Ok, so I took a random image on the hard drive, imported it into PS and worked on it in Camera Raw and then did some selective color back in PS. Yay...I have such a mental block about this. Unfortunately, I could not figure out how to do a collage in PS, so went back to Picasa for that part! Darn!
To do a collage in PS create a new page with width and height you want and add the photos side by side. You can leave space between and you can adjust the size of you photos and cut them down of you need. Takes a little work but doable. I usually use a template and add the photos to the template.Just look on line for free collage template for PS.
