Problem: Infrared cleaning is a technique used by some Motion picture film scanner, film scanners and flatbed scanners to reduce or remove the effect of dust and scratches upon the finished scan. It works by collecting an additional infrared channel from the scan at the same position and resolution as the three visible color channels (red, green, and blue). The infrared channel, in combination with the other channels, is used to detect the location of scratches and dust. Once located, those defects can be corrected by scaling or replaced by inpainting.
What can be corrected by scanning or scaling?

Problem: Following similar conflicts over modernism, the Southern Baptist Convention adhered to conservative theology as its official position. Two new Baptist groups were formed by moderate Southern Baptists who disagreed with the direction in which the Southern Baptist Convention was heading: the Alliance of Baptists in 1987 and the Cooperative Baptist Fellowship in 1991. Members of both groups originally identified as Southern Baptist, but over time the groups "became permanent new families of Baptists."
Conservative theology was the official position of what?

Problem: To create green sparks, fireworks use barium salts, such as barium chlorate, barium nitrate crystals, or barium chloride, also used for green fireplace logs. Copper salts typically burn blue, but cupric chloride (also known as "campfire blue") can also produce green flames. Green pyrotechnic flares can use a mix ratio 75:25 of boron and potassium nitrate. Smoke can be turned green by a mixture: solvent yellow 33, solvent green 3, lactose, magnesium carbonate plus sodium carbonate added to potassium chlorate.
What type of copper salts are used in fireworks?
