Converting a photograph from sRGB to Adobe RGB

Thanks very much for the input, all4 of you.

And Jim - yeah I really should be working in aRGB I realise. Call this a New Years Resolution - from now on...

So, in a nutshell - I shouldn't have to alter my monitor settings, but basically can convert in Photoshop then send to the client....

Moral of the story is work in the best colour space in the first place I reckon
