RAW to RAW.

[Lucato]

Hi guys, I's sorry for the dumb question, but is it possible to get a RAW file, adjust some stufss, let's suposse the EV, and save it again as a RAW with a new name?

Do you know any Freeware software or paid one that does that? If so, please post a name and/or a link.

Thanks in advance.

If you actually have a Canon EOS camera, then you also have Digital Photo Professional.

That's all it takes.

You cannot save a Raw as a raw so the adjustments are seen by *all* programs.

You can "save" adjustments you made in DPP so DPP sees them (writes settings into the file header), or you can "save" adjustments so Adobe software sees them (writes swttings into either XMP sidecar or fileheader if you use DNG).
These two aren't interchangable.

What is it you want to accomplish?

@apersson850
Yup, I got DPP, but it doesn't allow you to adjust a RAW file and save it again as a RAW.

"What is it you want to accomplish?"
René, lets suppose I forgot to take one shoot with diferent exposures. So, I'd like to ajust for example the exposure settings in 3 different levels and save each one as different new RAW file and get to open them later into other software that "layers" only RAW files to treat them as one image.

What you want to do is make your adjustments (in either DPP or ACR), and then save the resulting image as a TIFF (need to open in Photoshop if using ACR). Save the TIFF as something like IMG_12345_EV-1.tiff, then re-open the original RAW in DPP/ACR and repeat for the other levels.

Then just bring all the TIFFs into Photoshop and blend.

Egordon99, thanks for your Reply, but I don't want to do stuffs through Potoshop. As I have mentioned above with René, I'd like to ajust for example the exposure settings in 3 different levels and save each one as different new RAW file and get to open them later into other software that "layers" only RAW files to treat them as one image. So I can use this software resources and tools. ;0)

Doesn't make any difference. No application ever actually changes the RAW image data, only the appendixed conversion instuctions are changed when you "edit". And no application can read the instructions from another application (except LR - PSCS, which come from the same maker.)

[egordon99]

Not sure what software "layers only RAW files", but you should be able to just create multiple copies of the SAME RAW file but with NEW names (in command prompt type "copy IMG12345.CR2 IMG123456_a.CR2" and repeat for however many files you need.

But most folks do it using the method I described above.

[René Damkot]

You can also do that in DPP: "Save a copy"
Or, depending on how the other software handles the Raws, you might get away with ACR Version Control (http://www.completedigitalphotography.com/?p=430) for BridgeCS2.

Curious to what "software that "layers" only RAW files" that is...

[davidcrebelxt]

If OP is talking about doing that adjustment for HDR, or exposure blending, like in photomatix, you can always take that RAW and export it to 3 or more different .jpgs at desired EV, and blend those .jpgs... I think that's the typical method to accomplish that from a single RAW file.

You can do this with Lightroom. Make multiple virtual copies with different exposure settings then either open all of them as layers in Photoshop or merge to HDR in Photoshop.

[Colorblinded]

You can do multiple variants in Capture One as well, but nothing else I think will understand that because of how each program stores their data differently.

Perhaps it would be easier for the Op to understand the extreme difficulty of doing this if he/she understood that a RAW file isn't really an image to be manipulated like a jpeg or tiff file. Instead an image is created by whatever software is being used to convert the RAW file. The data in the RAW file isn't being changed to do this, it is just being used as input for an interpolation algorithm that actually creates the image from that data. The settings you specify to the conversion app just alters the algorithm, not the RAW data. Since the RAW data hasn't really been changed, there is no reason or object to re-save it. Somehow you would have to reverse engineer the created image back into raw data to do what he/she wants.
