F-number lengths. Therefore, reduced–depth-of-field effects will require smaller f-numbers when using small-format cameras than when using larger-format cameras. Image sharpness is related to f/number through two different optical effects: aberration, due to imperfect lens design, and diffraction which is due to the wave nature of light. The blur optimal f-stop varies with the lens design. For modern standard lenses having 6 or 7 elements, the sharpest image is often obtained around 5.6–8, while for older standard lenses having only 4 elements (Tessar formula) stopping to 11 will give the sharpest image. The larger number of elements in modern lenses allow the
The Opposite Six a pun, grew out of their prior moniker. The band went to local media personality, Bill Rase's primitive studio to record a single featuring the self-pened "I'll Be Gone," written by guitarist Don Wright which was a ragged Kinks and Rolling Stones-influenced number featuring Ed Dunk's nasal vocal and was backed with "Why Did You Lie?" The record was released on the Spectre label in January, 1966. The song became a big hit locally. After graduating from high school, the Opposite Six broke up. Don Wright later cut another version of "Why Did You Lie?" backed with "Draft Dodger Blues"
