Canon ixus 970is Colour Swap & Colour Accent Feature

[dcb001]

Have recently purchased this camera and am trying to get to grips with some of the features. In shooting mode its possible to swap colours which is great & also to use the colour accent feature allowing you to highlight an object leaving it in colour and having the background in mono.
I would like to know if its possible to use these features after the photos have been taken. Can anyone help me here?
Have just come back from Cuba & got some great pics of old cars and would loveto use the colour accent feature.:confused:
Any help would be much appreciated.

It can't be applied after the fact in-camera; you'll have to use an image-processing program like PhotoShop Elements to do it in the computer.

Thanks Jon,
Was afraid this may be the case.
