1) The room which was lit by natural light, and of course the lamp. Taken at Mohonk Mountain House, NY
2) The portrait of my lovely wife, who was lit from beneath by a living room lamp in the dark to get that eerie look (she is not eerie looking normally, but beautiful). A bit of masking and lowered the overall opacity to give it the slightly transparent look
3) Texture was added using a photo I took of a battered concrete basement floor, which I toned down quite a bit. I tried to keep it from being over done and let it be more on the subtle side.
I tried to not go too 'dark' with this piece, just wanted to keep the intention of the 'ghost' a bit mysterious by not going too obvious one direction or another.
