Nikon D90 users who take pho­tographs out­side of the F2.8 to F5.6 aper­ture range and with a fast shut­ter speed are the best pho­tog­ra­phers on Flickr. If they also post-process their images with any­thing but the manufacturer-supplied soft­ware, and license their images with Cre­ative Com­mons licenses, then they’re even bet­ter again.

Using a vari­a­tion of the Elo rat­ing sys­tem to objec­tively rate the qual­ity of pho­tographs, these are the results from ELOgrade’s cal­cu­la­tions look­ing at the qual­ity of pho­tographs com­pared across var­i­ous EXIF data cat­e­gories.

Of course, they went and spoilt the fun:

Please keep in mind that cor­re­la­tion does not imply cau­sa­tion as well as the sam­ple method­ol­ogy and size used by this report.

But I did like this com­ment, on dis­cov­er­ing the cor­re­la­tion between Cre­ative Com­mons licensed pho­tos and higher qual­ity ratings:

Maybe peo­ple who take the effort to make it eas­ier to share their work do tend to take bet­ter photos.
