Indeed the "coloured version" was just the negative film which was scanned in the colour mode, cause I didn't succeed in scanning it in B&W..
I did nothing to the previous pic except this colour scan.

Thanks for your comment :)
Yes it's true...and in this idea that's Iwhy I like photoshop: because you take a pic...and you feel this pic has something but not just like that.. so you go to photpshop and you test different things...and often you're the first surprised about the result.. :)
