The camcorder was done 12 years ago in Adobe Illustrator 8 as an exercise in the use of the Gradient Mesh tool at the time when I was still learning Illustrator.
The binoculars were a freehand 'life' drawing exercise (my pair of binoculars set on the table) drawn in Photoshop. No tools or drawing aids were used, e.g. vector shapes like ellipses or Bezier lines.
#3 is the final drawing. #4 is #3 with a stroked fill.
