Photoshop - Concept Board

This is my concept board.

First, I found some images on internet, using google searching tool, typed the images' names, then I used the advanced searching list on the left of the website, I chose the colors and sizes of my images.And I also used the images taken by myself. 

Secondly, I opened my images in Photoshop, using the polygonal  lasso tool to select the part of the image which I want to add to my concept board, and then used the move tool to move these parts to my concept board.  If I don't want to select , I can click the"reselect"button.

Then I clicked "edit">"transform">"scale", to adjust my images. 

 

Once I was satisfied with my images' positions, I used many tools to make different feelings of my board. I used the type tool to add the name of my board:"mechanic"and "organic".

Once I settled all my images, they became a new layer, and if I want to change one of my images' effect, I clicked the layer which one I want to change, and then clicked some effect options, such as  "blending mood","fill","feather"and "opacity".

 

And finally I made my concept board.
