kuvanlaadunheikentymisiä

kuvanlaadunheikennys is a Finnish term that translates to "image quality degradation." It refers to the process by which the visual quality of an image deteriorates over time or through various manipulations. This can occur due to a number of factors, including the physical aging of the image medium, such as paper or photographic film, leading to fading, discoloration, or damage from environmental factors like light, humidity, and pollution.

Digital images can also suffer from kuvanlaadunheikennys. Compression algorithms, especially lossy ones like JPEG, reduce file size by discarding image data, which can result in artifacts, blurriness, and a loss of detail. Repeated editing and saving of digital images, particularly with lossy formats, can compound this degradation. Furthermore, display technologies themselves can influence perceived image quality, with factors like pixel density, color accuracy, and screen calibration playing a role. The capture process itself can also introduce degradation if the camera settings, lens quality, or lighting conditions are suboptimal. Understanding kuvanlaadunheikennys is crucial for preserving images, whether analog or digital, and for making informed decisions during image creation, editing, and display.
