3D objects Within Photoshop there exists a class of objects known as 3D objects. Typically these are Fonts or Objects and each can be illuminated by a range of lighting sources and directions. Shadows are automatically part of this feature.
Cast Shadow Action
Limitations Such shadows are not “organic” that is: They do not soften with distance from the object They do not flow over other “apparent” surfaces They are not “masked” by foreground objects
Organic Shadows Creating organic shadows requires you to be Observant Artistic Have a working knowledge of Physics, Optics and Perspective Adept at using the “hand” tools in Photoshop, this is best achieved with a “tablet”
Organic Shadows 1 It is best to use an uncomplicated picture that has: Little in the way of “real” 3D topology Little in the way of “real” texture Little in the way of complex pattern or colouration A well defined light source
The Blue Dune
The Oryx Whether the object to be “shadowed” is already present in the image is somewhat irrelevant, but it is quicker is if is already a “floater”.
Blue Dune and Oryx
The Shadow Now need a Mask that roughly defines the object. If the object is approximately broadside to the light source AND approximately broadside to you (the viewer) then the Mask can be derived from the object. If not, then you have to use your artistic skills to draw a mask in Quickmask.
Selection Select the object with either: The Lasso (hand or magnetic) The Wand By Colour By Contrast Tidy the selection with Quickmask, but do not feather.
The Selection Save the Selection (as an Alpha Channel)
Distort the Selection/Mask Reload the selection and Distort
Distort the Selection/Mask Modify to account for light source vs viewpoint
Apply the Mask as a Layer Remove white area with magic wand and delete Re-transform and position to get exact fit.
Blur the shadow Use the radial blur tool and focus at the feet
Blur the shadow This creates the appropriate fall of in edge detail and contrast.
Gradate the shadow If necessary create a fall of in density with another Layer, the Gradient tool and a Lighten Blend
Order the Layer And retouch the interfaces
Blend Shadow layer
Mask or correct the Oryx Reload the Oryx Mask and Retouch or Feather if necessary, check alignment with Quickmask.
New Adjustment Layer Create and Adjustment Layer with this selection to apply to the Oryx.
Adjust Oryx Adjust the curves of the Oryx to suit the tone of light and the master image.
