Image quaility

A shutter speed of 1/840 means the sensor was exposed for 0.0011904761904762 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 25 means the lightning conditions this photo was taken under were probably quite good, most likely in the outdoors during the day or with the help of a tripod. A low ISO like this usually translates into a good image quality, without "noise" or other kind distortions.
