haamukuvia

Haamukuvia is a Finnish term that translates to "ghost images" or "phantom images." It is commonly used in the context of photography and digital imaging to describe unintentional visual artifacts that appear in an image. These artifacts are often faint or translucent and can resemble ghostly apparitions, hence the name.

The causes of haamukuvia can vary. In traditional photography, this might include light leaks during film exposure or developing processes, or double exposures where a single frame captures two distinct images. In digital photography, haamukuvia can arise from sensor noise, residual images from previous exposures on the sensor (sometimes called "image persistence" or "ghosting"), or artifacts introduced during image processing or compression.

These unwanted images can degrade the quality of a photograph and detract from its intended subject matter. Photographers and image editors often employ techniques to minimize or remove haamukuvia. This can involve careful handling of camera equipment, adjusting exposure settings, or using specialized software tools for digital image correction. Understanding the origin of haamukuvia is crucial for effective troubleshooting and achieving clear, artifact-free images.
