Hi Robert, i have shot for two years in cemeteries, and aside for the guardians who sometimes don't want you there, i have found it a great experience.
No, it isn't a morbid statement.
It is actually a great place to relax and to put things in a different perspective.
Yes , it has been done over and over again, but you know very well that if you take the same subject and 1000 photographers you will have 1000 diferent visions.
Go ahead and have fun.......if you can ...
