Template:ExposureTimeCategory/doc
This template transforms exposure time values extracted from the EXIF tags of an image into a format that matches the existing categories on Wikimedia Commons. The corresponding category is then added to the file page where this template is used.
The template automatically sets the following categories:
- Category:Exposure time ### sec (value dictated by input)
- Category:Exposure time category unavailable (if primary category is unavailable)
Usage
{{ExposureTimeCategory |1= }}
If a corresponding category is not (yet) available, files will additionally be placed in Category:Exposure time category unavailable.
Corrections performed by the template:
- Force decimal notation for values greater than 1.
- Round to one digit after the decimal mark.
- Try reducing the fraction. Only tests for division by the value of the numerator, by 2 and by 5 are performed, as by far the most common numerator in EXIF exposure time data apart from 1 is 10.
Division by zero is caught, no category is shown at all for values at or below 0.
