Film scans resolve detail about as well as the original film, up to the resolution of the scanner. There is no response to details finer than the resolution of the scanner, even if it's on the film and visible in optical prints. DPI is equal to 212 pixels per mm, or 0.045MP/mm

Use long addition to add your number columns from right to left, carrying as you normally do for long addition. With film, you get the same resolution at color transitions (green/magenta, for instance) as you get for light/dark transitions. This is all called Bayer Interpolation. With this, most digital cameras really only resolve about half their rated megapixel rating. For instance, a 10MP camera really only sees about as well as a theoretically perfect 5MP digital camera, or 5MP film scan. When laypeople compare film to digital, they aren't comparing film to digital. They are usually only comparing scans of film to digital. Proceed right to left. Multiply the ones digit of the bottom number to the next digit to the left in the top number. If you carried a digit, add it to the result and write the answer below the equals line. If you need to carry again, do so.

Calculating n th roots can be done using a similar method, with modifications to deal with n. While computing square roots entirely by hand is tedious. Estimating higher n th roots, even if using a calculator for intermediary steps, is significantly more tedious. For those with an understanding of series, refer here for a more mathematical algorithm for calculating n th roots. For a simpler, but less efficient method, continue to the following steps and example. To calculate n√ a:

Insert a decimal point in the product so it has the same number of decimal places equal to the total from step 1. Digital cameras never resolve their rated resolution. The only digital cameras that used to were those with Foveon sensors, but them Sigma started lying, too. Find the product of multiplicand and most significant digit (MSD) of 3-digit multiplier, and write down the product under the earlier product but the One’s place value of product should start from the Hundred’s place value of multiplicand. Multiplication Table is an useful table to remember to help you learn multiplication by 87. You should also practice the examples given because the best way to learn is by doing, not memorizing. Online Practice Film's sharpness decreases gradually as the pitch (spatial frequency of fineness of detail) increases.

Some common roots include the square root, where n = 2, and the cubed root, where n = 3. Calculating square roots and n th roots is fairly intensive. It requires estimation and trial and error. There exist more precise and efficient ways to calculate square roots, but below is a method that does not require a significant understanding of more complicated math concepts. To calculate √ a:Fuji Velvia 50 is rated to resolve 160 lines per millimeter. This is the finest level of detail it can resolve, at which point its MTF just about hits zero. This is one way film and digital look so different. Film records fine and coarse details naturally, while digital (and video) tend to record medium details more strongly than film, but have no response to the extremely fine details which film can record. But wait: each film pixel represents true R, G and B data, not the softer Bayer interpolated data from digital camera sensors. A single-chip 87 MP digital camera still couldn't see details as fine as a piece of 35mm film. Find the product of multiplicand and 2nd least significant digit of 3-digit multiplier, and write down the product under the earlier product but the One’s place value of product should start from the Ten’s place value of multiplicand. Arrange the 4-digit multiplicand and 3-digit multiplier for long multiplication method, multiply the multiplicand by Least Significant Digit (LSD) of multiplier and the product underneath to the line in the way that the Ones’s place value of multiplicand and One’s place value of product of LSD of multiplier and whole multiplicand should be vertically aligned in a straight line.

Often the finest medium details to which the digital camera is sensitive are boosted in contrast. This is called sharpening, and is how we get digital images to fool the eye into thinking they're sharp. To find the resulting product, find the sum of 3 individual product of multiplier and multiplicand. Each line will require one light and one dark pixel, or two pixels. Thus it will take about 320 pixels per millimeter to represent what's on Velvia 50.Therefore, at each pixel location in a digital camera's image, we don't have full R, G, and B data. We only get about half, which is why digital camera images at 100% won't look as good as good film scans at 100%, or lower resolution settings of your camera seen at 100%. Foveon chips see at full resolution, but the makers of those cameras lie about the resolution to keep up with other cameras. Most Foveon-chipped cameras (Sigma) multiply the real resolution by three! What Sigma sells as 14MP cameras are really only 5MP. Arrange the numbers one on top of the other and line up the place values in columns. The number with the most digits is usually placed on top as the multiplicand. Since the lie factor factor from digital cameras is about two, you'd need a digital camera of about 87 x 2 = 175 MP to see every last detail that makes onto film. Long multiplication means you're doing multiplication by hand. The traditional method, or Standard Algorithm, involves multiplying numbers and lining up results according to place value. These are the steps to do long multiplication by hand:
