Noise can be frustrating when it appears in your photos, especially when you don’t want it there! Whilst it can be a great way to achieve a funky, modern effect, it does take away from the sharpness and clarity of your photo. Increasing the ISO allows you to capture sharp pictures in low light situations by increasing the camera’s sensitivity, but it can also add unwanted digital noise to your picture. So, what are some ways of correcting noise and emilinating it from your photos?

To begin, it is important to know exactly what noise is and what to be looking out for. Dots, speckles and smudges of random color are generally what makes up digital noise on your photograph. It is most visible in places such as within skin tone or on a backdrop, where the tone should be even but becomes unstable. Digital noise can have a ‘grainy’ appearance; and this can often be appealing when attempting to achieve a unique style.

There are two great ways to eliminate digital noise - via your digital camera and on your computer. In order to reduce noise on your camera, use higher ISO values only when you require it - so the lower your ISO level, the less noise will appear in your photos. Many modern digital cameras have a noise-reduction mode and if so, ensure that it is switched on. Get to know your camera, what it likes to take and in what conditions.

To further eliminate noise, the next step can only be performed on your computer - so it’s time to get computer savvy! Transfer your photos to your computer and select your favourite image editor program. If you do not have one on your computer, have a look online and download a basic model. Programs such as PhotoShop and Paint Shop Pro often will have a noise-reduction filter that you can use to get rid of noise. Make sure you gain a good knowledge of the program that you are using, and understand how to use it effectively.

By this point, your images should have a very low level of noise apparent, if any!
