[Background Effects to make a Background/Poster]

Yeah, I know it's paint.net

Anyway, i'm looking for how to do the background. Not blending images? Or can it be used to design the background too?

[Background Effects to make a Background/Poster]

I've been trying to search, but can't find any related topics for a while.

I'm really new to photoshop, so i need your help.

for example, a picture like this:

the patterns in the foreground.

Or, this picture:

Can someone teach me? Or guide me to a tutorial?

I haven't been able to find such tutorials or help.

I can be emailed at teresa.elizabethkoh@hotmail.com should there be any problem.

Thank You!
