3D Transparent crystal ball tutorial.

Drawing a transparent crystal ball.  Tools Needed

• Pencil
• Clean eraser (For highlights)
• Smooth nylon brush (For blending)
• Digital camera with view finder
• Tripod/Mount
• Light Source

Steps

1. Focus a camera on the 3D shape you desire to draw. (Make sure the shapes complete view is within the surface you will be drawing it on.
2. Once you are happy with the angle at which the shape is placed while looking through the view finder, start to trace the outline of the image while looking through the view finder.

[In this video I decided to make my outline of the shape slightly bigger because the closer my pencil tip got to the object the tougher it was for me to see the line on the paper through the view finder.]            3. Work on the darkest areas first because they will be small and will not take up most of the                    object.      4. Next fill in your mid grays and heavy grays. The gray should become darker as it gets to the          object. (Keep it gray don't turn it black.)      5. Before you begin to blend the mid tones in the sphere blending the dark tones into the          mid tones.(This will leave pencil residue on the brush to make lighter tones easier to bring in          later.)      6. Start to blend the outer ring of the sphere, also rub your brush in curing motions in the          sphere to show some depth to the 3D object.      7. Once you have blended all of your shadowed areas so that they fade from darkest to white,           flip your pencil over and with the clean eraser and a firm grip draw in some solid white lines           following the curve of your shape.
         Make some minor touch ups and you should be able to look through the view finder again and see a 3D image. I hope this tutorial helped you if it did let me know. If you have any questions or comments please feel free to leave them.
