Compare the photos to maps of the constellations, e.g. Out of this World and of course, your starfinder.

You will find out that the hints help you more than the actual photos.  This is not the fault of the photos (they're more accurate than the starfinder).  Also, the starfinder is limited in its ability to represent stars, e.g. it cannot show subtle graduations in brightness.  The photos are closer to what you actually see in the sky.  However, since I usually do 20 second exposures, they actually show more stars than we see with the naked eye (case in point is Cassiopeia which is lost in a photo because the Milky Way is recorded brighter than it appears).

These are the constellations:

Hercules, Cassiopeia, Corvus, Andromeda, Leo
Scorpius, Ursa Minor, Serpens Caput, Virgo, Ophiuchus
Libra, Orion, Pegasus, Perseus, Aquila & Delphinus
Cygnus, Cepheus, Canis Major & Minor, Bootes & Corona Borealis
