About this photo

This photo was taken by on 2009:09:13 14:04:18. The image has been post-processed using QuickTime 7.6.4, so it's possible that the shapes and/or colors have been modified, although these changes are usually minor and meant to improve the quality of the photo.

Image quaility

A shutter speed of 1/1600 means the sensor was exposed for 0.000625 seconds. This is a low enough value to guaranty that the image is probably sharp, even if captured without a tripod or if it has moving objects in it.

AN ISO of 400 means the lightning conditions when this photo was taken were probably not ideal. This image might have some "noise", particulary if zoomed in to 100%.
