Other than the extra appendages, there's no post processing work. The Chain web and rig it's hung from was made by Mike from Deviant Designs and it easily supported the weight of both "Spider" and "Fly".
Gear and stuff:
K100D, manually set to custom WB and F8 at 1/125th and ISO200
Sigma 28-80 Asperical
