    I normally shoot RAW and convert through bridge to P shop

    Today I took some shots RAW + JPEG and was shocked at how vivid the JPEG image is next to the raw

    Is this colour space? or a setting I have missed on the camera?

    Or should I be boosting the colour in the conversion or in PS?

    Update
    Playing with the file I can saturate the image at +15-20 but this seems yet another step in processing.

    the reason the jpeg is more vivid is down to the camera processing the shot in accordance with the parameters selected. These may be user defined or automatic.

    RAW images capture what the camera sees and have no processing applied to them. It's normal for RAW images to look flatter than the jpeg for the above reason.
    Sure you can increase the colour in the RAW image - it'll give you something similar to the jpeg but it's a manual method. You can manually select how much or how little saturation to apply. The same applies to contrast, brightness sharpness etc. Jpeg reduces these options for you by making the adjustments when saving the image and deleting the info that's not required.

    As for colour space - not sure about that. Perhaps someone more knowledgeable will give some answers to that one.

    Makes sense, so I should be adding a saturation boost in PS in line with want I want from the image then

    if that's what you need from your image then yes.

    The problem is that adding saturation most often adds that irritating picture noise or grain, so it is best to use other approaches to improving colour such as the Channel Mixer, software filters or even changing the colour temperature.

    Amend the colour in the RAW converter itself - not within Ps although can further add saturation there.

    The RAW imnage should be edited to look its best within the raw converter.

    Adding saturation in a RAW converter shouldn't degrade the image. If it starts blocking pixels (making the pixels just solid colours) then the saturation being applied is too strong.

    If that's what you want. The beauty of photography is there isn't a single right answer for anything. There are no rules, there's just convention. I'm currently exploring photoshop too.

    the entire raw vs jpg concept is being missed here.

    If I had the time I would write about it... someone can provide a synoptis or a link ?

    Good ;) 'Raw vs Jpeg' is a topic like 'Film vs Digital' or 'Which Brand'... go down that route and you'll get a thread of at least 5 pages, about 5 posts of which constitute an actual debate. Sorry if I sound a bit pessimistic ;)

    The original post wasn't a raw v jpeg question - more a question about why a jpeg was more vivid than the raw image.

    That *was* the original question. And the answer was that the poster was looking at a processed image vs. an unprocessed (or incorrectly processed) one. I suspect the OP didn't have his RAW parms set correctly as (even though I'm a 99% JPEG shooter) you should always be able to meet or exceed an in-camera JPEG iimage using a RAW one.
