Most people in the photography world confuse between the terms PPI and DPI and this has been the case for quite some time. As a matter of fact, there are several photographers who use these words interchangeably. For this reason, it is essential to have both PPI and DPI explained in detail to shed some light on their meaning to such photographers and any other person preparing for entry into the photography world.



PPI - pixels per inch refers to the pixels number that a camera sensor is able to support in a particular time. This term also refer to the sizes of a photo that a camera can produce. Most of experts in this field will refer to it as the mega pixel. DPI - dot per inch is always used to refer to the way an image or photo gets imprinted.



Ideally, whereas the pixel per inch concerned with digital images gives an illustration with regard to the resolution of the image as it appears on the screen, its counterpart deals with the image at the time it is printed on the printing paper.



In order to do professional work, photographers need to discern with ...
... meticulousness the two terms. They need to comprehend the facts that not necessarily will an image be printed the exact way they appear on the screen. If not properly set, an image may appear blurred on the print while on the screen it was clear. While PPI gives the resolution of the image, the DPI comes in a special way to convert the pixels into dots that the printer will be able to read and utilize.



It is important to note the fact that the pixels per inch vary from one digital device to another. There are digital cameras for example that have a higher resolution power while others have a lower resolution power. The higher the PPI the more pronounced the image will be and vice versa. Likewise, the number of dots a printer can hold also varies. Some printers can hold larger ones while some are smaller. Usually, manufacturers will indicate the DPI of a printer on the box.



Size is another variation between the two. Dots per inch are usually smaller than the pixels per inch. It is a golden rule that to determine the dots per inch, you just divide the pixels per inch by two. For instance, an image with 200 pixels per inch, it will have 100 dots per inch.



Lastly, when the quality of the image is not adjusted, the overall pixels number that is contained in an image can hint on the image's size when printed. It has been concluded by specialists in this arena that pixels per inch that are below 300 will not produce an image of good quality. Dot per inch contains a number of color blends, which ensures the image has its full colors during printing.



Therefore, the above information that sees PPI and DPI explained clearly is very useful in solving the confusion that exists in this area c of photography. It is important for photographers to get the difference between the two terms by understanding the obvious differences that are discussed above.
