Like many before you, you have posted here wanting to achieve a specific look or technique in Photoshop, but you say you have only used the program once. Until you learn the basic tools and techniques, there is no way anyone here can spell it out for you because you won't have a clue what they are talking about.
Photoshop is one of the heavy lifting, deep and wide programs for digital editing. I've been using it for years and still learn something new every day. I don't know that anyone can fully master it. Even the pros that write the books and do the video tutorials have aspects of the program that they excel in and others areas in which they still feel they have much room to learn. Team that with the fact that
PS is ever changing, and new third party tools come on the market all the time to expand our learning potential.
No one here has the time to tutor you on the basic functions. You have to do it on your own. Take some classes, read books, watch videos, surf the net for tutorials. Browse through the
PS manual, get an idea of the various tool functions, learn the vocabulary so that when you follow a tutorial (here in
RTP or other sources) you have a basic knowledge of what people are talking about. Otherwise it is a waste of our time to try to explain a technique and you will get very frustrated.
I've never seen the "Dove" stuff, so I have no idea of where you are trying to go with a graphic. Sorry.
