The reason that 45 degree lighting is so important is that it’s the perfect angle to create modeling on the human form.

The term modeling refers to showing three dimensionality through the use of light.

When you have light coming from where the camera is, that three dimensionality is lost because shadows aren’t seen on the face.

Put the light off the camera and you get shadows, which gives you 3D, and 45 degrees is the perfect angle to maximize this effect.Camera

Geometry in Daily Life• Geometry is considered an important field of study because of its

applications in daily life. • For example, a sports car move in a circular path and it applies the

concepts of geometry. • Stairs are made in your homes inclined at 60o, with each stair

designed at 90 degrees. • A Simple cloth hanger has 2 x 30o angles + 1 x 120o angle = 180o

angle.• A ceiling fan has its 3 blades at 120o angles to make 360o while in

motion.• Any object when thrown at 45o angle, covers maximum distance.• In addition, geometrical shapes are also used by the artists. The most

interesting example is that nature speaks of geometry and you can see shapes in all things of nature.

What is so special …  •The Ridley frames are built with the longest head tubes in the industry.•The stem is sitting directly above the head tube, translation; comfort, stability, control.  •In addition to longer head tubes, Ridley has revolutionized frame geometry by introducing the first 1.5inch bottom headset.  •This enables maintaining light low weight on all their frames

Geometry in Daily Life We need not be lost anywhere in this great universe. We can

go to any place and come back to the place of origin. The location concept is a geometrical concept. Even a sailor   amid sea  and a pilot in the air  uses geometrical ideas to locate himself and where he is heading.

Designing our house, School, town planning,roads, bridges, surveying are the products of geometry.

Astronomy,Dynamics,Statics,Spacial movemnts  of Satellites and plannets ,  knwoledge of the sun ,stars,milky way and universe are the extended thought of the geometry.
