NPF rule calculator French

A couple of years ago, Frédéric Michaud—a French photographer and amateur astronomer—devised the ultimate formula for the Astronomical Society of Le Havre. That formula is called the NPF Rule. Don't bother trying to decipher the acronym; the letters aren't initials, they're variables: N = aperture P = pixel pitch F = focal lengt The NPF Rule. A much more complicated and accurate rule for sharp stars is: (35 x aperture + 30 x pixel pitch) ÷ focal length = shutter speed in seconds. Pixel pitch = the camera sensor's.

The rule doesn't take into account pixel density, aperture, or diffraction; however, it is an easy formula to remember and calculate in your head in the field, so it is often used. If you're going to use this rule, I recommend subtracting 5 or 10 seconds from the result if you wish to print large from a high-resolution sensor If you are looking for a free calculator, there is a qDslrDashboard app, where you tap on the Rule 600 and then it will let you choose the sensor size, input the sensor width and height, aperture value, focal length, image width and height and then it will calculate the shutter speed for you according to the NPF rule GitHub - YSRKEN/npf-rule-calculator: 星野写真を撮る際の適切な露光時間を計算するツール. develop. 2 branches 1 tag.

The NPF Rule. The NPF rule is a much better rule for determining the slowest shutter speed you can get away with before you end up with star trails. That's the good news. The bad news is that it's a much more complicated computation. There is more good news though: There are plenty of apps that will do the calculation for you The NPF Rule has been added to the PhotoPills app to provide a real-time shutter speed recommendation. They call it Spot Stars which is essentially an NPF Rule calculator.
