Photoshop Exercise

First of all i created a new layer by dragging the thumbnail in the layers pallete. I started with the Master Chief since the background was all white I used the marquee tool to select some of the background then clicked on select>similar,then I selected the lasso and i held ALT got rid of the pixels that were on him.Next i choose Select>Inverse so that the Master Chief was selected then i clicked on the layer mask icon. then I opened the picture of the street and then Select>All,copy, then pasted it to the pic of the master chief.I dragged the thumbnail of master chief on top so he'd be in front.I had chang the size by going to Edit>Scale to make the background fit the whole picture and make the Master Chief smaller because he toke up the picture
