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 refers to pixels per inch while the term DPI in contrast means dots per inch. PPI refers to the pixels numbers that can be supported by a camera's sensor in a certain given time. Additionally, it could be used to refer to the photo sizes a camera can produce. Most professionals refer to this as mega pixel. Dots per inch in contrast refer to the way in which an image or a photo is printed on the printing paper.

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.

Differentiating accurately between these two terms is vital for anyone who considers this practice to be a profession. An expert in this area has to be aware of the fact that the image produced on the printing paper does not necessary have to appear exactly the way it is portrayed on the screen. Note that the image might be very clear on the screen but have a blurred appearance when on the print, if the device is improperly set. The DPI will always come to make a conversion of pixels into dots that are readable and useful to the printer after the PPI has given the image's resolution.

Different digital gadgets will have different pixels per inch. A professional should be knowledgeable of the fact that other digital cameras have higher resolution ability in comparison than others. If the device has a higher PPI, it is expected to produce images that are highly pronounced. On the contrary, a low PPI will produce images that are less pronounced. These gadgets will also have a variation of dots that their printers can hold. The information on the type of dots a printer holds will always be indicated on the device's box.

Notably, the pixels per inch are always bigger that the dots per inch. By dividing the PPI by two, you will get the value of DPI that the device consists - making the difference explicit.

Lastly, the overall number of pixels that an image has can actually tell how big or small the image can be when printed, image quality kept constant. However, experts in the photography field advice that for any image to be of good quality, the pixel per inch must not be below 300. The dot per inch is composed of several color blends that gives an image its full colors while being printed.

In conclusion, PPI and DPI explained in explicit terms has solved the jig saw puzzle that has proved a hard nut to crack over the years. Professionals in this field are advised to toe the line by fathoming the very obvious differences between the two terminologies.
