Raw and Jpeg B&W

Hi this is my first post and I would like to say a big hello to everyone.

Ok, so I am talking to this professional photographer that I have got to know last night, really nice guy, gives me tons if advice, and he starts talking about different picture quality settings.

He tells me that he shoots in Raw and Jpeg in B&W and that while the Jpegs are B&W the Raw files are in colour.
Only problem is he uses Canon and when we look through the menu on my D90 we can't find that particular setting. Now we're both flummoxed because he knows as much about Nikons as I do about Canons, which is to say nothing.
I realise that he has highest end cameras available with all the bells and whistles, but wondered if this setting is available on a D90, because I really would like to give it a go and see what happens.

So can you help me out folks?

Thanks.

G/Day and welcome...I should imagine if it's in your D90 it will be in your manual...

Not sure about the D90, but you can just convert the color RAW to B&W in post processing. Not sure why you would want the lower quality Jpeg anyway?

"He tells me that he shoots in Raw and Jpeg in B&W and that while the Jpegs are B&W the Raw files are in color."

That's the way it works with Nikon too. You just have to remember that the "raw" file has all the information collected by the sensor at time of shooting. The "jpeg" is only the raw file passed through the in-camera processing. So if you go for B&W, the jpeg will be in B&W but the raw will remain color.

Sometimes it saves post processing if you know for example that your shots will be going to a B&W newspaper for example.

Hope this helps.

Sorry for being a bit tardy in replying, been away in Cornwall for a week. The reason for shooting both is....That my friend recommended it. Guess you can get an idea of what an image will look like in B&W, they don't all take to it as we know, so it save processing it if it's a bummer. I ought to have realised that setting the Raw programme to B&W would have done the trick, thanks for the replies, will give it a go now.
