Understanding the Shadow Blister Effect and Bokeh

What phenomenon does the narrator attempt to replicate, which involves shadows appearing to grow towards each other?

• Shadow blister effect

• Magnetic shadow effect

• Shadow magnetism

• Surface tension illusion

What causes the shadow blister effect when two objects are at different distances from a light source?

• The distance of the objects from the light source

• The size of the objects

• The shape of the objects

• The objects' colors

How does a non-point light source like the sun affect outdoor shadows?

• It makes them sharper

• It makes them blurry

• It changes their color

• It makes them disappear

What is the source of bokeh in a blurry image?

• The size of the camera sensor

• The shape of the lens

• The spread of light rays from a point source

• The color of the light source

What happens to the bokeh when an object blocks the outermost light rays?

• It disappears completely

• It becomes sharper

• It shrinks from the opposite side

• It becomes more colorful

What visual effect occurs when the image sensor is too close to the lens?

• The image becomes sharper

• The image becomes blurry

• The image becomes darker

• The image becomes inverted

How does focusing a lens too far affect the appearance of objects?

• The near object becomes clearer

• The near object appears to shrink

• The far object appears to blister

• The far object becomes invisible

What happens to the bokeh when you focus a lens on the far side of a bright grid?

• The lines become sharper

• The lines become invisible

• The lines appear to attract

• The lines appear to repel

What is the effect of a dark background on overlapping blurry fingers?

• They appear to blister

• They appear to attract

• They appear to repel

• They appear to overlap normally

What is the main cause of the visual illusions discussed in the video?

• The geometry of light rays

• The color of the objects

• The speed of light

• The size of the objects
