The ISO standard for measuring resolution of “electronic still imaging”" cameras is 12233, available only from the International Standards Organization for only 116 Swiss Francs (about $US93 as of this writing) and under copyright protection. But the design of the 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.

A new article by Harvard Law School Professor Jill Lepore, published in The New Yorker, features insights from several past and present affiliates of the Edmond & Lily Safra Center for Ethics, including Mathias Risse (current Director, Program on the Ethics of Emerging Technologies), Lawrence Lessig (former Center Director and current Faculty Associate), and Josh Simons (former Graduate and Initiative Fellow).

I have tried to reproduce the ISO standard test chart using the official ISO data, but neither I nor Cornell University guarantees compliance with ISO 12233 or any other standard, nor do we take any responsibility for the quality of results based on this chart.

It seems that most folks, for example Imaging Resource, use this chart for visual assessment of resolution, but it's designed to do more. See those funny crooked “H”" shapes and squares? These provide data for computational analysis of resolution; tools are available at this site to perform this analysis; for more information, see this page. There is at least one company selling a low-cost (<$US100) kit for measuring resolution by means of this slanted-edge technique. For more info, I suggest a Google search or the Wikipedia article on optical resolution. Buying a real ISO 12233 chart The proper way to perform these tests is to order both the ISO standard and a properly-made test chart. The latter are available, for example, from Precision Optical Imaging in Rochester, New York. See the I3A site for worldwide sources. Expect to pay more than $US100 for such a chart. The alternative is to do it on the cheap: take the PDF file, print it in an appropriate size, download the code, and start testing. I think some people have posted raster images (e.g. JPEG files) of the chart on the Web; the outline description here should produce a better test chart, as it isn't limited to pixel-level resolution. DISCLAIMER I have tried to reproduce the ISO standard test chart using the official ISO data, but neither I nor Cornell University guarantees compliance with ISO 12233 or any other standard, nor do we take any responsibility for the quality of results based on this chart.

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.
