ISO 12233 Test Chart

https://stephen-westin.com/misc/res-chart.html

Saved by uncleflo on January 6th, 2019.

In 2000, the International Standards Organization adopted ISO Standard 12233: Photography -- Electronic still-picture cameras - Resolution measurements for the measurement of camera resolution. This standard is protected by copyright, but the design of the associated test chart seems not to be protected; its description has been available on the Web in an Excel spreadsheet. I have semi-manually converted this to an Adobe Illustrator file which is displayed here. In 2014 and again in 2017, the ISO revised the standard and the chart below was replaced by several new ones. Those new charts are not available here. In principle, you should be able to print this chart and perform resolution tests on your camera. The reality isn't that simple; there are lots of subtleties having to do with focus distance, quality and contrast of your printer, evenness of illumination, surface reflections, etc.

Comma-separated values

https://en.wikipedia.org/wiki/Comma-separated_values

Saved by uncleflo on December 28th, 2017.

In computing, a comma-separated values (CSV) file stores tabular data (numbers and text) in plain text. Each line of the file is a data record. Each record consists of one or more fields, separated by commas. The use of the comma as a field separator is the source of the name for this file format. The CSV file format is not standardized. The basic idea of separating fields with a comma is clear, but that idea gets complicated when the field data may also contain commas or even embedded line-breaks. CSV implementations may not handle such field data, or they may use quotation marks to surround the field. Quotation does not solve everything: some fields may need embedded quotation marks, so a CSV implementation may include escape characters or escape sequences. In addition, the term "CSV" also denotes some closely related delimiter-separated formats that use different field delimiters. These include tab-separated values and space-separated values. A delimiter that is not present in the field data (such as tab) keeps the format parsing simple. These alternate delimiter-separated files are often even given a .csv extension despite the use of a non-comma field separator. This loose terminology can cause problems in data exchange. Many applications that accept CSV files have options to select the delimiter character and the quotation character.
