Cropping an Image Cropping an image will reduce the resolution of the image, however rather than reduce the resolution of the whole image, a section of the image is instead cut or cropped and a new, smaller image that is focused on a certain area of pixels is created.
Some digital cameras have what is know as digital zoom.
Digital zoom is essentially another name for cropping the image and the same process is used. Wide x 300 High Let's say we want to remove the power lines from this image, I will select the area within the red box and crop. Wide x 210 High Starting with a much higher resolution original image allowed me to crop the interesting part of this picture while avoiding the power lines and the underexposed sections on the image. Some software packages allow you to stitch together two or more images to make one large image with just a few simple steps. In the example below, the two images have been combined then slightly cropped.
