WebSoil profile was constituted by 1m-thick sublayers with a total depth 15 m in order to achieve maximum cut-off frequency criteria. In order to obtain the shear wave velocity of the profile, the small-strain shear modulus (Gmax) variation with depth of the soil were calculated with Equation 3 purposed by Seed & Idriss (1970). WebThe primary variables that affect depth of field are the focal length of the lens, the aperture setting, the subject or focus distance, and a subjective factor called the circle of confusion, abbreviated as the CoC. The circle of confusion describes the image resolution needed. There are additional considerations for close up (macro) photography.
