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
