Kuvaresoluution

Kuvaresoluution, commonly written kuvaresoluutio in Finnish, refers to image resolution—the amount of detail contained in a raster image. It is typically defined by the number of pixels that make up the image, expressed as width by height in pixels (for example, 1920×1080). The total pixel count indicates potential detail, but perceived sharpness also depends on pixel density when the image is displayed or printed, described as dots per inch (DPI) for print or pixels per inch (PPI) for screens. Raster images have fixed resolution, so scaling them changes apparent sharpness and can introduce artifacts, whereas vector graphics are resolution-independent.

In practice, higher resolution enables finer detail and larger print sizes but increases file size. For web use, resolution is often limited by display size and bandwidth; typical targets are 72–96 PPI, with image dimensions chosen to fit the layout. For printed media, 300 DPI is a common standard for photographs and professional work, reducing visible pixelation at standard viewing distances; larger formats may require 300–600 DPI or more.

Resolution interacts with other factors such as color depth (bit depth) and compression. When using digital cameras, the sensor determines the native resolution, while post-processing can change the sampled resolution. Understanding kuvaresoluution helps balance image fidelity, file size, and the intended medium, whether for display on screens or for print.
