Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to describe the relationship between exposure and output image lightness in digital cameras.
The grapheme Š, š is used in various contexts representing the sh sound like in the word show, usually denoting the voiceless postalveolar fricative /ʃ/ or similar voiceless retroflex fricative /ʂ/. In the International Phonetic Alphabet this sound is denoted with ʃ or ʂ, but the lowercase š is used in the Americanist phonetic notation, as well as in the Uralic Phonetic Alphabet.

In industrial design, preferred numbers are standard guidelines for choosing exact product dimensions within a given set of constraints. Product developers must choose numerous lengths, distances, diameters, volumes, and other characteristic quantities. While all of these choices are constrained by considerations of functionality, usability, compatibility, safety or cost, there usually remains considerable leeway in the exact choice for many dimensions.
When setting photoflash exposures, the guide number (GN) of photoflash devices is a measure photographers can use to calculate either the required f‑stop for any given flash-to-subject distance, or the required distance for any given f‑stop. To solve for either of these two variables, one merely divides a device's guide number by the other.
