Problem: For digital photo cameras ("digital still cameras"), an exposure index (EI) ratingcommonly called ISO settingis specified by the manufacturer such that the sRGB image files produced by the camera will have a lightness similar to what would be obtained with film of the same EI rating at the same exposure. The usual design is that the camera's parameters for interpreting the sensor data values into sRGB values are fixed, and a number of different EI choices are accommodated by varying the sensor's signal gain in the analog realm, prior to conversion to digital. Some camera designs provide at least some EI choices by adjusting the sensor's signal gain in the digital realm. A few camera designs also provide EI adjustment through a choice of lightness parameters for the interpretation of sensor data values into sRGB; this variation allows different tradeoffs between the range of highlights that can be captured and the amount of noise introduced into the shadow areas of the photo.
What is adjusted prior to conversion to analog?

Problem: In Central Africa, Ndembu warriors rub themselves with red paint during celebrations. Since their culture sees the color as a symbol of life and health, sick people are also painted with it. Like most Central African cultures, the Ndembu see red as ambivalent, better than black but not as good as white. In other parts of Africa, however, red is a color of mourning, representing death. Because red bears are associated with death in many parts of Africa, the Red Cross has changed its colors to green and white in parts of the continent.
What color do the Ndembu believe is better than red?

Answer: white

Problem: However, if the debt rescheduling causes losses on loans held by European banks, it weakens the private banking system, which then puts pressure on the central bank to come to the aid of those banks. Private-sector bond holders are an integral part of the public and private banking system. Another possible response is for wealthy member countries to guarantee or purchase the debt of countries that have defaulted or are likely to default. This alternative requires that the tax revenues and credit of the wealthy member countries be used to refinance the previous borrowing of the weaker member countries, and is politically controversial.
What would cause the private banking system to strengthen?
