A Little Photography Tip About Exposure & EV Compensation.

A Little Photography Tip About Exposure & EV Compensation.

If you think your photography is poor due to not having a good enough camera, you might be surprised to learn that if you take the time to try this basic tip, I guarantee your images will improve.

Light is the most important factor to consider when taking photographs. Learn to look at light in relation to exposure in terms of Shadows, Midtones & Highlights and your photography will improve regardless of what brand or model of camera you have.

Most DSLR cameras have a built in light meter with a scale that you can see in the viewfinder, if you think of your light meter as a Seesaw, the central marker is the balance point (The Midtones)

“What’s a midtone? Cameras basically measure the different tones of white and black and 18% Grey is in the middle of these tones.  Your camera uses these tones when it tries to make an exposure in relation to the tones within the scene.

However, if you take control of the exposure by putting your camera in to manual mode you will gain a better understanding of basic exposure, you may get it wrong at first, but the best way to learn about tones and light in relation to exposure is to play around and experiment.

OK, try this. Put your camera in Manual mode, now set your aperture to f5.6. Now look around for what you think might be a mid tone colour. Often green grass is very close to a mid tone, as is the colour post office red. Now by altering your shutter speed, get the hash marker on your cameras light meter so that it is in the middle of the scale. (Zeroing out the Meter) Take a picture and take a look at the image and look at the histogram. You should find that the exposure is well balanced, if the histogram clips to the far right or the far left, this indicates that the image is either over or under exposed.

As a general rule of thumb images with the majority of the colour white in the image need to be over exposed by two stops. Black is the reverse; you need to under expose by two stops. This is often referred to as EV compensation.

EV compensation can be added in most camera modes regardless of camera model or brand (check your manual of how to do this)

The point I am trying to raise is that if you learn to think about colours and their shades in relation to Shadows (very dark colours) and Highlights (very Bright colours) and how they can effect exposure, you will then understand how and why your camera meters a scene and can get it wrong. you can then take control of how the scene should be exposed by adding or subtracting EV and this will then help improve your images in terms of their exposure.
