Kuvankappaus

Kuvankappaus, often translated as image cropping, is a fundamental image editing technique used to remove unwanted outer areas of a digital image. This process involves adjusting the boundaries of the image to create a new, smaller image that focuses on a particular subject or area of interest. Cropping can be used to improve composition, eliminate distractions, or change the aspect ratio of an image. It is a non-destructive editing process in most modern software, meaning the original image data is preserved, and the cropped area can be restored if needed.

The process typically involves selecting a rectangular or elliptical region within the original image. The software then discards the pixels outside this selected area. The resulting image is smaller in dimensions, both in width and height, and therefore has a reduced file size. This can be beneficial for storage and faster loading times on websites. When cropping, photographers and editors consider elements like the rule of thirds, leading lines, and the main subject to create a more aesthetically pleasing and impactful image. Different aspect ratios, such as square, 16:9, or the original aspect ratio, can be achieved through cropping. Kuvankappaus is a common feature in almost all image editing software, from professional tools like Adobe Photoshop to basic built-in applications on smartphones and operating systems.
