What does the size of the photo mean?
Simply put, photo size refers to the height and width of an image in pixels. It also represents the resolution of a photo that can be measured in pixels. For example, a 30 megapixel (MP) camera takes images with dimensions of 4480×6720 pixels. These dimensions allow printing up to 30×45 sizes in excellent condition. When it comes to photo size, it’s important to remember that the higher the image setting, the larger the image and file size.
Why resize the photo?
There are several reasons why your photo would need to be resized. The first is that it must be printed at a particular size that is different from its original size. Second, there are certain parts of your photo that need to be cut or cropped. Some photos have jagged edges or jagged parts that need to be removed, and resizing the image is a solution for that.
