Film speed is found from a plot of optical density vs. log of exposure for the film, known as the Dlog H curve or HurterDriffield curve. There typically are five regions in the curve: the base + fog, the toe, the linear region, the shoulder, and the overexposed region. For black-and-white negative film, the "speed point" m is the point on the curve where density exceeds the base + fog density by 0.1 when the negative is developed so that a point n where the log of exposure is 1.3 units greater than the exposure at point m has a density 0.8 greater than the density at point m. The exposure Hm, in lux-s, is that for point m when the specified contrast condition is satisfied. The ISO arithmetic speed is determined from:
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the point at which density is 0.1 less than the base + fog?
Ah, so.. unanswerable

As Universal's main product had always been low-budget film, it was one of the last major studios to have a contract with Technicolor. The studio did not make use of the three-strip Technicolor process until Arabian Nights (1942), starring Jon Hall and Maria Montez. The following year, Technicolor was also used in Universal's remake of their 1925 horror melodrama, Phantom of the Opera with Claude Rains and Nelson Eddy. With the success of their first two pictures, a regular schedule of high-budget, Technicolor films followed.

Ah, so.. unanswerable

In Lebanon, clashes between pro-Nasser factions and supporters of staunch Nasser opponent, then-President Camille Chamoun, culminated in civil strife by May. The former sought to unite with the UAR, while the latter sought Lebanon's continued independence. Nasser delegated oversight of the issue to Sarraj, who provided limited aid to Nasser's Lebanese supporters through money, light arms, and officer trainingshort of the large-scale support that Chamoun alleged. Nasser did not covet Lebanon, seeing it as a "special case", but sought to prevent Chamoun from a second presidential term.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was in charge of dealing with the Lebanon situation?
Ah, so..
Sarraj
