Real World Layers. Make a Photo Montage Using Layers.

Thank you for posting this.

I always have problems putting an image on top of a background layer - because they cover it.
So, another problem solved.

Quite often, I gave up, and went back to Elements 2.

Suggestion -

if you are planning on making all the additional photos the same size, drag them onto your project so they stack on top of each other, then choose the appropriate layers in the layer stack to activate them. Control T to resize all the layers at the same time. Move each into place after resizing.

Obviously, if you weren't planning on making the photos the same size, you could do each individually as the video shows.  But still, I like to do some resizing on all photos at the same time.  It's easier to handle smaller photos on your project.  You can always resize again.

BTW - Some versions of PSE do not require holding down the shift key to maintain proportion.  

You are right - I have "constrain proportions" check marked in my options when I use Control/Command T

Never noticed it because I never have a need to distort an item.

Always learning...
