Grapes, cherrys and the eyeball
The cherry also has similar qualities to the grape though without the transparency.
Fig 1 Fig 2 Fig 3 Fig 4
See above .... the dark (Fig 1), the frosting (Fig 2), the red (Fig 3) and the highlight (Fig 4).
Then ... below they are assembled with a few 'realistic' toutches. Most of the frosting is
removed and the exposed shiny bright red skin makes the 'highlight' sharper. There is no
'transparency' in the cherry. You will no doubt remember the lesson on the 'pearl' which was an
object with similar non-transparency.With the grape and the pearl (or cherry) we have created the two spheres that
together will allow us to understand, paint and add the sparkle we want to the the
human eye.To see how this is achieved you must go to the next page.
