Hello out there.
I used to scan my negatives in maximum resolution on my Minolta
Dimage Scan Dual III and then save as TIF.
Then I did some elementary editing like rotating and cropping.
After that I burned the TIFs on DVD. From these "originals" I created
downsized JPGs. Now that I have switched to digital photography I want
to do the same thing with RAWs. Is there any program where you can edit
RAW pictures and save them back as RAW?
Regards, Janne.

Why would you want to save it back as RAW? Since RAW will always need editing (you can't print a RAW image (yet?)), what difference does it make it you edit the shot (cropping/rotating) and then save it back having to edit it again anyway when you open it the next time? A RAW needs conversion to any other format for it to be useful, so doing a crop and rotation is a piece of cake. No need to do this in advance, right?
Doesn't saving the original RAW suffice?

Don't get me wrong, I'm not trying to sound harsh, I'm just wondering...  Smile

The reason I want to do elementary editing and then save it back as
raw is that raw is the ultimate format. If I for instance one year from
now have learnt a lot more about picture editing and want to reedit
all my pictures then I want to start with the original, ultimate quality
picture but I don't want to redo things like rotating and cropping.
That kind of editing I already know how to do and I don't expect
me to want to do that different one year from now.
In other words, I want to save ultimate quality pictures with all
basic editing done once and for all.

This is an interesting question. But I think it's probably better to keep the original RAW file, and re-edit that later on if you have learnt new techniques etc. Once you have applied sharpening and other techniques, the original data is already somewhat 'damaged' and so may not be suitable for re-editing later on.

Thanks for your views, hkg_clk, but you are missing my point.
The only editing I want to do with my raw pictures is rotating and
cropping, nothing else. After that I want to save them back in raw format.
My point beeing, if I in one year from now have learnt a lot more about
postprocessing raw pictures I don't want to have to redo rotating and
cropping which I don't expect to learn anything more about. I can imagine
going through my old pictures many times, trying different kind of editing
and then I don't want to have to redo the exact same rotating and
cropping each and every time.
But I'm beginning to believe there is no way to edit and save a CR2 picture.
I just downloaded a copy of Photoshop CS with the latest CR2 plugin.
Sure it let's you edit CR2 but it doesn't allow you to save it in that format.
So I guess I will have to switch to jpeg after all.

I'm with hkg_clk on this.
Don't touch your original file.
Save it, copy it and work on the copy.
You will use a lot of hard drive though!

Thanks Mick but rotating and cropping does not destroy any information
in the picture (just correcting it). And I will use less disk space if I can
save the raw:s after doing that than saving first the original raw and then
save a rotated and cropped jpg copy.

The alternative is to save as uncompressed TIFF (35+ mb vs. 6 mb RAW) losing the capability to do future RAW adjustments or as you say, shoot jpg and lose the adjustment options altogether.
I think the advantages with RAW by far outweighs the extra time to rotate and crop every time as you describe. Disk space isn't that expensive anymore either.

I agree, Staffan. Disk space really isn't the issue. The issue is that when
in one year from now I have 3000 pictures and want to reedit them all
from scratch (because I have learnt so much about raw editing  Wink/being sarcastic
I would like to not have to do the obvious rotating and cropping. I just
want to do that once and for all. Let's say I have learnt that raw pictures
all needs x percent brightening and x percent sharpening. I could program
that in Photoshop and let my computer do the work. If my originals are
saved without rotating and cropping I will first have to sit down and manually
go through 3000 pictures and rotate and crop all over again before I start
my Photoshop batch job. It could be so simple as that I want to regenerate
my pictures as 1600 pixels wide jpg:s instead of todays 1024 pixels wide.
That is a piece of cake with Photoshops batch option. But if all I have is
my uncropped, unrotated originals...thats a lot of manual work.

If you try to be consistent in how crooked you shoot your photos, you can make an action for correcting that too  Big grin

Ha, ha...I liked that one, Staffan. Guess I will have to put some
