Painted Sphere

LEARNING TARGETS:

»  I can paint a realistic sphere in Adobe Photoshop.

»  I can blend color SMOOTHLY to show a spheres volume in Adobe Photoshop.

» I can identify the important components of light & shadow : Umbra, Penumbra, Specular Highlight, Reflected Light, Core Shadow, Ambient Shadow, and Mid-Tone Value.

»  I can identify the direction of the light source and accurately paint the shadow in Adobe Photoshop.

EXPECTATIONS:

»  You are to repaint this reference image using Photoshop in a 5 X 7 document (@ 300 DPI) including the background, shadows, & specular highlight.

» All layers must be labels; post a screen shot of layers in blog.

 *Document in blog.

NEW VOCAB

Umbra – (Latin for "shadow") The area completely obscured by object or the “Hard” shadows Penumbra – The area partially obscured by object or the “Soft” shadows Core Shadow - Specular Highlight - This is a reflection from a light source and is the bright spot of light that appears on the surface of a 3d object. The smaller the highlight the shinier the surface, the larger the highlight the more the surface defuses the light. Reflected Light – Is a faint light reflected or bounced back on the object from the surfaces surrounding it. Mid-Tone – The tonal value mid-way between the highlight and shadow. Sometimes referred to as halftone. Value – The gradation of tone from light to dark or of color luminosity

• Using the Elliptical Marque Tool, draw a circle while holding down the {SHIFT} key. *Hold shift maintains an equidistant aspect ratio. Scale it and place it appropriately.
• Create and label 6 new layers and use them accordingly.
  • Reference
  • Specular Highlight
  • Ground Reflection
  • Color
  • Key Shadow
  • Ambient Shadow
• Paint the base color/value giving the sphere volume in the Color layer. *Use a layer mask.
  • Fill in mid-tone color first
  • Paint the reflected color in the Color layer.
