Layering One Image Over Another

I then experimented overlaying an image of a building through the portrait above. I firstly opened the two images I would be working with.

I then dragged the background image over onto the portrait using the move tool.

I then selected the first layer in the layer menu bar, and changed the opacity on the sliding scale at the top of the box, to a lower percentage as to show the portrait through the building.

I experimented with this way of showing the two photos, by changing the opacity to a higher percentage.

I then changed the effect on the layer to see how it changed the opacity. From the box at the top of the layers box, where it usually says 'Normal' in a drop down box, I selected 'Overlay'.

This made the image much more vivid and the colours of the two photos stood out a lot more in comparison to each other. I experimented with changing the opacity of the layer now this effect was in place.
