An optical effect is a special effect achieved by optical means, i.e. an optical printer, in contrast to effects created digitally using a computer.
Examples of optical effects are:
- Lap dissolves
- Slow motion
- Fast motion
- Matte work
- Freeze frames
However, it should be pointed out that, nowadays, many of what were formerly optical effects are now also achieved digitally using computers.« Back to Glossary Index
