Any recommendations on uploading RAW?

Janceluch
Hi everybody,
Is there some guide on how to process the RAW file prior to upload (as additional format)?

My concerns are mostly about:
- does the RAW file have to look exactly the same as JPG version?
- or should it be "unprocessed" so the designer can process it on his own?
- or shall I do retouching (dust, imperfections etc...) and leave the rest on the designer?
- if I process the RAW file, do I submit the *.xmp file with *.cr2 file, or better convert it to *.dng... - or what is the usual way?
- and so on...

Any kind of advice or best practice is welcome. (or if there is a guide on this, just drop me a link here)
Thanx
and editing images :)...

It would be rare that a RAW would be the same as the JPG interruption. RAW is like a negative, the JPG is the print.

I was wondering the same because i crop the raw to come up with the "real" photo, which is the jpeg. I also perform noise reduction on the raw as well as using the stamp tool in Canon DPP before i convert to jpeg to finish off in GIMP. So i too have the same question. What do you want this RAW file to be ???? note to admin: thanks in advance for any reply

There is no processing of a RAW file. You get what you get. It is in essence a digital negative. Even if you modify it using Camera Raw or some other processing software, you can't save it as a RAW file.

actually that is not true. I just opened a RAw file in Canon DPP and cropped it, lightened it and added contrast and clicked "save" and it saved it as a .cr2 raw file with the same name. I opened it and inspected it and all the changes are permanent. I t is nondestructive in the sense that using "save as" does not modify the original but "convert" is used to make a jpg. "Save" saves as a new raw with .cr2 extension, same file name, so therefore it overwrites the original raw.

at least in Canon Digital Photo Professional. I've not used anything else so i don't know about other programs.

You can also process Raw files and save as such in Capture NX2.

Thanks guys for your replies - well, I still haven't seen the recommendations on uploading RAW to DT... :) But the discussion got kind of controversial, so let me clarify things about RAW files and saving them processed...

You can have processed RAW and JPG files look the same - if you are able to do all adjustments in Camera Raw software (like Adobe CR) than you can export JPG and save RAW adjustments after that - it will not directly rewrite the *.CR2 file (Canon RAW), but ACR will write a new file with all the adjustments (*.xmp file with same name as RAW file) and will store it in same folder. So now you have unprocessed RAW + all the adjustments in separate file - together those two files can be considered a processed RAW. (If you delete *.xmp file you loose all adjustments and RAW file is again unprocessed - same as it came out of camera...) (Some software like Lightroom do store the adjustments in their catalogue, so the xmp file is not created as separate file, but I am sure there is way of exporting it...)

The other method of saving processed RAW is saving it to DNG format (tested in ACR) - The DNG can hold all RAW data plus it embeds the adjustments in the same file - so saving into DNG leaves all RAW data available, plus saves your adjustments as well... so this way you have one adjusted RAW file. (that is what I did with my rusty texture shot, and the processed RAW file looks exactly same as JPG - but that was my only RAW file ever uploaded... )

So there definitely are ways of submitting processed RAW, even same-looking as JPG, but what is recommended - processed/unprocessed/semi-processed? - that is the question that was on my mind...

I assume if someone wants the RAW file they want to make their own adjustments - hence I just upload the RAW from the camera.

The only effect "Save", "Save As" or "Convert and Save" have on the Raw file is to insert a text list of the desired edits into the metadata section of the file. The original list written there by the camera (which DPP uses to set its defaults) is neither deleted nor overwritten and you can return to it at any time. The image data, an entirely separate section of the file, is in no way altered. I reiterate the RAW file itself is NOT changed by either command.

I am with Bradcalkins on that, if the buyers wants a RAW file, thats what he gets, an unprocessed RAW file exactly how I got it out of the camera.

Do RAW files sell well?

Frankly I think handing over your RAW file is not much different than selling the rights. Its like giving a duplicate negative to someone. At least with your processed jpeg, there is a limit to the manipulation and latitude someone has regarding your image. Just my own personal approach to that issue.
