Why Photos Have Noise and How to Fix It: Simple Photographer Tips

Why Do Photos Have Noise and What Can You Do About It?

Noise in photos is like static on the radio—small, annoying imperfections. If your pictures sometimes appear grainy or “spotty, ” especially in low light, let’s figure out why it happens and how to fix it.


Why Does Noise Happen?

  1. Low Light Struggles:
    When there isn’t enough light, the camera compensates by increasing ISO (light sensitivity). The higher the ISO, the more noise you’ll see.
  2. Sensor Size Matters:
    Bigger cameras like DSLRs or mirrorless ones handle noise better than smaller ones like compact cameras or smartphones because their sensors capture more light.
  3. Long Exposures:
    If you’re taking long-exposure shots, the camera can heat up, introducing noise into the image.

How to Keep Noise Under Control

  1. Lower ISO:
    Use the lowest ISO possible. A tripod or stable surface can help compensate for slower shutter speeds.
  2. Get More Light:
    A fast lens (with an aperture of f/1.8 or wider) lets in more light, allowing you to shoot with lower ISO settings.
  3. Add Light Sources:
    Even a small light source like a flashlight or desk lamp can improve your photo.
  4. Shoot in RAW:
    RAW format retains more detail and makes it easier to reduce noise during editing.

What If Noise Is Already There?

  1. Editing Tools:
    • Lightroom and Photoshop have noise reduction settings that work wonders.
    • Specialized software like Topaz DeNoise AI can take it even further.
  2. Don’t Overdo It:
    Removing too much noise can make your photo look overly smooth and unnatural.

Should You Always Remove Noise?

Not necessarily! Sometimes noise adds character. For example, a little grain in black-and-white photos can enhance their charm and atmosphere. But if the noise distracts from the main subject, it’s best to reduce it.
