Resolution, measured in dots per inch (DPI), refers to the quality of detail in a given image. The higher the DPI number, the more pixels the picture has per square inch. The more highly concentrated the pixels are within a photo, the higher the resolution of the resulting picture. Photographs that have high resolutions will appear less grainy and crisper. Its details will be sharper and its borders better defined.
When a photographer wants to enlarge or downsize an image, he must remember the resolution of the original photo.

Only images with high resolutions can be manipulated while retaining the quality of the original.
