(digital photography)

1. what are filters? why would you use one?

2. what are color filters used for? what effects might different colors have?

Filters can help enhance a photograph and make the scene look better. You could use a filter to change the way the camera captures the image or how the light is effective. Some filters such as a polarized lense can reduce glare and changing the hues.

Colored filters can be used to change to color theme of an image. If you add a blue filter it can make things seem darker as well as having a "wintery" or "cold" feel to it. Red could make things seem brighter while also having a "Angry" or a "romantic" theme.

any school based questions?

i believe the answer is: a.  abstract forms were often used to represent human figures.

representing human figures in abstract forms is often used in the geometric period, not hellenistic  period.   during the hellenistic  period,   aesthetic value derived from creating arts which mimic the actual shape of a certain object or individuals.
