Removing Cars and People from Busy Streets

A pretty cool technique which allows you to remove all cars from a busy highway in one shot. 

There are a few great applications with this technique.

1) Removing people in a museum or at car shows for those who need to take a shot of something where people are always passing by.

2) For architectural photographers who want to take a shot of a building and want to remove all the cars and people coming in the way from across the street.

3) Any indoor photography in general, you can get really really creative.
