Kuvavirheiden

Kuvavirheiden is a Finnish term that translates to "image errors" or "image defects." It refers to any undesirable alteration or imperfection present in a digital or analog image. These errors can manifest in various ways, affecting the visual quality and integrity of the photograph or graphic.

Common types of kuvavirheiden include noise, which appears as random speckles or graininess, often due to low light conditions or high ISO settings during capture. Pixilation is another prevalent issue, characterized by visible square blocks that become apparent when an image is enlarged beyond its resolution. Compression artifacts, such as banding or blockiness, can arise from aggressive image compression, particularly in formats like JPEG.

Other forms of kuvavirheiden might include color cast, where the overall color balance of the image is shifted, or chromatic aberration, which appears as colored fringes around high-contrast edges. Blurriness, whether from motion or improper focus, also falls under the umbrella of image errors. Dust or scratches on a physical negative or sensor can result in distinct marks on the final image. Understanding these potential kuvavirheiden is crucial for photographers and graphic designers aiming to produce high-quality visuals. Remediation often involves post-processing techniques to minimize or eliminate these defects.
