google up message in news://fido7.ru.linux ("Alex Korchmar nip") -- he was asking this and got a few surprising answers last autumn or even winter.
