It is equivalent to 70-200mm on a 35mm camera, and covers from medium-telephoto range of natural angles to telephoto area with a compressed perspective effect.

The perspective effect is proportional to the lens's angle of view.

The perspective effects are not readily apparent in photographs, either, making viewing the gardens in person the only way of truly experiencing them.

Note also how the floor is tilted towards the square - a deliberate measure to enhance the perspective effect.

Most astronomers reject Arp's interpretation of the data since the anomalous observations could be explained by perspective effects.

Envelope Deformation is available via the Path Effects and provides a perspective effect.

The apparent movement in itself was a normal perspective effect; it was the rate of movement that was wrong.

More significantly, perspective effects come into play, particularly on rough or angled ground.

These types of lenses are often used to create forced perspective effects.

The work shows a scene that provides many deliberate examples of confused and misplaced perspective effects.
