300 ppi VS 72 ppi
Pixel Per Inch (PPI) is a metric typically used to describe the pixel density or also known as ''sharpness'' for all displays such as cameras, mobile devices, computers, ETC. Basically, this is how many pixels can fit in one inch, which will make the image look way better in quality. When you compare 300 ppi VS 72 ppi, it's pretty easy to tell which one will look better, specially when you print it, which is one of the clearest ways to find the real difference. Here are two images rendered by me with 300 ppi and 72 ppi using Photoshop CS6. 300 PPI 72 PPI
