not sure what you mean.

as to posting the picture, if it's an effect you want to accomplish, i wouldn't hit you with copyright infringement. it's within the forum, and the purpose of posting it was to ask advice...

if you can annotate on the picture what you are looking to replicate, we can try and give you the best solution. if you want to crop the picture to the area of interest it's fine by me.
