Amazing Zoom Story

here is awesome zoom-out story. Actualy,  it’s better when you scroll it from end to begin:

A zoom lens is a mechanical assembly of lens elements with the ability to vary its focal length (and thus angle of view), as opposed to a fixed focal length (FFL) lens (see prime lens). They are commonly used with still, video, motion picture cameras, projectors, some binoculars, microscopes, telescopes, telescopic sights, and other optical instruments.

A true zoom lens, also called a parfocal lens, is one that maintains focus when its focal length changes. A lens that loses focus during zooming is more properly called a varifocal lens.

3 D MURAL

These realistic 3D murals are the creation of artist Eric Grohe who is from the United States. Some are lifelike enough that you will have to look very close to determine if they are real or not.

The following is an amazing series of murals by artist Eric Grohe. He takes a blank, sometimes derelict wall and brings it to life.

Eric researches, paints and designs each project from scratch while his wife Kathy, also an artist, serves as project manager.
