Control Image Log For Free

What is Log. To put it simply, Logarithmic footage, generally known as Log, is flat footage that contains more details of the scene it's baking into the image. This kind of footage is not intended to be used without editing so it needs further alterations to be used as the final footage.

The logarithmic operator is a simple point processor where the mapping function is a logarithmic curve. In other words, each pixel value is replaced with its logarithm. Most implementations take either the natural logarithm or the base 10 logarithm.

There are two main reasons to use logarithmic scales in charts and graphs. The first is to respond to skewness towards large values; i.e., cases in which one or a few points are much larger than the bulk of the data. The second is to show percent change or multiplicative factors.

From a security point of view, the purpose of a log is to act as a red flag when something bad is happening. Reviewing logs regularly could help identify malicious attacks on your system. Given the large of amount of log data generated by systems, it is impractical to review all of these logs manually each day.

Raw is not Log because Log is in a video format, and raw is not video. Raw data has no video processing baked in and has to be converted into video for viewing. Log is video and has things like white balance baked into it.

The Definition of a Logarithm Just as subtraction is the inverse operation of addition, and taking a square root is the inverse operation of squaring, exponentiation and logarithms are inverse operations. Finding an antilog is the inverse operation of finding a log, so is another name for exponentiation.

Logarithmic functions on cameras were designed to capture the maximum dynamic range that the sensor was capable of, as well as colour information, and cramming it all into a smaller 'container' without having to record raw. Log works best if it is recorded with 10-bit colour precision.
