Pretty woman and old ugly witch in one picture

Couple of weeks ago, I attended some marketing lecture and the lecturer show us some picture.

What do you see in the following picture?

First time, people told that there is a pretty woman.

However, when you see a little bit below, the woman in the picture will look as a ugly witch.

The lecturer told us that you can see a different person by each point of view.

If you have a positive view, it will look as a pretty woman and in a negative view, it looks like an ugly woman.

What do you see there?

By the way, I found one more point.

The same picture looks different by where you see.

When you look at a little bit upper right from the middle, you see a pretty girl.

But, there is a ugly old witch when you look at below the middle (the necklace around the neck)

Is it very interesting?

I hope that it helps your idea and life
