Sorry, i just re-read it myself and realise it doesn't make much sense!!lol
This is the effect im after.
I have some footage of a wedding and i want it too look like someone has taken a photo of the couple with the camera noise (already have that) and then a still image to appear looking like the photo has just been taken.
Then i want the footage to resume as normal.

I remember seeing it as a tutorial a while ago.
Hope that makes more sense if not sorry!!
