Here's a (relatively) quick exercise. Let's make it a challenge for any new folks and lurkers that say they "can't draw." Three shapes: a cone, a cube and a sphere. The idea is to draw them in a way that they show dimension and light/dark values. I'm using a 4B pencil which is rather soft so the lines show up. Use what you have. I just drew these; I'd recommend using real objects if you are just starting out - a small paper or ice cream cone, a block, and a small ball. 1. Rough Outline. Just that - draw the outline of the shapes you want to use. It doesn't have to be perfect or look like a mechanical drawing. The idea is to get some shapes on paper. 2. Highlights and defining the 3-D shape. We're photographers, so: I am placing my key light at camera right and lightly above the scene (over my right shoulder). The highlights for each of these shaped should look something like this. My toning is really darker than it should be on the cone, but you get the idea . 3. Shadows. The shadow from a single light source will have a shape something like that of the object. We also know that the shadow will point away from the light source, so it shoots out to rear-left. Mine are probably not exact but if you use real objects (a paper cone, a block, a small ball), you can get a better feel for it. 4. Final drawing, without the outline. I redrew this without the heavy outline. You can do as well with drawing the outline very lightly - just dark enough to see it. Again, the idea is to draw something or try something new. Let's see your results. Bonus exercise. I had to do this in art class. It helps you see how areas on and object relate when folded. 1. Draw a grid on a piece of paper. You don't have to measured and use a straight edge but the straighter the lines are and the more evenly spaced, the better. It is actually a little better if you make every third or fourth line a different color, like red or hot pink. 2. Crumple up the paper and draw that puppy. What you are looking for is how the lines appear when the paper is folded over.
