The ISO standard ISO 12232:2006 gives digital still camera manufacturers a choice of five different techniques for determining the exposure index rating at each sensitivity setting provided by a particular camera model. Three of the techniques in ISO 12232:2006 are carried over from the 1998 version of the standard, while two new techniques allowing for measurement of JPEG output files are introduced from CIPA DC-004. Depending on the technique selected, the exposure index rating can depend on the sensor sensitivity, the sensor noise, and the appearance of the resulting image. The standard specifies the measurement of light sensitivity of the entire digital camera system and not of individual components such as digital sensors, although Kodak has reported using a variation to characterize the sensitivity of two of their sensors in 2001.
What techniques did CIPA DC-004 provide?
****
The answer: two new techniques allowing for measurement of JPEG output files

The meaning and origin of many archaic festivals baffled even Rome's intellectual elite, but the more obscure they were, the greater the opportunity for reinvention and reinterpretation a fact lost neither on Augustus in his program of religious reform, which often cloaked autocratic innovation, nor on his only rival as mythmaker of the era, Ovid. In his Fasti, a long-form poem covering Roman holidays from January to June, Ovid presents a unique look at Roman antiquarian lore, popular customs, and religious practice that is by turns imaginative, entertaining, high-minded, and scurrilous; not a priestly account, despite the speaker's pose as a vates or inspired poet-prophet, but a work of description, imagination and poetic etymology that reflects the broad humor and burlesque spirit of such venerable festivals as the Saturnalia, Consualia, and feast of Anna Perenna on the Ides of March, where Ovid treats the assassination of the newly deified Julius Caesar as utterly incidental to the festivities among the Roman people. But official calendars preserved from different times and places also show a flexibility in omitting or expanding events, indicating that there was no single static and authoritative calendar of required observances. In the later Empire under Christian rule, the new Christian festivals were incorporated into the existing framework of the Roman calendar, alongside at least some of the traditional festivals.
What did obscure festivals offer Romans the opportunity to do?
****
The answer: reinterpretation

At the beginning of the Han dynasty, every male commoner aged twenty-three was liable for conscription into the military. The minimum age for the military draft was reduced to twenty after Emperor Zhao's (r. 8774 BC) reign. Conscripted soldiers underwent one year of training and one year of service as non-professional soldiers. The year of training was served in one of three branches of the armed forces: infantry, cavalry or navy. The year of active service was served either on the frontier, in a king's court or under the Minister of the Guards in the capital. A small professional (paid) standing army was stationed near the capital.
At what age could a male common expect to be conscripted into the military?
****
The answer: twenty-three

Another occasionally used criterion for discriminating dialects from languages is that of linguistic authority, a more sociolinguistic notion. According to this definition, two varieties are considered dialects of the same language if (under at least some circumstances) they would defer to the same authority regarding some questions about their language. For instance, to learn the name of a new invention, or an obscure foreign species of plant, speakers of Bavarian German and East Franconian German might each consult a German dictionary or ask a German-speaking expert in the subject. By way of contrast, although Yiddish is classified by linguists as a language in the "Middle High German" group of languages, a Yiddish speaker would not consult a German dictionary to determine the word to use in such a case.
Of what group of languages is Yiddish a member?
****
The answer:
Middle High German
