Repeat Portraits

I am going to try and do my version of this image, i think it would be hard but its unique and interesting. I am going to try to do mine in the garden because there is more room and you can fit more repeats on it. 

To create this image you need to set your camera on a tripod so it wont move and ruin the image, you would set the timer and just take as many images as you wanted in different points in that space. Then you would upload it to photoshop and edit all the images together onto one of the pictures.
