RAW query & Lightroom
-
Experts among us – I have a query.
I shoot in raw mode and have been for the last couple of months. I recently got the Sony A700 and still shoot raw. The images I get from the A700 are more vivid to the point where they’re over saturated. I import all raw files into Lightroom. So far so good?
My query – settings such as contrast, WB and settings available such as Vivid, Adobe RGB, Landscape, Portrait, etc – do they have an influence on the raw files? My understanding is that Lightroom uses the settings of the camera as a basis for creating a virtual copy of the raw file…but if I adjusted the camera for the previously mentioned settings would this effect the .arw file, or raw file or merely a setting for jpeg compression?
Your thoughts please.

No expert here Alan, but I’d be interested in the answer to this question
also. I’ve often wondered what effect, if any, these camera setting would
have on a RAW file…Rob.
Alan, as I understand it, Lightroom has a ‘default’ setting for all RAW files and it does not take the camera settings into account.
Could be wrong though!!
I asked this on another forum and realise the wording of the query may be confusing so I’ll recap:
My initial query is that if I set my camera to “Tungsten” in the WB settings on my camera for example, and I shoot raw does this raw file look different than if I’d set WB to “Cloudy” when I bring it in to any raw compatible application? Sorry for making the initial query over complicated. I’m aware of the capabilities of Lightroom – the reference may have diverted the meaning.

the white balance is independent of the raw file. but when you bring it into your raw converter the converter will read the settings you have set on the camera.
and then when you change the white balance it will change based on what you change it too, and have no ill effect on the image
Thanks Steve. I think your comment that the WB is independant but is read is what I was looking at. SO, I can alter settings and display the raw file with these settings applied as an image and it will have an effect, but the original raw file is not effected by the non ISO/Ap/SS type settings.
Cheers. I can sleep well now. :wink:

deff not by white balance.
I am not certain about the saturation type stuff, i think they are still independent but would be easy to test.
I was experimenting a while ago with my RAW files and using different settings on my camera.
What I noticed was that Lightroom was only using the WB settings for my pictures. When I was looking at the RAW pictures on my catalogue software (iMatch), it looks like the setting of the camera were applied, but I think it was only looking at the internal JPG of the RAW, as it was able to view my 40D pictures in an older version without an update.
So it seems that the camera settings a applied to the internal JPG of the RAW picture, but not to the actual RAW data.Whatever you do to a RAW file will have no lasting effect on the original file. You can see it as an exposed negative that hasn’t been developed yet. Once you develop your RAW file and convert it to TIF or JPEG the settings will take permanent effect. Not sure if that helps but it’s the best way I can explain it.
