RAW+JPG - is it different?

Will both RAW files have the same information regardless of selecting RAW+JPG or just RAW in the camera menu? I'm thinking that having the RAW+JPG somehow effects my RAW converted file to always look like the attached JGP. Im thinking it should not but I read a post that hinted otherwise.

Can you understand that....?

I think your question is this. Parameters affect the JPEG image. Do those parameters affect the RAW image part of the RAW+JPEG file?

No. The parameter data is still carried along with the RAW file (as EXIF) even though the parameters are not affecting the actual image.

Where this gets more complicated is that different RAW converters operate differently. Some will read the parameters data and offer that mix up in the conversion as a default conversion setting. Other programs will offer up something completely different as a default conversion setting. In general, you can override all defaults and make it convert in whatever style you choose, but the programs operate differently.

Your question makes no sense at all to me. Go read the CS2 version of this book (external link), if it doesn't answer your question come back and ask it again.

Well maybe your explaination applies to me. I have another post that is complaining about when i convert my RAW file it always looks like its companion JPG file (even though the RAW converter software shows it looking different)

Its a little confusing. If you take the raw image, don't make any manipulations but use the default parameter set and convert it, I think it should obviously look like its jpeg counterpart.

It is very much possible that what you see on the monitor may depend on the software rendering it, which should explain why it looks different on the RAW converter.

Ah no, people here all like helping people out, perhaps rephrase your question, that book would probably help you though.
