Am making a site to advertise Murder Mysteries - The Reading of The Will (Lord Felthorpe drowns in his bath)
Here's what I did.
Borrowed an arm and wet it. Placed the body next to a window. Natural light always good.
Made and printed out a Will
Opened up the image in Photoshop Raw
Set Clarity and Contrast to 100
Set Saturation to - 62
Filled the Layer with Black then selected the Eraser
Used the Eraser to reveal the layer beneath
A little more Clarity and blood stains using a variety of brushes and different reds.
And some text.
Took about ten minutes.
