I sometimes see fringes around subjects in my photos, especially along high-contrast edges. I'm using a Fujifilm HS20 bridge camera. What causes this, and what can I do while shooting or in post-processing to reduce it?

Some fringing is a result of overexposure. What happens is that the light shining on the sensor builds up a charge, and the charge sort of leaks to neighboring sensor elements. This produces a fringing around bright objects, for example, a picture of an egret standing in front of a dark background. The solution in this case is to lower the exposure.

Some fringing is the result of chromatic aberration in the lens used. In that case, the solutions are using a different lens or using software (such as Lightroom or Photoshop) that can correct chromatic aberration.

Fringing around high-contrast edges is usually caused by one of two things:

  1. Chromatic aberration (CA) from the lens. This is common, especially at wider apertures.
  2. Overexposure/blooming on the sensor, where very bright areas spill into neighboring pixels.

Ways to reduce it:

  • Avoid overexposure. If bright highlights are clipping, lower exposure.
  • Stop down if possible. Fringing is often worse wide open and improves at smaller apertures.
  • Shoot RAW. RAW converters often include chromatic aberration/fringing correction tools.
  • Correct in software. Programs like Lightroom or Photoshop can reduce CA effectively.
  • Use better optics if available. Lens quality affects fringing, though with a fixed-lens bridge camera your options are mainly camera settings and post-processing.

So with your HS20, the most practical steps are to expose a bit more carefully, avoid using the widest aperture when possible, and use RAW plus CA correction in post.
