'Shooting from the hip' is a term used in street photography. The camera is
usually held at hip/chest height, this is a discreet way of taking
photographs. The disadvantages are it is difficult to compose the shot.
Obviously if the camera is placed to the eye, the composition of the image
would be much better. But in doing that, it doesn't make you discreet any
more as it's obvious you are taking a photograph. However, this can also
play to your advantage especially in tourist areas.
As long as you blend into the crowd, and not stick out like a sore thumb
with a telephoto lens attached to your camera! Whilst tourists are snapping
away, you can compose the image naturally. Holding your camera to your
eye as if you are taking general holiday photos just like everyone around
you.
