All you need is a digital camera, a friend or two and a bit of patience to experience hours of photographic fun.
Creativity, rather than photoshop or CGI equipment, is all that is needed to create weird and wacky pictures.
You can create photo illusions by playing around with distance between your subjects. A common example is the Leaning Tower of Pisa shot – I'm sure we've all been subject to photos of our friends pushing, kicking and leaning against the building.
Distance will make your subjects look larger or smaller, depending on your needs. It may take awhile to set up and frame your shots but a perfectly timed result will make the whole thing worthwhile.
Angles are another good trick photography tool. This photograph was created by having the subject lie on the ground and then turning the camera on its side. You can create exciting photographs by using angles creatively.

According to the official website, sleeveface involves 'people holding vinyl record sleeves and covers in front of their face'. The idea is to extend the photograph from the cover into real life. You can see some examples on the website.
The latest Christmas photo craze is to recreate those old favourites from your childhood. You can keep it as simple or as elaborate as you like – some people stick to recreating the facial expressions or backgrounds, while others will recreate the outfits, subjects and poses. Ze Frank, the man responsible for the craze, has a good selection in his young me now gallery.
