My daughter asked me if I wanted to do a Halloween shot, I couldn't get my camera gear out fast enough.
Very simple concept, took one shot of my daughter then another shot of a roll of pork for the neck and a knife covered in fake blood.
Just combined the two shots in photoshop.
Poured some water over the blood to get the blood flow towards the plug hole.
Lit with one light, a Godox AD200 with dome diffuser pointing towards the ceiling.
My Nikon D750 and Tamron 24-70 was balanced on the lip of the bath with a manfrotto tripod.
Had to photoshop out the tripod legs and add some extra hair as well.
I copied and pasted the right hand side of the image to the left side to add symmetry.
No children were hurt in the making of this image, oh errmmm except my daughter who has a sore throat and isn't saying much :-)
The only strange thing is water above the hair :). Unless it's just weirdly shaped bathtub.
