Camera

This was an excellent use of camouflage that was shown in Jack Black's "Be Kind Rewind movie. The invisibility effect was realized using painted garments. The effect probably works very well if it is viewed from the right direction; it was very well received by the audience as people laughed during this scene. The movie also features a lot of optical illusions that the actors use to portrait some of the most famous scenes in classic movies.

New technologies in camouflage are being actively researched and developed in many parts of the world; this University of Tokyo-Japan video shows something they coined as optical quasi-invisibility cloak in which the background image is cropped and projected on a reflective surface; this projection is very dependent on the angle from which the camouflage is viewed as in the case of the "Be kind rewind movie".

Some optical illusions take advantage of the fact that cameras and pictures as we know them are 2D representations of a 3D world. Creating this type of optical illusions requires placing yourself at the right angle to break the concept of scale and perspective.

Getting the right camera shot requires some preparation and time as well as good light conditions; to get objects close and far in focus and as sharp as possible you must maximize the depth of field. To achieve this, it is necessary to use the smallest aperture which corresponds to the highest f/ value on your camera. It is also recommended to focus the farthest object. The following pictures are beautiful achievements of this optical illusion:

This image by Looking Glass is a beautiful example of the illusion of scale in which this boy seems to be putting a finger on the top of a very small's person head.

Light is one of the most common but yet puzzling phenomena. It is both energy in the form of electromagnetic radiation and mass composed of elementary particles called photons. Before humans and animals and the earth there was light, yet, after so many years on this earth we can't still figure it out completely.
