| | Photography camera is mainly about lens: video on [[http://www.youtube.com/watch?v=hk5IMmEDWH4|"Good Camera" or "Good Lens"]] is more important? |
| | ====== 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]]. |

| | ====== Exposure and Light Metering ====== |
| | |
| | * THE ULTIMATE EXPOSURE COMPUTER |
| | * ref: http://www.fredparker.com/ultexp1.htm |
| | |
| | ====== 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 |
| | - Lines or Shapes |
| | - Texture |
| | - Object Movement |
| | - Positive / Negative Space |
| | * Object arrangement |
| | - Center align -> no movement, stable |
| | * Lens |
| | * Formula with factors |
