Macro Photography.

Another lovely way to shoot great photos is to take them from a close-up view. This technique is also called Macro Photography. This type of photography is usually made with a DSLR and a special Macro-lens. These lenses can be really expensive, but photos like the ones you see of ants, can be really quite impressive.
Whenever I try and shoot some close-up photos I usually use a Tele-lens. Zoom in a bit, manual focus to the closest point you can get and walk towards the sub/object until it's in focus. This will usually get the same effect. This is also why most tele-lenses are called tele/macro, because they basically have both capabilities. A proper macro-lens will give the best results, of course, but it's a good way of trying this particular type of photography.

You don't always need the best and/or expensive equipment to get a good result. The photo below was made with the Canon EOS 1100D and the standard 18-55mm kit-lens:
