Editing Low-Light Photos: Brightening Without Making Them Grainy

Dim restaurants, evening events and indoor parties are some of the hardest places to take good photos. The camera struggles to gather enough light, and the results are dark, blurry or grainy. Editing can help, but it has limits.

Why low-light photos look bad

• Not enough light reaches the camera sensor, so the picture is dark.
• Noise appears as grainy speckles, because the camera amplifies weak signals to compensate.
• Blur from slow exposures, since the camera keeps the shutter open longer, and any movement smears the picture.

What editing can do

Brightening a dark photo is straightforward, but it also brightens the noise. Balance is key.

1. Raise brightness moderately, rather than all the way.
2. Lift shadows to reveal detail in dark areas.
3. Recover highlights if lights, such as lamps and candles, have blown out.
4. Add contrast to bring back depth, since brightening can make a picture look flat.
5. Correct colour, since dim indoor lighting is often very yellow.

Dealing with noise

Noise reduction smooths out grain, but too much removes detail and gives a waxy, plastic look on skin. Apply it lightly. A little grain is more natural than smooth mush.

Black and white for noisy photos

Converting a grainy photo to black and white can make noise look like film grain and often looks much better than colour noise.

Colour noise versus luminance noise

Colour noise appears as red and green speckles, and luminance noise as grain. Colour noise is usually more distracting, and can often be reduced without damaging detail.

Shooting tips for low light

• Hold steady with two hands, elbows in, or brace against a wall or table.
• Use night mode if your phone has one, and hold still for the full exposure.
• Find a light source, such as a window or a lamp, and move the subject towards it.
• Avoid digital zoom, which magnifies noise.
• Tap to focus on the subject, and adjust exposure before shooting.
• Take several shots, since some will be sharper than others.

Flash

The built-in flash produces harsh light and red-eye. If you use it, keep the subject close and consider softening the result in editing.

Setting expectations

An editor can improve a low-light photo, but it can't add detail that was never recorded. A well-shot low-light photo will always beat a badly shot photo that has been rescued.

Practice

Take the same dim scene with and without night mode, and compare the results before and after editing.
