First, here’s an altered antique photo you can download and use in renders (the original.)
It’s not a large image so I enhanced the edges. Add it to a frame of your choice:
(from Frames by Fabiana, which I acquired when it was a Renderosity newsletter freebie.)
If you want to make your own creepy old photos, here’s what I did. I rendered smay’s Zombie M4/Genesis texture on the G2 Male base — edited to add: just the head, neck, and upper shoulder area — straight on, then rotated at +25/-25, +45/-45, and +90/-90, which covers the facial orientations of most old photos. Save each render as a transparent png image.
Copy the zombie image with the closest facial orientation of your target old photo, colorize the zombie to match (I usually recolor the zombie as well as the target photo), then resize/rotate the zombie image to roughly fit the face in the target photo.
I also use the mesh warp brush (Liquify in PS) to fine tune the fit. It doesn’t have to be perfect. When fitting the rendered zombie image to the old photo, change the Normal layer setting to around 50% so you can see where everything goes. Then change it back to 100% before you start playing around with layer settings.
Adjust layer settings to get the desired result, then erase everything but the face effect. I used various layer combinations of Normal (~20% to 30%), Soft Light (~50% to 80%) and Multiply (~10%), sometimes alone but more often as multiple duplicate layers. It depends on the original image and how strong you want the effect to look.
With the eyes, I sometimes used the Dodge Tool to make them whiter.
I did the same thing with a creepy V4 texture on the Genesis Child base and the Genesis baby, and also rendered the M4 skeleton’s head with all the rotations listed above to get a skull overlay instead of a zombie one.
Useful sources for old photos that are public domain/no known restrictions: Graphics Fairy — Old Photos — and Library of Congress Prints & Photographs Online Catalog. Most of the ones I used from LoC came from the Daguerreotype section.
