 +====== Learning by example ======
 +
 +Aperture of Lens controls the art of blurry background and determines the highest shutter speed usable for a "​correct"​ explosure.

 +
 +====== Depth of Field ======
 +
 +DOF in a sentence: a distance range where object can be in sharp focus, at given lens and camera setting.
 +
 +What makes the depth of field, there are 3
 +  * aperture
 +  * focal length
 +  * film format size
 +
 +check this article in wiki [[http://​en.wikipedia.org/​wiki/​Depth_of_field#​DOF_vs._format_size|format size]]
 +
 +Conclusion, for same focal length, same aperture,
 +a large 135 filmback will provide about more than 5 times shallower dof than 1/​2.33"​ filmeback.
 +
 +  * So that is why compact digital camera even with f1.8 lens can not produce the same shallow dof on DSLR.
 +  * Roughly, a 1/​2.33"​ sensor [[http://​nikonrumors.com/​2011/​02/​08/​comparing-f1-8-compact-cameras-samsung-tl500-olympus-xz-1-and-nikon-coolpix-p300.aspx|digital compact with f1.8 lens]] produce about the same DOF as what DSLR camere produce at f6.3.
 +  * The only advantage of f1.8 lens on small compact digital camera is the large light capture, in result provide support of fast shutter speed for same amount of light exposure; combo result as fast camera action avoiding handshake motion blur.
 +
 +For focal length, at same aperture, such as f6.3, the larger the focal length, like 500mm, produces more shallow DOF than short focal length, like 50mm.
 +
 +While for close-up or macro lens, magnification rate plays more important role than focal length, larger magnification rate produce more shallow depth field. (so macro shot generally produce shallow DOF effect)
 +
 +Tilt-shift lens create shallower DOF by relatively shifting the film back off sharp center to corner blur area.
 +
 +As there is always [[http://​www.digicamhelp.com/​topics/​accessories/​lenses/​|apdater]] for everything, so does [[http://​videopia.org/​content/​view/​189/​231/​|shallow DOF adapter]].

 +
 +====== Human Eye ======
 +
 +  * 3 degree angle of clear view -> define target clear
 +  * Random eye movement -> direct viewer vision
 +  * Attraction priority (High>>​Low)
 +    - Bright spot attraction -> Darken corner
 +    - Value contrast spot attraction
 +    - Hue contrast spot attraction
 +    - Focus/Depth contrast spot
 +    - Angle
 +  * Object property

 +    - Texture
 +    - Object Movement
 +    - Positive / Negative Space
 +  * Object arrangement
