Slow shutter speeds: how to achieve consistent exposures every time

Slow shutter speeds: how to get consistent exposures up and down the scale

How your histogram can help

Using your camera’s histogram display is the easiest way to judge when you need to manually over- or under-expose. Here’s how to use it…

How your histogram can help: under-exposed

1 Under-exposed

When an image is under-exposed, the histogram graph is bunched to the left, and there is a gap between the right-hand side of the graph and the end of the histogram display.

 

How your histogram can help: correctly exposed

2 Correctly exposed
The histogram for a correctly exposed image normally has a good distribution of tones right across the graph.

 

How your histogram can help: over-exposed

3 Over-exposed
In this over-exposed photograph you can see a gap between the left-hand side of the graph and the  start of the histogram display, and the whole graph is bunched over to the right.
