It's strange - I feel more comfortable in disused churchs then real ones. What type of church is it? Could you get inspired by it's background?
There's a wonderful medieval one near my grandparents I want to do some neomedieval photos in :-) It's got quiet a weird background. The lady who paid for it to be built in memory of her husband was buried in it with his embalmed heart.
it's known as Sweetheart Abby.
