the most commonly used way to shoot people walking is to track them using a tracking shot or crab shot, by doing this you not only see the characters but also the environment around them which helps the audience to know where they are and there surroundings. For example, the opening to Reservoir Dogs, introduces the characters of the film by using certain camera shots such as panning across the characters one by one and and tracking the group as the walking down the road.
Another affective method of shooting people walking is to stick to the 180-degree rule, the rule states that when film a scene such as this you always stick to a 180 degree radius of the group and to not 'cross the line', by doing this it makes it easier to follow what's going on and keeps the scene in more order. although this rule is affective, it can also work without it with scenes such as Kill Bill and the arrival of O-Ren Ishii into the club, although this scene uses all of the great techniques such as jump cuts with the music and panning of the group it does break the 180-dregree rule which shows that its not always needed in films.
To conclude, the way to shoot people walking is techniques and variety, without these it can get quite boring for the audience in a scene such as introducing a character and it can give the wrong impression of the character. variety is the key as it can make the scene much more interesting and entertaining to watch.
