First and foremost, to be able to do this, we must have a minimum basic knowledge of Photoshop and management of layers (I used version CS4, but this can be done with any version of Photoshop ... .., unless they decide to install 1.0. ....).

1:-
First, choose the photo you want to be formed to zoom out (ie, the picture formed by Fotitos):

2:-
Cutting edge and adjusts the picture according to the final size you want with it to be:

3:-
Access the "filters", then "Pixelizar" and finally "Mosaic". This will transform the image in pixels (or "mosaic") of the size you want:

4:-
Once there, we assign the size that will have each of the mosaics of the image (the more tiles, more detail will be the final piece).
In this case, he assigned a size of 160x160 pixels per mosaic:

5:-
Maybe now it will become more arduous or embolante ...
In a new layer, we began to put all the photos that will shape the final image. To do so, each must put a picture next to each other completely stuck, and each must have the same size as the mosaics used in the previous step (in this case, 160x160 pixels):

6:-
This procedure must be done to complete the entire surface with photos.
Then, combine all Fotitos in a single layer (single image).
If the photos we have are not enough, what we can do is go repitiéndolas randomly so it does not feel too much.
In this case, the fourth of the photos of the image is repeated for disorderly manner that is not so obvious:

7:-
Now is when you apply the magic "Modes of Fusion "!!!!!
But .... ¿¿WHAT IS THIS?
The methods of fusion are a number of options that are placed at the top of the window "layers" and serve to achieve different transparencies between them.
Here it appears that we apply a method of melting the top layer (the layer containing all Fotitos).
By applying the method of merger "Overlay", the Photoshop it does is create a transparency in the midtones, meaning that the light and dark will remain intact.
With this, we get some of the photos in the top layer become transparent, allowing them to be able to see some of the content of the bottom layer (the layer containing the big picture pixelizada).
By combining these two layers, we get a single image that appears to be a baby formed by many babies ... .. :

8:-
Finally, we can adjust controls Brightness / Contrast and / or color balance to improve the final image:

And here you go: a picture made up of photos .... O.O:

(it seems that we broke the tuje, when in fact makes the Photoshop magic ...).
