Relatively simple perspective question

[Allan Rahbek]

Hi, I just stumbled over this old tread and thought that I should try to make my point less brief by adding a practical example to show how the viewpoint, and angle of the view, affects the perspective in the final painting.
As you see, on the left illustration, the angle of view is about 75 degrees out of the full circle of 360 degrees. To project the correct drawing one would have to straiten out the curve before projecting the lines, but I cheated.

Hi there,

Nice thread!

If anybody wants, I can email the pages in a larger size.

All the best.

These are all from the book "Successful Drawing" by Andrew Loomis.

I've got many more pages about it.

One might ask: "Why should I study about it? I paint what I see!"
First of all, painting is 90 % drawing.
Second of all, most painters paint what they "think" they see and not what the actually see.
Last of all, sometimes you need to paint a posthumous portrait, and in that case, the model cannot sit for you, so you have to use these rules to make a better job. Sometimes the lighting in a photograph is horrible, but you liked the pose, so, you can change the values, lighting, etc, if you master perspective.

Hope it helps.
