If you have Photoshop CS3 you can automatically merge two different photographs to create a new one, with Photoshop doing all of the hard work for you.
I have two different Creative Commons licensed photos from Flickr. The first is After the Rain by Julie La France .
The second is St Paul's Kirche by Joachim S. Müller
First lets open Julie's photo. For this to work it needs to be on a transparent background. If you look in the layers panel you will see it is a Background layer at the moment. So double click the layer and click ok. This turns it into a normal layer with a transparent background. Then we want to enlarge the canvas so the second image can fit. Go to Image > Canvas Size and double the height. Then open the second image and drag it in. You should have something like this.
On the layer you have just pasted in lower the opacity by hitting four on the keyboard. You can now position your second image. Once you are done crop off the extra space using the crop tool.
Then bring the opacity back to 100% by hitting 0. Then in the layers palette hold shift and select both layers. Make sure the background to both is blue showing it is selected. Then go to Edit > Auto-Blend Layers. Photoshop does some magic and you have blended your images.
As a side note for anyone in the UK I can throughly recommend The Genius of Photography. The first episode was brilliant!

Super nice example of this feature! Those two photos worked well together. I’d be cool if there was a way to pull those sunbeams down just a bit further, I think that would tie them together a bit tighter.

Wow, cool effekt, I really like the result!
Would it also work with higher resolutions, to make a poster from it or so?

@Joachim S. Müller - Yes I’m pretty sure it will work with higher resolutions. There is nothing that means it shouldn’t!

I am having some trouble with this. When i click auto-blend it only shows the background and the image of the church disappears. Whats wrong?
