Here is a question about this article: Upon exposure, the amount of light energy that reaches the film determines the effect upon the emulsion. If the brightness of the light is multiplied by a factor and the exposure of the film decreased by the same factor by varying the camera's shutter speed and aperture, so that the energy received is the same, the film will be developed to the same density. This rule is called reciprocity. The systems for determining the sensitivity for an emulsion are possible because reciprocity holds. In practice, reciprocity works reasonably well for normal photographic films for the range of exposures between 1/1000 second to 1/2 second. However, this relationship breaks down outside these limits, a phenomenon known as reciprocity failure.
What is the answer to this question: What determines the effect on the emulsion after exposure?
****
So... the amount of light energy that reaches the film


Here is a question about this article: Unemployment levels are low (31 individuals in 2013, compared to 50 in 2004 and 342 in 1998). Employment is dominated by the public sector, the number of government positions has fallen from 1,142 in 2006 to just over 800 in 2013. St Helena’s private sector employs approximately 45% of the employed labour force and is largely dominated by small and micro businesses with 218 private businesses employing 886 in 2004.
What is the answer to this question: How many private businesses employee people on Saint Helena?
****
So... 218


Here is a question about this article: After being lit at the birthplace of the Olympic Games in Olympia, Greece on March 24, the torch traveled to the Panathinaiko Stadium in Athens, and then to Beijing, arriving on March 31. From Beijing, the torch was following a route passing through six continents. The torch has visited cities along the Silk Road, symbolizing ancient links between China and the rest of the world. The relay also included an ascent with the flame to the top of Mount Everest on the border of Nepal and Tibet, China from the Chinese side, which was closed specially for the event.
What is the answer to this question: What is the name of the stadium in Greece were the torch was taken to?
****
So...
Panathinaiko Stadium
